Best Mailchimp Alternatives UK 2026: Which Email Marketing Software Offers the Best Value?

By Will Corry | The Marketing Blog | Updated 3 November 2026

The best Mailchimp alternatives for UK businesses in 2026 include EmailOctopus, Brevo, MailerLite, Omnisend and ActiveCampaign. However, the cheapest option depends on more than the monthly subscription. How a provider counts contacts, restricts email sends and charges for automation can make a considerable difference to the final bill.

Mailchimp remains a capable email marketing platform, but its free account now supports just 250 contacts and 500 email sends per month. That gives a business with 250 subscribers enough capacity for only two full-list campaigns.

Several competitors offer more generous allowances. EmailOctopus, a British-registered company, provides a free plan for up to 2,500 subscribers and 10,000 monthly emails. Brevo offers a different pricing structure, while MailerLite counts active subscribers rather than every contact stored in the database.

These differences become particularly important for established businesses with thousands of customer records.

There are also UK-specific considerations that international comparison websites frequently overlook. Businesses must account for VAT, foreign currency charges, UK GDPR, the Privacy and Electronic Communications Regulations (PECR) and the practical costs of moving customer information between providers.

This guide examines the leading alternatives, identifies where their prices can be misleading and provides practical examples of how British businesses should compare them.

Best Mailchimp Alternatives UK: Quick Comparison

Free-plan information checked against official provider documentation in November 2026. The allowances are not directly comparable because the services apply different contact, sending and feature restrictions.

Our Main Finding

The most important difference between email marketing platforms is often how they calculate the number of contacts you are paying for.

Mailchimp’s documentation confirms that subscribed, unsubscribed and non-subscribed contacts can count towards its monthly contact limit. Archived contacts do not.

MailerLite takes a different approach. It counts unique active subscribers, excluding unsubscribed and bounced contacts from its subscriber allowance.

For a business with thousands of historical customer records, that distinction could affect subscription costs even before a single campaign is sent.

However, archiving contacts to save money must be handled carefully. Businesses still need to retain appropriate records of marketing objections and previous unsubscribe requests.

Mailchimp Alternatives UK: How Much Do They Cost in Pounds?

UK email marketing prices can be surprisingly difficult to compare.

Some providers publish sterling prices. Others display dollar-based subscriptions that British customers pay using a converted amount. Introductory discounts and annual billing commitments introduce further differences.

The following figures show advertised starting prices, rather than pretending that every entry-level plan provides equivalent features.

Prices reviewed November 2026. Sterling figures for ActiveCampaign and GetResponse are indicative advertised entry prices rather than verified checkout quotations. Taxes, features, contact counts and billing periods differ. Always confirm the final quote.

Why Brevo’s £6 Plan Is Not Suitable for Every Large Database

Brevo’s free plan allows businesses to store up to 100,000 contacts. This sounds attractive to companies with large customer databases.

However, the cheapest paid tiers work differently.

According to Brevo’s official pricing documentation, the early Starter tiers include the following contact restrictions:

The contact limits come from Brevo’s official documentation. The sterling tier prices were recorded in a UK pricing comparison on 30 September 2026 and should be checked again before purchase.

This creates an unusual situation.

A business holding 5,000 customer records may be able to store them on Brevo’s free account. But moving to the cheapest paid tier would not necessarily allow it to retain all those contacts within that tier’s limits.

The business could need a higher subscription even if it sends relatively few emails.

The lesson: Never compare email marketing services using sending allowances alone. Check how many contacts the particular paid tier permits.

EmailOctopus: A British Mailchimp Alternative Worth Considering

EmailOctopus deserves a place near the top of any UK-focused Mailchimp comparison.

The company operates through Three Hearts Digital Ltd, registered in England and Wales, with a registered office in London.

Its free Starter account currently permits up to 2,500 subscribers and 10,000 monthly email sends. That is ten times Mailchimp’s free contact allowance and twenty times its monthly sending allowance.

For an independent publication, charity, local business or consultant building an email audience, those differences could delay the need for a paid subscription.

What Does EmailOctopus Include?

The free plan includes an email editor, templates, basic automation, audience management and reporting.

However, free users face several restrictions. Emails carry EmailOctopus branding, reports remain available for 30 days, and the account permits one landing page, one form and one user.

The paid Pro plan removes several restrictions and offers more extensive design and reporting capabilities.

One detail British buyers should understand is that EmailOctopus publishes its paid prices in US dollars. Being a UK-registered company does not mean its subscriptions are charged in pounds or that all customer data is stored in Britain.

Who Should Consider EmailOctopus?

A regional publisher sending a weekly newsletter to 2,000 subscribers would generate around 8,000 email sends over four weeks.

That fits within EmailOctopus’s free monthly allowance, assuming the publisher remains within the plan’s other restrictions.

The same business could not run that workload on Mailchimp’s free plan.

EmailOctopus is therefore particularly interesting for businesses that want to grow a mailing list without immediately paying for features they do not need.

Its limitations become more relevant when an organisation requires complex sales automation, detailed retail marketing or additional users.

Our assessment: EmailOctopus is one of the more interesting alternatives for smaller UK publishers and businesses because its free allowance is materially larger than Mailchimp’s. Its paid pricing currency and functional limits still need checking.

MailerLite: When Subscriber Numbers Matter More Than Database Size

MailerLite is another alternative for smaller businesses, particularly those that want straightforward newsletters, landing pages and automated email sequences.

Its email editor and audience tools are designed for users who do not want to manage a complicated CRM.

However, there are two important developments that UK buyers should know.

The first concerns its free plan. On 16 June 2026, MailerLite reduced the allowance from 500 to 250 active subscribers. Its monthly sending allowance also fell from 12,000 to 2,500 emails.

The second concerns how it calculates subscriber numbers.

MailerLite counts unique active email addresses. Unsubscribed and bounced contacts do not count towards its subscriber limit.

This differs from Mailchimp, where unsubscribed and non-subscribed contacts can count towards billing unless they are archived or deleted.

A Practical Example

Consider a UK consultancy with 5,000 records in its marketing database.

Of these, 3,000 are active subscribers, 1,200 have unsubscribed and another 800 have not agreed to receive marketing.

Under Mailchimp’s contact-counting rules, keeping all those records in the active audience could increase the billed contact count.

Under MailerLite’s active-subscriber model, the 3,000 active subscribers would determine the relevant subscriber tier.

The final cost would still depend on the selected paid plan. However, the difference in how each company counts contacts is commercially important.

A company should not delete historical customer records purely to reduce its software bill without considering retention requirements and marketing objections.

Our assessment: MailerLite deserves consideration from businesses with established mailing lists and large numbers of inactive or unsubscribed contacts, provided its features meet their requirements.

Brevo: A Good Option for Businesses That Send Less Frequently

Brevo offers another approach to email marketing costs, with subscription tiers influenced by the volume of messages sent.

This can work well for businesses that contact customers occasionally rather than distribute several campaigns each week.

For example, a professional services firm in Bristol might have 1,200 active subscribers but send only one monthly newsletter.

The company may benefit from a smaller sending allowance than a similarly sized retailer running weekly promotions.

However, businesses must consider Brevo’s contact limits as well as its email allowances.

Its free plan permits 300 sends per day. That means a business cannot send a newsletter to all 1,200 subscribers on the same day without moving to an appropriate paid subscription.

Brevo also offers SMS and other communication channels, although these may involve additional charges.

Our assessment: Brevo deserves consideration where mailing frequency is relatively low, but businesses should price the actual contact and email volume together.

Omnisend: Best for UK Online Retailers

Online retailers should approach email marketing software differently from service businesses.

For a retailer, marketing emails are often connected to shopping activity rather than a fixed newsletter schedule.

Omnisend concentrates on this type of communication.

A WooCommerce retailer selling kitchen equipment, for example, might use email automation to contact customers who leave items in their basket, recommend products after a purchase or invite previous buyers to return.

These activities can generate revenue without requiring staff to prepare every message manually.

The Important Omnisend Pricing Detail

Omnisend’s free plan supports 500 monthly email sends to a maximum of 250 reachable contacts.

On its paid Standard plan, the monthly email allowance is calculated using the number of billable contacts multiplied by 12.

For example, an allowance calculated against 3,000 billable contacts would provide 36,000 email sends.

However, Omnisend’s definition of billable contacts matters. Retailers should check how the platform counts subscribers and other customer records before assuming their newsletter list represents the total billable database.

There is also a significant SMS distinction.

Omnisend changed its SMS arrangements in May 2026. New Standard customers cannot purchase SMS credit subscriptions under the same arrangements as customers on its Pro tier.

A UK retailer planning to combine text messaging with email automation should therefore confirm the relevant subscription and UK SMS costs.

Our assessment: Omnisend is a strong candidate for Shopify and WooCommerce retailers, but its value depends on the shop integration and the automation features the business will actually use.

Transpond: Another Option for UK Small Businesses

Transpond deserves consideration because it offers a sterling pricing selector and combines email marketing with other customer communication tools.

Its published UK prices start at £7.20 per month for Starter and £14.40 for Growth, based on annual billing and the default 250-contact selection.

The platform also offers social media scheduling, website chat and marketing automation features, depending on the selected tier.

For British companies using several separate marketing tools, that combination may justify closer investigation.

However, the additional features should not be mistaken for a direct improvement in email campaign performance.

A company that needs only newsletters may prefer simpler software. A business wanting to manage social activity and customer communication in one service may find Transpond more relevant.

It also advertises an SMS add-on for UK customers, starting at £12.50 per month on annual billing, with additional terms and usage costs to check.

Our assessment: Transpond is worth including in a UK shortlist, particularly for small businesses comparing more than email marketing alone.

ActiveCampaign and HubSpot: When a Basic Newsletter Platform Is Not Enough

For many British B2B businesses, the problem is not sending emails. It is managing what happens after someone responds.

Consider a manufacturing software supplier receiving enquiries through Google Ads.

A prospect downloads a technical guide, receives follow-up information and eventually requests a demonstration.

The company may need to assign the prospect to a salesperson, record the enquiry, schedule further contact and track whether it becomes a sale.

A conventional newsletter platform can manage some of the email activity. More advanced marketing automation and CRM systems can connect that activity to the wider sales process.

ActiveCampaign supports detailed email journeys and contact-based automation.

HubSpot takes a broader approach by combining marketing with CRM records, deals, tasks and other customer activities.

Is HubSpot Worth the Extra Cost?

That depends on whether the business needs the wider system.

For a consultancy sending one newsletter each month, HubSpot’s advanced marketing subscriptions may be difficult to justify.

For a B2B company handling high-value enquiries, an integrated CRM could reduce administrative work and improve how sales opportunities are managed.

The financial comparison should therefore include the value of replacing existing systems, not simply the monthly cost of sending emails.

Our HubSpot vs Mailchimp comparison examines the differences between newsletter marketing and CRM-led sales activity.

For more information about subscription costs, see our HubSpot pricing UK guide.

How Many Emails Does Your Business Actually Need to Send?

Before buying an email marketing subscription, calculate the number of messages your business sends.

The calculation should include newsletters, promotional campaigns and automated emails.

Monthly email requirement = campaign recipients × campaigns per month + automated messages

The following examples show how quickly sending requirements can change.

These are illustrative business scenarios, not measured customer results.

The differences are significant.

A retailer with 2,000 subscribers may require almost as much sending capacity as a manufacturer with 5,000 contacts.

Meanwhile, a publisher could generate substantially more email volume than either business without needing advanced retail or sales automation.

This is why comparing platforms at an arbitrary contact number can produce misleading recommendations.

A Better Way to Request Quotes

Ask shortlisted providers to quote for the same combination of:

• Active subscribers and total stored contacts
• Expected monthly email sends
• Required automated messages
• Number of staff needing access
• Connections to WordPress, WooCommerce, Shopify or a CRM
• Reporting and segmentation requirements
• Monthly and annual billing
• Total price in pounds, including applicable VAT

Do not accept a cheaper quotation until the provider confirms that it covers the same workload.

UK GDPR and PECR: What Email Marketing Software Must Support

The choice of email marketing platform also affects how a business handles customer information.

In the UK, the main legal framework includes the UK General Data Protection Regulation, the Data Protection Act 2018 and the Privacy and Electronic Communications Regulations 2003.

UK GDPR regulates the processing of personal data. PECR establishes specific rules for marketing emails, text messages and certain tracking technologies.

The Information Commissioner’s Office (ICO) updated its detailed email marketing guidance on 28 April 2026.

For businesses comparing email marketing software, the important issue is not whether a provider uses the words “GDPR compliant” in its advertising. It is whether the business can use the platform in a way that meets its legal responsibilities.

Do UK Businesses Need Consent to Send Marketing Emails?

The answer depends partly on the recipient.

Businesses generally need prior consent to send unsolicited marketing emails to individual subscribers unless a recognised soft opt-in applies.

Individual subscribers include consumers, sole traders and certain partnerships.

However, PECR applies different rules to corporate subscribers.

A business sending marketing emails to corporate subscribers must still identify itself and provide an effective way to opt out.

Where a named employee’s personal data is involved, UK GDPR also applies. The sender needs an appropriate lawful basis and must respect marketing objections.

The rules therefore differ between emailing a limited company and contacting a sole trader.

Can You Email Existing Customers Without Fresh Consent?

In some circumstances, yes.

The products and services soft opt-in can permit marketing to existing customers or people who have actively negotiated a sale, provided the business meets all the conditions.

The company must have obtained the contact details directly during a sale or negotiations for a sale, and it must market its own similar products or services.

It must also provide a clear opportunity to opt out when collecting the details and in each subsequent message.

For example, a British retailer may be able to promote related products to previous customers who did not opt out, provided all the conditions are satisfied.

However, downloading a free guide, entering a competition or supplying an email address for an unrelated enquiry does not automatically establish permission to receive marketing.

The Data (Use and Access) Act 2025 also introduced a separate charitable purposes soft opt-in. This took effect in February 2026 and applies to qualifying charities under specific conditions.

Can UK Businesses Use American Email Marketing Platforms?

Yes. UK GDPR does not impose a general requirement to keep every customer’s personal information within Britain.

However, businesses must establish where their information is processed and whether the applicable international transfer arrangements are lawful.

For certain US transfers, organisations may rely on the UK Extension to the EU-US Data Privacy Framework where the recipient has the appropriate active certification.

Other transfers may require different safeguards.

The ICO updated its guidance on this arrangement in July 2026.

British businesses should therefore review each provider’s data processing agreement, processing locations, subcontractors and international transfer provisions.

A UK-registered supplier should not automatically be assumed to store all its customer information in the UK.

Are Email Tracking Pixels Legal?

Many email marketing platforms offer open-rate reporting that relies partly on tracking images embedded in messages.

These technologies may collect information about when a message is opened and the device used.

The ICO explains that tracking pixels fall within PECR’s rules on storage and access technologies.

Depending on how the tracking operates, consent may be required.

Therefore, businesses should check their provider’s tracking settings and assess whether their use of the technology complies with UK privacy requirements.

Why Suppression Lists Matter When Switching Platforms

This is one of the most important migration risks.

A company may have thousands of contacts stored in Mailchimp, including people who unsubscribed several years earlier.

When moving to another service, it must not treat those records as newly authorised marketing subscribers.

UK GDPR gives individuals an absolute right to object to the processing of their personal information for direct marketing.

The ICO recommends maintaining suppression records so that organisations do not accidentally contact people who have objected.

These records may need to be preserved even when other unnecessary personal information is removed.

The practical lesson: Never delete unsubscribe records merely to reduce the number of contacts in an email platform. First establish how to retain and enforce the relevant marketing objections.

The Hidden Cost of Moving from Mailchimp

Switching email platforms can involve more work than the monthly subscription saving suggests.

A company may have established welcome emails, customer groups, purchase-related messages and connections between its website and mailing list.

These systems must be recreated or transferred carefully.

For example, a WordPress website might use several newsletter forms, each assigning subscribers to a different interest group.

If the replacement provider does not receive the correct information, the business could lose the segmentation it previously used to target campaigns.

There are also technical considerations.

Changing providers can require new DNS records for email authentication, including SPF, DKIM and DMARC.

Google imposes additional requirements on organisations sending approximately 5,000 or more messages per day to personal Gmail accounts. These include stronger authentication and one-click unsubscribe support for relevant marketing messages.

However, a provider change does not guarantee better deliverability.

A poor-quality mailing list, frequent spam complaints or misconfigured authentication can cause problems regardless of which email service is used.

A Practical Mailchimp Migration Checklist

Before cancelling an existing subscription:

1. Export subscriber information, including relevant consent and contact-status records.
2. Preserve suppression lists and objections to marketing.
3. Check how tags, groups and custom fields transfer.
4. Rebuild the automated campaigns that are still required.
5. Reconnect WordPress forms, online shops and CRM integrations.
6. Configure and verify email authentication records.
7. Test campaigns, unsubscribe links and contact preferences.
8. Confirm that the new platform handles customer information appropriately.
9. Check that the sending domain and mailing list are performing satisfactorily.
10. Retain access to necessary historical records before closing the original account.

A successful migration should preserve the business’s ability to communicate with customers while protecting their marketing preferences.

Which Mailchimp Alternative Should a UK Business Choose?

The strongest option depends on the business model.

For a small company sending occasional newsletters, EmailOctopus and MailerLite deserve close attention because of their approach to subscriber allowances and straightforward campaign management.

Brevo is worth comparing when monthly sending volume matters more than frequent campaigns, although its paid contact limits need to be checked.

Omnisend offers a more specialised option for online retailers.

ActiveCampaign and HubSpot suit businesses where marketing responses need to trigger sales activity or more complicated follow-up processes.

Transpond may appeal to smaller companies wanting additional customer communication and social media tools within one subscription.

The key is to avoid buying a platform with far more capabilities than the business needs.

A simple, reliable service that staff use consistently can offer better value than an expensive automation system that remains largely unused.

Frequently Asked Questions

What is the best free Mailchimp alternative in the UK?

EmailOctopus deserves consideration because its free plan supports 2,500 subscribers and 10,000 monthly emails. beehiiv also supports 2,500 subscribers with unlimited sends for newsletter publishing. However, the best option depends on the features required and the restrictions attached to each plan.

Is Brevo cheaper than Mailchimp in the UK?

Brevo advertises a UK Starter plan from £6 per month, compared with Mailchimp’s displayed Essentials starting price of £9.80. However, the entry plans differ in contact allowances, sending limits and features. Businesses should compare prices at their actual contact and email volumes.

Is EmailOctopus a British company?

Yes. EmailOctopus operates through Three Hearts Digital Ltd, registered in England and Wales. However, its paid plans are priced in US dollars, and businesses should separately check its data processing and hosting arrangements.

Is MailerLite still free for 1,000 subscribers?

No. MailerLite reduced its free-plan subscriber allowance to 250 in June 2026. Businesses with 1,000 active subscribers require a suitable paid plan.

Does Mailchimp charge for unsubscribed contacts?

Mailchimp’s documentation confirms that unsubscribed and non-subscribed contacts can count towards monthly contact limits. Archived contacts do not. Businesses should review contact status and retention requirements before making changes to their databases.

Which Mailchimp alternative is best for WooCommerce?

Omnisend is worth considering because its automation features focus on online retail. However, WooCommerce retailers should compare integration requirements, contact allowances and the cost of sending purchase-related messages before choosing a provider.

Do British businesses need GDPR consent to send B2B emails?

Prior consent is not generally required under PECR for unsolicited marketing emails to corporate subscribers such as limited companies. However, UK GDPR may apply to personal information, and businesses must provide a valid opt-out and respect marketing objections. Sole traders are subject to different rules.

Can I transfer a Mailchimp mailing list to another platform?

Yes, but businesses must preserve relevant marketing permissions, unsubscribe records and customer preferences. They should also check whether the new platform can recreate existing segments and automation. Importing email addresses does not automatically authorise promotional messages.

Does email marketing software need to store data in the UK?

No. UK businesses can use overseas providers where the applicable data protection and international transfer requirements are met. They should review data processing agreements and transfer safeguards rather than assume that a provider’s location determines compliance.

Final Verdict: The Best Mailchimp Alternative Depends on How You Use Email

Mailchimp remains a credible option for British businesses, but its restricted free plan and contact-counting rules make competitors worth examining.

EmailOctopus offers one of the more generous free allowances among the services reviewed. MailerLite’s active-subscriber approach may appeal to organisations with large numbers of historical contacts.

Brevo’s sending-volume model provides another option, although its paid contact limits require attention.

For retailers, Omnisend offers specialised automation. Businesses with more demanding B2B sales processes should consider ActiveCampaign or HubSpot.

However, UK companies should compare the full cost of operating each service, not just the advertised subscription.

That means examining monthly email volumes, subscriber numbers, automation features, VAT, foreign currency charges and the time required to transfer existing campaigns.

UK GDPR and PECR requirements must also be considered before customer information moves to a new provider.

The most useful Mailchimp alternative is not necessarily the cheapest service. It is the platform that meets the company’s real requirements without unnecessary charges, technical complications or customer privacy risks.
