Best Mailchimp Alternative for UK Businesses in 2025

Mailchimp was, for many years, the default recommendation for any UK business starting with email marketing. Its free tier was generous, its interface was approachable, and its brand was so strong that "just use Mailchimp" became a reflexive piece of advice from web designers, marketing consultants, and startup founders alike. That era has not entirely ended, but the Mailchimp many people remember is not quite the Mailchimp that exists today. Following its acquisition by Intuit in 2021, Mailchimp’s pricing has been restructured multiple times — the free plan is now limited to 500 contacts, paid plans are among the most expensive in the sector, and many features that were once straightforward are now gated behind higher tiers. For UK businesses that have been on Mailchimp for years and suddenly face a significant renewal bill, or for those starting fresh and comparing costs, there are now several genuinely excellent alternatives.

The email marketing sector has become competitive in the best possible way for customers: tools like Brevo (formerly Sendinblue), MailerLite, Kit (formerly ConvertKit), and EmailOctopus have matured significantly and now offer feature sets that match or exceed Mailchimp at materially lower price points. UK businesses also benefit from the fact that GDPR compliance is table stakes for any serious email platform serving European subscribers — the alternatives covered here all support double opt-in, consent-based data handling, and EU/UK data residency or processing standards. The right Mailchimp alternative depends on your use case: ecommerce automation, newsletter publishing, agency multi-account management, or simply sending a monthly update to a few thousand subscribers.

Brevo, MailerLite, and Kit — the main contenders

Brevo (formerly Sendinblue) is the most direct Mailchimp replacement for UK businesses that do a high volume of email sends. Unlike Mailchimp, Brevo prices primarily on the number of emails sent per month rather than the size of your contact list — a meaningful difference if you have a large list but send infrequently. The free plan allows up to 300 emails per day and unlimited contacts, which is more generous than Mailchimp’s free tier for list-heavy businesses. Brevo’s paid plans start at around £19 per month for 20,000 sends and include marketing automation, transactional email, SMS marketing, and a landing page builder. Its UK GDPR documentation is thorough, and data can be processed within the EU. The automation builder is capable and improving, though it is not quite as polished as Mailchimp’s at the high end.

MailerLite is the platform most commonly recommended to UK small businesses and bloggers switching away from Mailchimp, and for good reason: it is genuinely easy to use, the free plan is generous (1,000 subscribers and 12,000 sends per month), and the paid plans are significantly cheaper than Mailchimp for equivalent list sizes. MailerLite includes email automation, landing pages, pop-ups, and a website builder on its free plan — features Mailchimp charges for. Kit (formerly ConvertKit) is aimed squarely at creators, bloggers, course sellers, and newsletters — its subscriber-tagging and segmentation model is excellent for audience-based businesses, and its commerce features (selling digital products and subscriptions directly) make it a strong choice for UK content creators. Kit’s free plan covers up to 10,000 subscribers with no automation, and paid plans start at around £25 per month.

EmailOctopus and other budget options for UK businesses

EmailOctopus is worth specific mention because it is a genuinely competitive email platform built by a small UK-based team, and it is one of the most cost-effective options available for businesses with larger lists. The free plan covers up to 2,500 subscribers and 10,000 emails per month — considerably more than Mailchimp’s current free tier. Paid plans scale very affordably: 10,000 subscribers costs around £24 per month, compared to over £100 on Mailchimp’s Standard plan. The feature set covers email campaigns, automation sequences, landing pages, and basic segmentation. It is not the most feature-rich platform on the market, but for UK businesses that want simple, reliable email sends at low cost with good UK support, it is an excellent option that often gets overlooked.

For UK ecommerce businesses specifically, Klaviyo and Omnisend are worth evaluating as Mailchimp alternatives — both are designed around ecommerce data flows (abandoned cart, browse abandonment, post-purchase sequences) and integrate tightly with WooCommerce and Shopify. Klaviyo in particular has strong UK GDPR tooling and a reputation for driving measurable revenue from email automation, though its pricing is at the higher end. At Xpose in Norwich, we help UK businesses evaluate and migrate to the right email platform for their audience size, send volume, and automation needs — the "best" Mailchimp alternative is rarely the same for a blogger with 500 subscribers as it is for a WooCommerce retailer with 20,000 customers.

UK GDPR compliance and choosing the right platform

UK GDPR compliance is a non-negotiable requirement for any UK business sending marketing email. All the platforms covered here support the core requirements: double opt-in to confirm subscriber consent, unsubscribe links on every email, and the ability to export or delete subscriber data on request. Where they differ is in the depth of their data processing documentation and where subscriber data is stored. Brevo and MailerLite both process data within the EU and publish Data Processing Agreements (DPAs) that UK businesses can use to satisfy their record-keeping obligations under UK GDPR. Kit and EmailOctopus process data in the US but use Standard Contractual Clauses (SCCs) for UK/EU data transfers — acceptable under the UK-US data bridge arrangements.

When switching email platforms, the migration process itself requires care from a consent perspective. You can import your existing subscriber list to a new platform if those subscribers originally consented to receive email from your organisation — but you cannot use the migration as an opportunity to add contacts who did not opt in, or to re-enable contacts who had previously unsubscribed. A clean migration means exporting only active, consented subscribers from Mailchimp and importing them to the new platform, then testing a small segment before sending to your full list. Most platforms have a dedicated import guide, and the major alternatives all offer free trials or free tiers that allow you to set up and test your template designs and automation flows before committing.

Our view on Mailchimp

We are a Norwich agency established in 2015, and we have worked with businesses on both sides of this comparison over the years. Our honest view: the right choice depends on your business, your team and where you want to be in two years — not on which platform is currently the most talked-about.

If you would like a straight opinion on which makes more sense for you — or whether you should leave the decision alone entirely and focus on something that will move the needle more — a free, no-pressure conversation is always available.
