The most recognisable email marketing brand, easy to start with and broadly capable, with steeper pricing as your list grows.
Best for
Beginners and small senders who want a familiar interface. Cost scales sharply once your list grows past a few thousand contacts.
Every fee we track, grouped by where it applies.
Mailchimp is the default first email marketing platform for many UK businesses. The interface is familiar, the template library is one of the largest in the category, and the free plan lets small senders trial the product on up to 250 contacts and 500 monthly sends. It bills UK customers in pounds.
The trade-off is cost as the list grows. Mailchimp bills for all contacts including unsubscribed ones, raised prices repeatedly since 2022, and cut the free plan from 2,000 to 250 contacts. SMS is a paid add-on on Essentials and above, sent to UK mobiles natively. Many growing businesses comparison-shop alternatives once they pass a few thousand contacts.
Mailchimp was founded in 2001 and is headquartered in Atlanta, USA.

The same questions UK merchants ask before signing up.
Mailchimp starts at £9.71/mo (Essentials) on the Essentials plan for a small contact list. A free tier is also available. Pricing scales by total contact count, and Mailchimp bills for all contacts including unsubscribed ones, so lists that are not regularly cleaned can become expensive.
Mailchimp bills UK customers in pounds (GBP), so there is no exchange-rate fluctuation on your invoice. The prices you see on the UK pricing page are the prices you pay.
The free plan supports up to 250 contacts and includes basic campaign sending and the drag-and-drop email builder. Automation, A/B testing, scheduling, and custom templates require a paid plan. The free tier was cut from a much higher limit in prior years, so older guides may show outdated figures.
Yes. Mailchimp counts subscribed, unsubscribed, and non-subscribed contacts toward your billed total. If you do not regularly archive or delete unsubscribed contacts, your bill rises even though those contacts no longer receive emails. This is one of the main cost complaints from long-term Mailchimp users.
Yes. Mailchimp offers SMS marketing to UK mobile numbers as a paid add-on on the Essentials plan and above. SMS credits are billed separately from the email subscription.
Yes. Mailchimp provides consent management, one-click unsubscribe, and sender identification tools that help you meet UK GDPR and PECR requirements for marketing emails.
