Best Free Email Marketing Software (UK)
The best free email marketing plans for UK businesses - what you get, what's limited, and when to pay.
Free email plans are a great way to start, but every provider limits something - usually the number of contacts, sends, or features like automation. This guide compares the best free tiers and explains the trade-offs. Free tiers change, so always confirm current limits on the provider's site.
How we chose
We assessed each platform against these criteria:
- Generous free limits (contacts and sends)
- Core features usable free (templates, basic automation)
- No surprise lock-in when you outgrow the free tier
- Good deliverability out of the box
Our picks
MailerLite
Best free plan overall
Free up to 1,000 subscribers with a genuinely good editor - the best 'permanent' free tier for small UK businesses and creators.
Best for: Small businesses and creators starting out
Brevo
Best for transactional + large lists
300 emails/day free every day; you can build a sizeable database without paying while you figure volume.
Best for: Growing lists and transactional email
Mailchimp
Best known free option
A small but well-known free plan; great to learn on, though automation features are limited.
Best for: Beginners learning email marketing
Several platforms offer free trials rather than permanent free plans. If a free tier is essential for the long term, prioritise MailerLite and Brevo. Remember: your contact data should be exportable regardless of plan so you're never locked in.
