Our top picks for small business

1Best value, and best free plan
Brevo logo

Brevo

4.6Capterra£6/mo (Starter)

Brevo prices on emails sent rather than contacts stored, so its free plan holds unlimited contacts and 300 emails a day, which suits a small business with a decent list it emails now and then. Paid plans start at £6 a month, the cheapest serious option here, and you get email, SMS and a light CRM in one tool rather than email alone.

  • Free plan with unlimited contacts (capped at 300 emails a day)
  • Cheapest paid entry point at £6 a month
  • Email, SMS and CRM together

Watch out: The daily send cap on the free plan means a business that emails a large list on one day needs to upgrade.

2Best British platform for small business
EmailOctopus logo

EmailOctopus

4.8Capterra£9/mo (Pro)

EmailOctopus is a British-built platform with an unusually generous free tier, up to 2,500 subscribers and 10,000 emails a month, and a clean, no-nonsense interface. Paid plans start at £9 a month, and it publishes a genuine pounds rate card rather than a converted US price, so a UK small business gets straightforward value with local billing.

  • British-built with a genuine pounds rate card
  • Very generous free tier: 2,500 subscribers, 10,000 emails a month
  • Simple and affordable, from £9 a month

Watch out: Deliberately lightweight, so it has fewer advanced automation and reporting features than the bigger tools.

3Best all-rounder for a small list
MailerLite logo

MailerLite

4.7Capterra£9/mo (Comfort)

MailerLite is the clean, easy all-rounder: good-looking templates, a simple automation builder and a genuinely usable free tier for up to 250 contacts and 2,500 emails a month. Paid plans start at £9 a month, and for most small businesses it hits the sweet spot of capable enough without being complicated.

  • Simple, well-designed builder and templates
  • Free plan for up to 250 contacts, 2,500 emails a month
  • Affordable paid step at £9 a month

Watch out: Priced per subscriber, so the bill grows steadily as your list does.

4Best for newsletters and creators
Kit logo

Kit

4.6Capterra£0 (free to 10K)

Kit, formerly ConvertKit, is built for newsletters, creators and audience-first businesses, and its free Newsletter plan runs to 10,000 subscribers, far more generous than the others on list size. The trade-off is that the free plan includes only one automation and no A/B testing, so it is superb for growing an audience and sending broadcasts, and you pay when you want serious automation.

  • Free up to 10,000 subscribers, the most generous list cap here
  • Built for newsletters, creators and audience growth
  • Clean subscriber and tagging model

Watch out: The free plan allows only one automation and no A/B testing, so automation-heavy users pay sooner.

Estimates based on £15,000/mo volume. Rates can change without notice, confirm current pricing with the provider before signing on.
How we calculate this
  • Estimated cost: each provider’s published prices and rates applied to the inputs you set above (such as volume, team size, or invoices), plus any fixed monthly fees.
  • Providers with an incomplete cost (shown as “+ processing”) and quote-only providers are never ranked as the cheapest while a complete-cost option exists. A “+ payroll” tag means payroll is not built in, so you would run it on separate software; those providers are still ranked on cost, and you can hide them with the Payroll included filter.
  • These are estimates. Published rates can change and your final pricing depends on your business, so confirm current pricing with the provider before switching.
Compare all Email Marketing

For a small business, email marketing is one of the cheapest ways to reach customers who already know you, and the good news is you can start for nothing. The real decision is not the headline price but the free tier's caps and how fast the paid plans step up once you outgrow them, because a "free" plan that is unlimited on one axis and tight on another can flip which tool is cheapest for you. Below are our ranked picks, then a live comparison table and calculator to cost each at your list size.

How we chose

For a small business we weighted the free tier and its real caps first, then ease of use, the quality of core sending and automation, and how quickly the paid plans step up as your list and send frequency grow. We paid particular attention to what each free plan actually limits, contacts, sends, or automation, because that is where the honest cost of a "free" tool hides. Pricing is live from our database in pounds, excluding VAT.

What a small business should prioritise

Match the tool to how you will actually use it. If you have a large list you email occasionally, Brevo's send-based pricing and unlimited-contact free plan is hard to beat. If you want a British tool with local billing and a generous free tier, EmailOctopus is the pick. If you send regularly to a small, growing list, MailerLite fits well, and if you are really running a newsletter, Kit's 10,000-subscriber free tier stands out. Read each free plan's caps before you commit, because the limit you hit first decides when you start paying.

Free tiers, and the caps that actually bite

Every free plan is generous on one axis and tight on another, so the useful question is which cap you will hit first. Brevo is unlimited on contacts but stops at 300 emails a day. EmailOctopus is unusually generous at 2,500 subscribers and 10,000 emails a month. MailerLite covers 250 contacts and 2,500 emails a month, and Kit runs to 10,000 subscribers but limits you to one automation and no A/B testing. Knowing your list size and send pattern tells you which free tier lasts longest for you.

The verdict

Brevo is the best value for a UK small business: a free plan with unlimited contacts and the cheapest paid step at £6 a month. EmailOctopus is the standout British option with a very generous free tier and local billing, from £9. MailerLite is the best all-rounder for a small growing list at £9, and Kit is the pick for a newsletter or creator, free to 10,000 subscribers. Use the calculator above to cost each at your list size and send frequency.

Frequently asked questions

What is the best email marketing platform for a small business in the UK?

For value it is Brevo: a free plan with unlimited contacts and 300 emails a day, and the cheapest paid entry at £6 a month. EmailOctopus is the standout British option with a free tier of 2,500 subscribers, from £9 a month. MailerLite is the best all-rounder at £9 a month, and Kit is the pick for a newsletter or creator, free to 10,000 subscribers. Use the calculator above to compare at your list size.

Is there genuinely free email marketing for a small business?

Yes, with caps worth understanding. Brevo's free plan holds unlimited contacts but caps sends at 300 emails a day. EmailOctopus's free plan covers up to 2,500 subscribers and 10,000 emails a month. MailerLite's covers 250 contacts and 2,500 emails a month, and Kit's runs to 10,000 subscribers but allows only one automation and no A/B testing. All four are genuine ongoing plans, not trials.

Is there a good British email marketing platform?

EmailOctopus is the standout: British-built, with a genuine pounds rate card rather than a converted US price, a very generous free tier of 2,500 subscribers, and paid plans from £9 a month. It is deliberately lightweight, so if you need deep automation you may prefer MailerLite or Brevo, but for straightforward UK small-business email it is excellent value.

Do I need to worry about consent when I send marketing email in the UK?

Yes. UK rules require a lawful basis and, for most marketing email to individuals, prior consent, so keep a record of how and when each subscriber opted in and always offer a clear unsubscribe. Every platform here supports consent capture and one-click unsubscribe; the responsibility for holding evidence of consent is yours rather than the tool's.
