Best email marketing software
Every figure below was read from the vendor's own pricing page on the date beside it. The ordering is cheapest entry price first — a basis you can check rather than a ranking you have to trust.
What “best” means on this page
“Best” is not a mood — it is whichever axis you actually care about, measured. Our record can say which tool is cheapest to start, whose free plan is real, who bills local currency and whose prices just moved; it cannot say which tool fits your work, which is what the full comparisons are for. Cheapest never means best — it means cheapest. Each verdict below names its axis, and every tool links to its own site so you can check us against the source. No vendor paid for any position.
Entry at £6/mo — the lowest published paid plan in this set. Cheap is a fact, not a verdict; the profile below says what you get for it.

Tool by tool
Brevosite ↗pricing ↗
A messaging platform that sends email, SMS and WhatsApp from one account, with a CRM attached — formerly Sendinblue. Paid plans start at £6/mo (Starter); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at £429/mo (Professional). It bills by country — entry $9/mo to a US reader and €7/mo in the eurozone, from our same-day reads.
Constant Contactsite ↗pricing ↗
One of the oldest email marketing services, aimed at small businesses and non-profits, with event invitations and social posting alongside email. Paid plans start at £8/mo (Lite); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at £89/mo (Premium). It bills by country — entry $10/mo to a US reader and €12/mo in the eurozone, from our same-day reads. Constant Contact publishes every plan as a 'starting at' figure that climbs with your contact count, which is why the bill and the advertised price drift apart over time.
GetResponsesite ↗pricing ↗
An email marketing platform with webinars, funnels and landing pages built in, which makes it a marketing suite rather than a pure newsletter tool. Paid plans start at £13/mo (Starter); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at £51/mo (Creator). It bills by country — entry €16/mo to a US reader and €16/mo in the eurozone, from our same-day reads. GetResponse prices by list size and charges in your local currency, which makes it look dearer or cheaper than it is depending on where you read about it.

Billed in another currency
These tools are in the same category but did not show us a price in GBP on our last read — they quote the currency shown. We list them rather than convert: a converted figure is not a price anyone is charged.
Sendersite ↗pricing ↗
A low-cost email and SMS marketing tool for small businesses and online shops. Paid plans start at $7/mo (Standard); a free plan exists. The ladder we hold runs 2 paid tiers, topping out at $14/mo (Professional). We read the same $7/mo in every market we check, so this vendor does not price by country. It quotes USD here rather than local currency, so your bank sets the conversion.
Mailjetsite ↗pricing ↗
An email service covering both marketing campaigns and transactional sending, with collaborative template editing. Paid plans start at $9/mo (Starter); a free plan exists. The ladder we hold runs 3 paid tiers, topping out at $27/mo (Premium). We read the same $9/mo in every market we check, so this vendor does not price by country.

MailerLitesite ↗pricing ↗
A deliberately simple email marketing tool: newsletters, automations, landing pages and forms, aimed at creators and small businesses who want the essentials without a suite around them. Paid plans start at $12/mo (Comfort); a free plan exists. The ladder we hold runs 2 paid tiers, topping out at $25/mo (Power). MailerLite is already the cheap answer in this category, so people leaving it are usually after something it does not do rather than a lower bill.

A long-established email marketing service for small businesses, covering newsletters, autoresponders and landing pages. Paid plans start at $12.49/mo (Lite); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at $20/mo (Done). We read the same $12.49/mo in every market we check, so this vendor does not price by country. It quotes USD here rather than local currency, so your bank sets the conversion.
Flodesksite ↗pricing ↗
An email tool whose selling point is design: template-led newsletters for creators and small brands who care what the email looks like in the inbox. Paid plans start at $25/mo (Lite); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at $54/mo (Everything). We read the same $25/mo in every market we check, so this vendor does not price by country. It quotes USD here rather than local currency, so your bank sets the conversion. Its published prices moved on 2026-08-29 — the change log holds the rows. Flodesk retired the flat unlimited price for new members on 2 December 2025, by its own FAQ. Anyone who chose it for that reason is now shopping again.

How to choose in this category
- Most tools price by list size — a quoted price is only true at a stated subscriber count, so re-check the ladder at yours.
- Free tiers differ in what they cap: subscribers, sends or features. Two ‘free plans’ are rarely the same thing.
- Headline prices are often the annual-billing rate; the pay-monthly figure sits higher.
