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 $7/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
Sendersite ↗pricing ↗
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).
Brevosite ↗pricing ↗
Paid plans start at $9/mo (Starter); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at $499/mo (Professional). It bills by country — entry £6/mo to a UK reader and €7/mo in the eurozone, from our same-day reads.
Constant Contactsite ↗pricing ↗
Paid plans start at $12/mo (Lite); no free plan is published. The ladder we hold runs 3 paid tiers, topping out at $80/mo (Premium). It bills by country — entry €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.
MailerLitesite ↗pricing ↗
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.
AWebersite ↗pricing ↗
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).
Flodesksite ↗pricing ↗
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). 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.
Kitsite ↗pricing ↗
Paid plans start at $33/mo (Creator); a free plan exists. The ladder we hold runs 2 paid tiers, topping out at $66/mo (Pro). Kit gives away up to 10,000 subscribers, so people looking past it are almost always after a feature rather than a price.

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.
