Email is the only channel you own outright, which is why the choice of platform outlives most of the campaigns run on it. This guide ranks the platforms on deliverability, what the price does as the list grows, how much automation you get before the next tier, and whether you can take your subscribers and their history with you when you leave.
Positions one to six in this ranking are commercially available. Paid placement moves the order and nothing else: it never decides whether a product is listed, and it never changes a word of what its entry says. How that works · full disclosure.
Send-volume pricing instead of per-contact pricing
#1 of 8 in Email marketing
Charges for what you send rather than how many contacts you store, which is the cheaper model for a large but quiet list. The automation builder is capable without being a project, and transactional sending is on the same account. Reporting is the weakest part.
The default, with the ecosystem to match
#2 of 8 in Email marketing
Still the easiest platform to hand to a non-marketer, and the one with an integration for everything. The per-contact model means the bill grows with the part of your list that never opens anything, so audit before you renew.
Built for ecommerce, priced for it too
#3 of 8 in Email marketing
The strongest choice if your list is attached to a store: product, order and browse data sit natively in the segmentation rather than arriving through a connector. For a non-ecommerce list it is expensive for what you use.
Cheapest credible option for a growing list
#4 of 8 in Email marketing
Does the ninety per cent of email marketing most teams actually need, at roughly half what the incumbents charge. Approval is manual for new accounts, and the automation logic runs out at genuinely complex branching.
Automation depth closer to a marketing suite
#5 of 8 in Email marketing
The automation builder is the reason to pick it: multi-branch, cross-channel and genuinely conditional. That power costs setup time, and teams that only need newsletters end up paying for a machine they never start.
Ecommerce automations without the Klaviyo bill
#6 of 8 in Email marketing
Ships the abandoned-cart, win-back and post-purchase flows already built, which is most of what a small store needs. Segmentation is shallower than Klaviyo once your catalogue gets complicated.
Aimed at small businesses that want a phone number to call
#7 of 8 in Email marketing
Sells support as the product, and for a business without a marketer that is a fair trade. The automation and segmentation are a generation behind, and the price does not reflect that.
Design-led email for brand teams
#8 of 8 in Email marketing
The best of this group at making an email look designed rather than assembled, with client accounts that suit agencies. Automation is basic and the platform has seen little investment since its acquisition.

Country is where the vendor is headquartered or contracts from, which is a different question from where your data is hosted. Where the two tell different stories, the entry says so.

Brevo leads our ranking of 8 email marketing tools. Charges for what you send rather than how many contacts you store, which is the cheaper model for a large but quiet list. The automation builder is capable without being a project, and transactional sending is on the same account. Reporting is the weakest part.
We rank on what separates products after the demo: setup effort, what the price becomes with the modules most buyers need, and how hard it is to get your data back out. Paid placement can move a listed tool up the order and never changes what its entry says. Our method is on the editorial process page.
