Billing basis

Different platforms price different things

"Cheaper" only means something once you know what the price is actually measuring. Email platforms do not all charge for the same thing, which is why the same list can cost wildly different amounts depending on where it lives.

Contact-basedThe bill is set by how many contacts you hold, in brackets. Cross a bracket ceiling and the price steps up, whether or not you send them anything that month. Most ESPs, including the platforms compared above, price this way.

Send-basedThe bill is set by how many emails go out, not by list size. A large, quiet list can cost less than a small, active one. Fewer platforms price purely this way, and it usually comes with its own contact cap per tier.

Billable subscriber or active profileSome platforms price by a billable subscriber or active-profile count rather than every contact stored. There is no shared definition of that count across vendors: it can mean subscribed and not unsubscribed, a billable-subscriber rule, an active profile, or recent engagement, depending on the platform. Each row's details say what that vendor's own number represents.

Sized off the bracket, not your listSends included with a plan are often sized off the top of your bracket, not your actual contact count. A workload sitting well under a bracket's ceiling can end up with a much bigger send email included than the number it is actually using.

How we verify pricing

Every figure in the table above traces back to a rule, not a guess. The methodology, plainly:

List price only. Promotional and discounted prices are never compared or sorted against list prices. Where a vendor publishes a promo, it shows as "Promo available" and the terms sit in that row's details, kept apart from the number used for ranking.
No extrapolation. A workload beyond every published tier shows as "Contact sales", not a number we projected past the vendor's own ladder.
No manufactured figures. Where a vendor does not publish enough to confirm a price at your numbers, the row says so plainly rather than showing an estimate we could not check.
Confidence and dates travel with the number. Each row's details carry when the price was checked, the source it came from, and whether a currency conversion was assumed.

Vendors set their own prices and change them without telling us. If a number here looks wrong, tell us and we will check it.
