How email API pricing works
Email APIs mostly sell monthly plans with an included send volume, then charge overage per 1,000 emails or force an upgrade to the next tier. A few, like Amazon SES, are pure pay-as-you-go. That means the cheapest provider at 10,000 emails is often not the cheapest at 1,000,000.
For each provider the calculator picks the cheapest plan that covers your volume and shows the effective cost per 1,000 emails. Open any provider's own calculator for a plan-by-plan breakdown, or browse all email API pricing and head-to-head comparisons.
Prices come from each provider's official pricing page and are re-checked regularly; changes appear in the APIs Price Index.
Email pricing calculator FAQ
How much does it cost to send 100,000 emails a month?+
Most email APIs charge between roughly $15 and $90 for 100,000 emails a month, depending on the plan. Set the slider to 100,000 to see each provider's exact plan and price, cheapest first.
What is the cheapest email API?+
At high volumes, pay-as-you-go infrastructure such as Amazon SES is usually cheapest per email; at low volumes, a provider's free tier can cost nothing. The ranking above recalculates for your exact monthly volume.
How does the calculator pick a plan?+
For each provider it selects the cheapest listed plan that covers your monthly send volume, including overage pricing when a plan allows it.
Are dedicated IPs and add-ons included?+
No. Estimates cover the base sending plan only. Dedicated IPs, extra users, validation credits and taxes are billed on top by most providers.
Why do some providers not appear?+
Providers with custom or unlisted pricing at your volume cannot be estimated honestly, so they are hidden unless you turn on “Show custom pricing”.
