## At a glance

| Criterion | MailerSend | Postmark |
| --- | --- | --- |
| Entry paid plan | $31.50/month for Starter, billed $378 a year. Professional is $99/month, billed $1,188. | $15.00/month for Basic at the 10,000-email tier. Postmark prices by volume, so the figure rises with the slider. |
| Pricing model | Volume plans quoted in USD, EUR or GBP, with SMS metered separately from email and a 500,000 daily API request ceiling on Professional. Annual billing is twelve months at a discount rather than ten. | One monthly price per volume tier, chosen on a slider, covering both sent and received email. Overage rates improve as the plan gets larger. |
| Emails included | 50,000 a month on both Starter and Professional — the plans differ on features and SMS allowance rather than email volume. | 10,000 a month at the $15 Basic tier. The plan price scales with volume — 50,000, 125,000, 300,000, 700,000 and 1.5M are the published steps. The free tier is 100 a month. |
| Price per 1,000 over | $1.30 per 1,000 emails on both Starter and Professional. | $1.80 per 1,000 on Basic, $1.30 on Pro and $1.20 on Platform. The free tier allows no overage at all. |
| Log retention | Two windows, which no other provider here separates: 7 days of API logs and 30 days of activity data on Professional; 7-day activity data on Starter. | 45 days on Basic. Pro and Platform default to 45 days and can be raised to 365. |

## Which should you choose?

Pick MailerSend if Teams sending email and SMS from one provider who need a longer activity window than a debugging log — 30 days of activity data against 7 days of API logs is a distinction the rest of this category does not draw.

Pick Postmark if Teams that need to answer "what happened to this message" weeks later — 45 days of retention as standard, extendable to a year, is the longest window in this set.

Consider something else: MailerSend — Both paid tiers include the same 50,000 emails, so paying three times more buys features rather than volume, and the entry price is the highest here.

Consider something else: Postmark — The included volume is small for the price and overage is the most expensive here at $1.80 per 1,000 on the entry plan.
