Paid plans start at $15/mo. There's also a free plan.
Postmark starts at $15/month for 10,000 emails on Basic; Pro is $16.50 and Platform is $18 for the same included volume. The Free plan allows 100 emails/month and has no overages. Prices are monthly, and annual billing is not offered. The plan grid’s main gotchas are different sending-domain and retention limits, paid overages, and add-ons: dedicated IPs start at $50/month, while DMARC monitoring starts at $14 per domain.

03Which plan should you buy?
| If you are… | Get | Why |

04Is Postmark worth the money?
Postmark’s entry price is easy to read: $15/month gets 10,000 emails, and the higher plans keep that same included volume while adding domains, retention options, or inbound processing. The free tier is limited to 100 emails/month, and overages and add-ons can raise the bill. We can’t call it cheaper than alternatives from these prices alone. It looks worth considering when its listed sending and inbound features fit; agencies should price their volume and extras before choosing a plan.
Postmark pricing FAQ
How much does it cost to send 10,000 emails?
The listed monthly plans that include 10,000 emails are Basic at $15, Pro at $16.50, and Platform at $18. These are monthly allowances, not stated per-campaign prices. Free includes 100 emails/month, so it does not cover a 10,000-email monthly volume.
Is Postmarking mail free?
Postmark has a Free plan with 100 emails/month. The pricing details say it does not expire and allows no overages, so it is for testing, evaluation, and side projects—not a way to send beyond that monthly limit without moving to a paid plan.
Is Postmark a good site?
Postmark is an email delivery service with API and SMTP sending, templates, inbound email, and delivery analytics. Its pricing page lists separate infrastructure for promotional and transactional messages. Whether it is a good fit depends on your volume and required limits; the Free plan is only 100 emails/month.
