Paid plans start at $15/mo. There's also a free plan.
Postmark's Free plan costs $0 and includes 100 emails per month, with no overages allowed; it does not expire. Paid plans begin at $15 monthly for 10,000 emails on Basic. As sending grows beyond a paid plan's allowance, each additional 1,000 emails costs $1.80 on Basic, $1.30 on Pro or $1.20 on Platform. Plans are billed monthly, and paid overages are charged with the upcoming month's bill. Annual plans are not offered.

04Is Postmark worth the money?
Postmark's permanent 100-email Free plan works for evaluation and very small projects, but it is not a meaningful production allowance for most application email. Basic starts at $15 monthly for 10,000 emails; Pro and Platform cost $16.50 and $18, with inbound processing and different domain allowances. Model overages against expected volume, and include dedicated IP, retention or DMARC costs if your project needs them. There is no self-hosted option to substitute for the service fee.
