Postmark

What it is for

Postmark is a hosted servers-list desk: you open Servers, and Free is $0 / month. Use it when the job is transactional streams you start at $0, not when you need a $20 chat seat.

What makes it unique: the cover is the official Postmark Servers list (Web App Production 3,777 transactional / 984 inbound, Web App Staging, Helpdesk, Labs Project 1 issue, Create Server, 9,900 emails this period) from the product still — not a pricing card. The rows themselves are ops of Servers. Postmark bills $0 or $15 / $16.50 / $18 tiles, not a chat seat.

Key features

• Servers — an environment / client folder you create (cover still; blog). One list. Cover Web App Production and Create Server sit here.
• Activity — a processed / delivered / bounce event you search (blog; getting started). Activity, not a server row. CSV export sits here.
• Statistics — a sent / open / bounce chart per stream (blog). Stats, not Activity. 3,827 sent sits here.
• Templates — an HTML / text layout you send (templates API). A template, not a chart. Aliases sit here.
• Sender Signatures — a from-address / DKIM domain you verify (getting started; official video). A signature, not a template. 5 custom domains on Basic sit here.

The Jump-to-stream icons on the cover are shortcuts on Servers (not a sixth desk). Free / Basic / Pro / Platform tiles are the meter. Extra emails at $1.80 / 1,000 are the extra meter, not a desk we fold into Servers.

Who it's for

Best fit: app teams who will stay on Free at $0 (100 emails / month, no overages) while they open a first Servers list, then buy Basic at $15 / month (10,000 emails, extra $1.80 / 1,000) when they leave the 100-email bucket.

Pricing

Verified 2026-10-23 (Asia/Shanghai) from postmarkapp.com/pricing. Tiles print Free $0.00 / mo, Basic $15.00 / mo, Pro $16.50 / mo, and Platform $18.00 / mo.

• Free — $0 / month. 100 emails / month. No overages. Never expires. For testing an integration or a side project.

Confirm checkout; taxes follow your location. There is no published tile between 100 and 10,000 emails / month.

Limitations / costs

• Free caps at 100 emails / month with no overages. Crossing that is the $15 Basic tile (no 1k–9k plan).
• $15 includes 10,000 emails. Extra 15,000 at $1.80 / 1k is $27, so that month is $42 on the support example.
• A servers-list desk, not a Resend composer. For Resend see Resend. For Mailtrap see Mailtrap.

Alternatives

• Resend — transactional + marketing when you want Resend’s $0 / $20 desk, not Postmark’s $0 / $15 Servers list.
• Mailtrap — sending stats when you want Mailtrap’s $0 / $15 Stats tile, not Postmark’s Web App Production row.
• Loops — product email when you want Loops’ campaigns, not Postmark’s 3,777 transactional count.
