# Postmark

Canonical: https://inetgeek.com/email/postmark/

Transactional email service priced by monthly volume, with configurable log retention and inbound processing.

## Who it suits

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 if 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.
