Postmark
Postmark is an email service provider specializing in fast, transactional email delivery (such as password resets, notifications, and order confirmations) via SMTP and API. It has separate infrastructure for promotional and transactional streams.
What you get
Ensures critical application emails reach the inbox rapidly and reliably by separating transactional and marketing email streams, minimizing delivery issues and enhancing user experience.
The problem it solves
Our customers were frustrated because password resets, order confirmations, and other crucial notifications were either delayed or landing in spam. This created a poor user experience and increased our support load. Postmark solved this by providing a dedicated, fast, and highly reliable email delivery service specifically for these essential transactional messages, so they always get through to the inbox quickly.
Who it's for
Postmark is a fit for these roles. Each one links to the rest of the tools we recommend for that work.
Pricing
Postmark's pricing is usage-based, determined by the monthly volume of emails sent. Plans start at a base price for a set number of emails (e.g., 10,000), with additional emails incurring overage charges per 1,000. There is a permanently free developer tier that allows sending 100 emails per month, ideal for testing the API but not suitable for any production-level email volume.
Plans change often. Check Postmark's own pricing page before you buy.
