Send WordPress email through Postmark

Postmark is built exclusively for transactional email — no marketing-blast infrastructure competing for the same sending reputation — which is exactly the kind of mail WordPress and WooCommerce generate. NimblyMail SMTP connects your site to Postmark’s servers using a single Server API Token, giving you some of the fastest, most reliable delivery available for order confirmations, password resets, and admin notifications.

Postmark’s entire product is optimized around one thing: getting a single transactional message into an inbox as fast as possible. Because Postmark doesn’t send bulk marketing campaigns from the same infrastructure, its shared IP reputation stays clean, which independent deliverability tests consistently show translates into some of the best inbox placement rates in the industry.

Authentication is unusually simple — one Server API Token acts as both the SMTP username and password, so there’s less to misconfigure. Postmark’s message streams also separate transactional and broadcast mail internally (useful if you later add a newsletter stream), though both draw from the same monthly sending allowance.
