Postmark for WordPress

Fix WordPress email with Postmark

WP Mail SMTP routes every email your WordPress site sends through Postmark, so password resets, receipts, and notifications arrive with the same reliability as the rest of your transactional sending.

  • Transactional email that arrives
  • Keeps your streams separate
  • Set up in under 10 minutes
  • Free with WP Mail SMTP Lite

The Postmark deliverability you chose, now for WordPress too

Every transactional email your site sends, routed through Postmark with the same care as the rest of your sending.

Transactional email that arrives

Password resets, order confirmations, form notifications, and admin alerts all go through Postmark. No more wondering whether they made it.

Streams stay in their lanes

Use Postmark Message Streams to keep transactional separate from broadcast. WordPress emails route through the stream you point them to.

Subdomain reputation, intact

Verify a subdomain in Postmark and use it as your From Email. WordPress sending stays isolated from your root domain’s reputation.

Set up once, leave it alone

Paste your Server API Token, pick your domain, and you’re done. The whole setup takes under 10 minutes for most sites.

A safety net under your sending

Pair Postmark with a backup mailer. If anything goes wrong upstream, password resets and order confirmations still go out.

Route emails the way you want

Send transactional through Postmark and marketing through another mailer. Smart routing handles the split without any code.

Free with WP Mail SMTP Lite

The Postmark integration works with the free version of WP Mail SMTP. Upgrade to Pro when you want email logs, failover, and smart routing.

Verified Customer

good product and easy to setup. I love the premium version as it allows me to see if the customer received the mail and opened it. It even detected a best practice issue on my domain to avoid landing in my correspondent spam.

Your WordPress emails deserve to arrive

Install WP Mail SMTP, connect Postmark, and stop wondering whether your emails got through.

Common questions

Things people ask before connecting Postmark to WordPress. If your question isn’t here, get in touch.

Will this affect my Postmark deliverability?

WP Mail SMTP sends through Postmark’s API the same way any other client would, so your sender reputation and deliverability are handled by Postmark exactly as expected.

Do I need to verify a domain or just a single email address?

Either works. A single Sender Signature is fine if you’ll only ever send from one address. Verifying a whole domain is the stronger choice, since you can then send from any address on it without verifying each one individually.

What’s a Message Stream and which one do I need?

Message Streams are Postmark’s way of keeping transactional and broadcast email separate at the provider level. If WordPress is only sending transactional (password resets, order confirmations, form notifications), use the Transactional Stream. If you’re also sending newsletters, use a Broadcast Stream. Leaving the field blank in WP Mail SMTP defaults to the Transactional Stream.

Why does Postmark need to approve my account?

Postmark manually reviews each new account to protect its platform reputation. Approval usually takes one business day. You can finish setting up WP Mail SMTP while you wait, but you won’t be able to send to addresses outside your verified domain until approval comes through.

Made for sites where email isn’t optional

Logs to debug with, a backup to fall back on, and routing to keep things tidy. All managed from WordPress.
