Postmark WordPress – message streams integration

Postmark Message Streams for WordPress and WooCommerce

We 🧡 Postmark. We use their service for all our transactional communication.

💡 All our email confirmations, post purchase emails in WooCommerce, or follow-ups are sent with Postmark.

Last year they shared their plan to also support marketing communication and bulk emails, i.e. newsletters, and product announcements. We couldn’t have been happier when we heard that! At that very moment, we decided to ditch Mailchimp and send our newsletters with ShopMagic Manual Actions.

We had to wait almost a year, but we finally got to their closed early access. We’ve tested the service and were very pleased with the results and wanted to introduce Message Streams to ShopMagic as soon as possible.

✅ Today you can also use Postmark for your marketing, newsletters, announcements, and all other communication sent with ShopMagic.

💡 ShopMagic lets you integrate custom emails with Mailchimp too!

How to enable Message Streams support

⚠️ To use Postmark, you’ll need their official plugin for WordPress. Configure it according to their instructions.
  • Add a new message stream in your Postmark account:
    Postmark WordPress
    Postmark Message Streams. Add New.
  • Copy the stream ID. In the example above it is newsletters.
  • Turn on the integration with a filter (for example in your functions.php):
    add_filter( 'shopmagic/core/postmark/enabled', '__return_true' );
  • Add an email action to your automation and fill in the stream ID:
    WooCommerce Guest Order Emails Shopmagic
    Postmark Message Streams. Shopmagic.
  • Done 🎉!

All emails from this action will be sent with this stream to protect transactional and broadcast messages 📧.
