What it does
Sending email straight from a WordPress server often means messages get delayed or end up in spam folders, and you have little visibility into why. This addon hands the sending job to Postmark, a dedicated email delivery service, while you keep building and managing your lists and campaigns inside the Newsletter plugin you already use. The goal is to get your messages into subscriber inboxes more consistently.
Once connected, the addon covers both regular newsletters and transactional messages such as account notifications. You get delivery tracking with reports on opens, clicks, bounces and successful deliveries, which helps you troubleshoot problems and judge how campaigns perform. Bounces and complaints are handled automatically, which helps protect your sender reputation. Configuration happens within the existing Newsletter plugin, so it fits into your current workflow without much technical effort.
Best for
- Sites already using the Newsletter plugin for email lists
- Businesses sending account notifications and other transactional emails
- Publishers who want delivery reports on every newsletter
