What is Postmaster?

Postmaster is the definitive solution for emailing channel entries within ExpressionEngine. Create beautiful email templates using the live preview, and impose extremely fine levels of control to send emails exactly when you want. Whether it be from the publish entries page in the control, to Safecracker on the front-end, or in a custom application using the channel entries API, Postmaster is the perfect for almost any application.


Below are a few of the many features included with Postmaster. If you have questions about specific functionality, don’t hesitate to ask us about it.

Channel Entries

Send emails automatically when channel entries are created or edited. Postmaster’s parcels are used specify a channel, status, member group, categories, and/or custom conditional(s).

MSM Compatibility

Postmaster is completely compatible with ExpressionEngine’s Multi Site Manager. Manage all your sites’ email notifications with the same add-on.

Override System Emails

If you are running EE v2.5.x you can take advantage of Postmaster’s ability to take full control over system emails. You can send things like forgot password and member activation emails with any email service. It should take less than 5 minutes to configure.

Send Emails for Anything

With the all-new Hooks API, you can send an email for any hook within ExpressionEngine. Developers can even provide advanced integration and pass custom variables. New hooks are being added all the time, with 10 hooks to start.

Post-dated & re-occuring emails

Use CRON jobs to send email at anytime in the future. Specify a specific and/or relative date to give you the maximum amount of flexibility. You can even configure a parcel to send emails at re-occurring intervals.

CRON Notifications

Send emails with HTTP requests to specific URLs with CRON jobs that are designed to be sent specifically when you desired, and contain any message needed. Notifications can be used when neither a parcel or a hook is needed.

CartThrob Support

Full CartThrob support is included with Postmaster. Checkouts, subscriptions, and even abandoned cart notifications. All emails can be sent now or at anytime in the future using Hooks, and Notifications.

Email Services

Postmaster supports a variety of email services including MailChimp, CampaignMonitor, SendGrid, Postmark, PostageApp, Mandrill, Mailgun, and even a full featured API to create your own. Of course you can use your webserver to send emails too.

Email Campaigns

Postmaster provides the best way for clients to create and send email campaigns ‐ and without the client ever seeing a template! Once a parcel is configured, it’s just a matter of creating and editing an entry using the same fieldtypes they are already familiar with.

Manage Subscribers

I have to say I still love this add-on. Bute please be aware that the developer has gone (as he states himself on his site). So there will be no more support nor will there be future updates.
For now the solution is still wonderful

I bought this add-on and basically I found it too confounding for what I wanted to do. I tried contacting the developer pre/post purchase. No reply ever. Pretty bad experience all round.

Here be dragons! Developer support is non-existent (in 2015). Before you buy read the devot:ee support requests and notice how many people are asking for help and not getting any. You are on your own with this add-on.

I really did not want to give this add-on a bad mark, but it’s a warning to anyone that would be looking to purchase.  It works so far with EE 2.10.1, but there is NO support. There use to be but the dev looks to have went on permanent holiday.

Amazing add-on! Takes notifications to a whole new level with so much flexibility. Support is also top-notch - very responsive, going above and beyond.

Emails and notifications are a breeze to set up, edit and manage with Postmaster. Everything’s in one spot and you have a lot of triggering options plus the added bonus to choose from different transactional email services. Buy if you want to do emails in EE the right way!

We’ve used this module and it’s super useful and really well produced. FANTASTIC support from the developer too.  Definitely recommend!

Really impressed with this add-on. Very easy to create good looking triggered emails that send reliably. I’m also routing through Mandrill App to track my emails, and that was a breeze to set up. Highly recommended.

Incredible add-on. Very flexible. I can manage all sorts of email notifications that you wouldn’t think were possible, all in one place. Support is super-responsive, too.

This is great. I just built a form that notifies six different people all getting uniquely styled html emails, and all with a single click of a submit button. Amazing!

The perfect solution for more granular and customized entry notifications, plus a huge additional feature set there for your more advanced custom email needs. Impressive.
