For those of you who enjoy tinkering with code, you’ll probably agree that one of the most attractive things about Postach.io is the ability to customize themes. While we had to temporarily remove the original Source Editor for a couple weeks in order to make some much-needed updates, we’re pretty stoked on the results of our efforts. We hope you will be too!

This week, our team is proud to finally reveal what you’ve all been waiting for:

A brand new Theme Editor, conveniently powered by:



In addition to our pre-made themes, Postach.io now comes equipped with a robust theming engine, powered by GitHub. You can create and edit a theme simply by connecting a Github repo to your site.

Note: Due to the relative complexity of this feature, we recommend you learn how to use GitHub first before attempting to edit your theme on Postach.io. We do plan to release a simpler, more ‘user-friendly’ theme editor in the future.

Here’s how to get started customizing you theme with Github:

1) Connect GitHub to Your Site

Log in to Postach.io and go to Edit Site > Source Code.


2) Fork an existing Postach.io theme to start (or create one from scratch)
  • Visit http://github.com/postachio
  • Choose a theme from the list of theme repositories
  • Click “Fork" to make a repository in your Github account with the theme
3) Select the repository for your theme

Log into Postach.io, go to Edit Site > Source Code and then choose the repository in your Github account of the theme you’d like to use. It will likely be the one you just forked in the step above, unless you’re creating a custom theme from scratch.

4) Make a change and push

Now that you’ve selected a theme repository, you’re all set up. The last step is to push some changes to your theme repository to make it live.

Note: changes to your theme are queued just like posts, so you might have to wait a few moments during high volumes.

If you’ve chosen one of our themes, you’ll want to run "npm install" and “gulp" in order to process LESS files to CSS and minify the javascript.

Apologies to be made...

To all of our fans who depended on the original source editor to manage their sites, we are truly sorry for temporarily removing it without proper warning or a comparable replacement. Since our team also must depend on tools like this to do our jobs effectively, we completely understand that this update process created a big inconvenience for some of you. We hope that this new Theme Editor serves even better than its predecessor and makes the wait worth while! Thank you all so much for your continued support :-)
