The mod portal doesn't officially support email notification on updated mods/discussions (yet), so I decided to create a little workaround.
I have a web server setup to pool information on any subscribed mod. Whenever a mod/discussion changes an email notification will be sent out to any subscribed user.
It's easy to subscribe for email notifications.
1. Navigate to http://factoriomods.zinals.nu/index.php/
This form should appear: 2. Fill in the url of the mod (for example: https://mods.factorio.com/mods/Zinal/SP_Respawn) in the first field (Mod Url). The second field should automatically detect the mod name (in this case: SP_Respawn)
3. Fill in your email address. This email will get notifications whenever the mod is updated.
4. Check your inbox, an email containing a confirmation link should soon appear.
5. Click the link and you'll get an email whenever the mod is updated!
I've also created both a Greasemonkey script (for Firefox users) and a Tampermonkey script (for Chrome users). These scripts will add a "Subscribe to mod" button on a mod's page. Clicking the button should automatically open the form mentioned in step 1 and the url for the mod (step 2) should already be filled out. (Sorry IE users, no button for you).
Edit:
The scripts also makes it possible to open the thumbnails in a bigger view, just a little bonus

You can click these links to auto-install the scripts if you have Greasemonkey or Tampermonkey installed:
Greasemonkey Script: http://factoriomods.zinals.nu/resources ... pt.user.js
Tampermonkey Script: http://factoriomods.zinals.nu/resources ... pt.user.js
The button looks like this:
