Email Marketing 4.51.2 Released!

We just released a new version of our ActiveCampaign Email Marketing software!

It doesn’t have a lot of updates, but the ones we do are VERY important!

Sending engine has been improved and optimized! We have tested it, and it looks like we have a 40% increase in email marketing delivery speed. This is the biggest increase we have had in a long time now. I hope you all feel the difference.

There was a problem in version 4.51 with Bounce Managament which was confusing our system. It used to mark successful email addresses as bounced due to this error. We have fixed it now, so I suggest that you check your Bounces to see if some email was marked as bounced by mistake. That won’t happen anymore.

Importing subscribers had a bug that was occuring only in certain cases. We have fixed it now, and we have also included unencoded PEAR files since we experienced some problems with those classes when the files were encoded.

In our Support Forum you can see the list of all changed files.

A trial is worth a thousand words.

    I just hope you could fix the problem with the fck-editor soon, so that I can use also the header and footer template for customers.

  • We are releasing new version right now. 4.51.3 has those bugs fixed.

  • I still always get the issue when I use the source editor that all & will be converted in to &ed;

    so my urls will look like


    instead of


    which causes system issues on our website

    I only can send our emails if I do a website import


  • Hi Christian,
    That happens because FCK editor is setup to use XHTML instead of HTML by deafult. We wanted to change that option in /admin/functions/editor/fckconfig.js but there it says that they recommend not to remove it. You can try and see if that works for you. Otherwise, you would have to wait for an update of FCK editor.
