A few days ago we posted about a change we had made to the MailBuild editing page, to add a DOCTYPE. Our intentions were good (and in response to some customer requests), but clearly our testing was not extensive enough.

We've heard from quite a few people since then that have seen their templates behaving oddly in some browsers, with double scroll bars and broken layouts. None of this affected the rendering of the actual campaigns when sent, but it was very annoying and confusing.

So today we have decided to roll back to the previous stable state, which should correct all of those problems. If you had made changes to your templates to fix rendering that had changed, everything should still work for you, although we apologise for wasting your time.

We promise we won't make any changes like this again without giving you all adequate warning, and we've also rejigged our testing processes so we can pick these things up before release.

Thanks to everyone who has been in touch to let us know about these problems, and please accept our apologies for the trouble. If you have any problems, questions or feedback, please let us know by leaving a comment or emailing support.
