Today, out of nowhere, we started receiving reports that HTML email the gdiapers.com site was sending were showing up as just that: HTML code and not much else. Running a few tests confirmed these reports… but only in my gmail account. We went back and checked the reports and sure enough - they were all coming from gmail users.

After some tinkering and futzing around we realized that the Windows line breaks that we had after the headers (\r\n) were the problem. Here’s an example:

This will show up as two line breaks in gmail and trash your HTML formatting:
$headers = "MIME-Version: 1.0\r\n";

This, however, will fix the problem and show up in gmail just fine:
$headers = "MIME-Version: 1.0\n";

I’m sure if you were sending mail from a Windows server this may not be the case, but for those on a Unix box, just stick with \n. Google will thank you by displaying your HTML email the way it was meant to be displayed - without raw code!
