PNG Alpha transparency in email

Handonam picture Handonam · Jul 26, 2012 · Viewed 9.2k times · Source

Is there support for PNG alpha transparency for popular email clients?

Here are the list of major e-mail clients i'm planning to support:

Web based*

  • Gmail
  • Hotmail
  • Yahoo

Software based

  • Outlook 2007/2010
  • Windows Mail
  • Mac OSX Mail
  • Thunderbird

Mobile based

  • iOS Device Mail
  • Android Device Mail

*This is browser-based, so no need to worry about this

From the research i've done, it seems all (mobile-based isn't listed, but i checked my phones) support PNG (http://en.wikipedia.org/wiki/Comparison_of_email_clients#Messages_features). But, I'm unsure as to whether or not they support transparency. Anyone have any good insight into this?

I've figured it out. I think that most will support PNG. I think that outlook 2003 used to have that problem because it was using the IE rendering engine. Nowadays, PNG is fairly acceptable. BUT, be a little careful with alpha transparencies.

But anyway, litmus has been the best thing i've used thus far. So, I suggest to use that if you are very serious about testing on all available platforms
