We have had some issues with an email template recently. We created an email template which has been designed as responsive, using a service called Inkbrush and sent the email as a test to ourselves. The template turned out absolutely fine when received. When we looked at the header of the email, the encoding section, it had the below:
However, when we copied the same template onto our servers on the Amazon side which used a the Postfix service to send the email via our php mailer, the template arrived with some broken links with pictures with red crosses on them. The encoding on it was:
Content-Type: text/html; charset=UTF-8
What I wanted to know is whether the multipart being inserted into the actual first email being sent could be affecting everything? Also, how important is 'multipart' and what does it mean?
Thanks for helping
