Making mobile responsive and Outlook 2010/2013 friendly emails

[Brenden]

How can I remove / modify the line: <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> that appears in HTML emails.

 

I think this is causing my emails that look great in Outlook to not be responsive on an iPhone/Android.

 

Wondering if anyone has some suggestions or example templates they are using?

 

Are their any files I can modify in WHMCS for email HTML generation?

to modify email header/footer go to Admin Area > Setup > General Settings > Mail tab.

 

each Email client rendering emails differently, you may need to use Tables instead of Div and inline CSS

That line is likely from WHMCS and un-editable, as mentioned you can edit the email in the general settings.
