I have several Wordpress sites, one of which is using a newsletter subscription services whereby I can stage my own custom email templates. I have roughed-in a responsive template and know that the basic content substitutions work OK.
I need you to do the following:
1) Create a new default responsive email template, modeled roughly after the existing one (I'll give you both the template and the as-sent email).
2) Fix things so that it is fully responsive (for example, embedded graphics in the WordPress posts are not resizing well).
3) Test on all common email clients -- web, apps, desktop (Outlook, iOS, Android, etc.). Extra points if you use one of the email testing services and send me a cross-platform rendering report.
4) Include in the template some special CSS classes I use and make sure they work as advertised (for example, I routinely use one class to remove a shadow from embedded images).
As for process:
a) I'll receive your first cut of the template.
b) I'll test on my end to assure it is functioning.
c) I'll make change requests (being a former developer, I know how not to add feature creep to a project).
d) We'll repeat until all design issues are resolved.
e) You'll do your final cross-platform test.
Be sure to tell me if you will use a cross-platform testing service as this improves your odds of being selected.
Also extra points if you are familiar with the MailPoet plugin, are following the 3.x release schedule and can later morph your template to work with their software.
