Really looking forward to this integration.
Would be more then great. I'm using Mailgun right now for almost all of my sites, but I now have to activate, configure and install the plugin each time for a new site.
I use Mail Gun on all sites and do not use Sendgrid. How is this coming?
+1 for Postmark. Mailgun is better than Sendgrid, but from what I've read, Postmark takes the cake for deliverability.
