We wish to change to a 3rd party mail service for better delivery and metrics. Using a free (for now) account at sendgrid.com, we configured our DNS on the domain side and SMTP on the aMember side (smtp.sendgrid.net, SSL, port 465, username=apikey, password=API-from-Sendgrid) and our regular email delivery works fine. We would also like to get delivery metrics, bounces (bounce types), click-through stats, etc. and were figuring that one of the plugins Sendgrid or Sendgrid3 would do the job. Is there anyone with experience able to chime in for next steps? We are completely new to Sendgrid. Also, since we send just about 200 emails just a couple times a month, is the free account sufficient?
