I'm a very happy SendGrid user, but I simply cannot ignore the huge price difference. I will be giving Amazon a shot.
Before SendGrid, I was using Campaign Monitor, it was great, but outrageously expensive. SendGrid kicked off because it was an order of magnitude cheaper that CM, Mailchimp, etc. It seems that Amazon did to SendGrid what SendGrid did to "1 cent per email" providers such as Mailchimp.
Sorry for missing the point but this all seems like a lot of money for email. 100K/day outgoing is nothing that should tax a dual core CPU w/ SCSI disks and 100Mbps connectivity.
Are we talking about emails that aren't 100% legit? If so then what does SG offer other than an ever changing set of geographically disperse outbound MXs?
