The whole idea behind Sendgrid is a joke.

It's become popular for some providers since the move to the Cloud to block outgoing port 25, but apart from that, you literally don't need Sendgrid. Any senior engineer can write a local "Sendgrid" in about half a day. Sendgrid doesn't even support all the RFCs properly, so, you'll likely get dropped mail if you move to Sendgrid from Postfix/Sendmail. Besides that, Sendgrid's UI/UX was terrible the last time I've played with it. It's literally the lamest startup there could possibly be.

As a customer of some unrelated service, I've already converted said service away from Sendgrid in just a couple of emails to the owner. (Sadly, they've moved to one of the many Sendgrid's competitors, not to Postfix/Sendmail, but the switch was obviously painless.) That's how horrible Sendgrid is, and how easy it is to make other people switch.

P.S. I often send mail through shell scripts. Try selling me Sendgrid when my laptop already comes with Postfix/Sendmail, with spool support. Does Sendgrid even work when you have no internet connection? (Rhetorical question: no, Sendgrid does not when internet is not available; but Postfix/Sendmail works just fine even without any internet, and will spool all your mail until you get connected to an internet with port 25 not blocked.) Sendgrid is a downgrade however you look at it.

You can set up Sendgrid as a Postfix or Sendmail relay host.
