Trust me, I’ve done everything. Life is not fair if you want to send transactional emails with a very limited budget to people beholden to the monopolies.

Don’t give up… sometimes it can take them a while to sort it out.
You could also enlist the help of your users… ask them to contact the support dept of their email provider and ask why their emails are being ‘censored’! We’ve had to do this on a few occasions in the past!

Highly recommend Postmark. They only do email and they do it very well. Excellent dashboard that lets you get answers when you’re under a time crunch. Used others in the past but Postmark is by far the nicest.
Also, they guide you through getting it properly set up with DKIM and Return-Path. Removed a lot of the guesswork for me. Working at a startup I’m juggling a million things at once and Postmark just brought me joy and respite – not more problems.

Sure, I agree it’s an arms race but what recourse do we have? We best just migrate to the service du jour that works today. Not like I disagree with you, I am simply being pragmatic.

At work, we’ve decided to use a dedicated IP on SendGrid to avoid the same situation you described.
If you decide to go this way, you would have to authenticate your domain.

Sorry, to clarify, I meant a dedicated IP on one of the services rather than hosting your own. It sounded like that was not what you were looking for from a budgeting standpoint though.

This isn’t a solution for your SendGrid problem, just an anecdote.
When SES shut us down a few years back without explanation, appeal, or recourse, I moved over to Sparkpost which has been reliable for the last several years.

I’ll put another vote behind Postmark. They have been great for me (though my usage was on the smaller side).
I’ve even contributed to the Elixir Swoosh library to help integrate Postmark’s broadcast email services:
I’d also recommend their resources as a general source for great info on email things regardless of provider.
Good luck!

I have an app that needs to send an occasional transactional email and also sends a newsletter for parents of school kids. Postmark docs were really useful for doing a proper setup (have two domains for transactional and non-transactional emails). I really enjoy their service and I feel like I’m getting my money’s worth.

Yeah I had so much trouble with sendgrid and outlook, even with a dedicated IP. They eventually admitted the IP i was using was burned and changed it, but their support was so useless. Calmed down and still with them, but if I ever get a spare moment I’m ditching for postmark.
