For those recommending against SES for critical deliveries, what are you using?

In the recent past I’ve used Postmark, but they were acquired by a marketing company.

For any critical email delivery make sure you can address this thing with the mailsender of choise:

1)SPF,

2)DKIM,

3)DMARC [2] (DMARC is often forgotten or can be super noisy when set up. Postmarc offers a aggregation service for free that sends you a weekly summary),

4)Dedicated IP

5)Reverse IP look up [1] (locate a dns PTR record for that IP address) should match the sender.

Not everyone supports 5).

4 and 5 is what you end up paying for, but totally worth it. Sendgrid, SES, Mailgun etc.

And 1 surprising thing (to me) is some places (iCloud was what bit me) alway want you to be able to receive email (have MX records). Even though I have no need to support incoming emails iCloud was blocking my sending until I got that setup. The incoming emails just go to a black hole but that's enough.

Shameless plug: I've recently started my own transactional email service (https://www.markix.com), primarily targeting small senders, after having been a very happy Postmark customer for a long time. Our service is still in closed beta but delivering live emails.

I run a couple other businesses and moved all of my transactional email sending over to Markix.

Would love to have a chat with anyone that might be starting a new project and is open to try out a new mail service (mail in bio).
