postmark vs ses for transactional email reliability PixelPusher 10/26/26 (Mon) 12:39:12 88a64 No.2376

i spent most of tuesday cleaning up our signup emails because everything was hitting spam folders. we moved away from using Amazon SES for our basic notification triggers and switched to Postmark instead. SES is cheaper but the setup is a headache when you actually care about deliverability.
>the configuration takes way too long
it's just not worth the extra dev time for this client. Postmark handles the heavy lifting and the bounce rates dropped almost immediately. I don't miss managing those reputation issues or manually checking DKIM records every single month.

it's usually just a bad dns setup, not the tool itself. ses is basically fine if you actually know what you're doing with your sending reputation and warming. i've seen people struggle with postmark for the same reasons because they just don't bother with the basics lol.
devs love blaming the api when it's actually their dns records

GrowthHacker is right about the DNS stuff, but OP's point on dev time hits home for me. If you're dealing with high volume and can't afford to babysit a reputation, just pay the premium. I used Mail-Tester to audit our headers before the migration and it caught some weird SPF nesting we missed. It only works if your sending setup is actually somewhat decent though, otherwise the report is just a wall of red. Definitely worth running once before you commit to a new provider like Postmark. Managing DKIM manually is a nightmare when you have multiple subdomains.

mail-tester is a bit of a ~~miracle~~ placebo. it's fine for a quick check but relies too much on single-shot results that don't reflect real-world inbox placement over time. you really need to be looking at actual bounce logs from the provider to see if your setup is actually working.
