Aaaaaand that's why I no longer use Amazon SES for transactional mail for signupforms.com. It is frequently used by mass-marketers, which means my transactional email was frequently being dropped by some email providers because of SES's poor deliverability.

Author here. I've noticed the opposite. All things being equal (email content/subject lines etc), my opens, clicks, etc.. all have increased since switching to SES. Not sure if an anomaly or what, but that's my experience.

Likewise, we tried SES and had far too many emails going to our customer's SPAM folders, so we switched back to Mailchimp/Mandrill.

I thought you could buy dedicated IPs for SES? Or is that not good enough to separate you from other SES senders?

This is true:

I've had zero problems with Sendy and SES on my platform over the past 2 years.

Are you sure SES was the problem? Did you correctly configured DKIM/SPF?

I've also had deliverability problems with SES, and I absolutely did set up DKIM/SPF right.

We've occasionally got bounces like "554 5.7.1 Service unavailable; Client host [54.240.27.56] blocked using dnsbl.sorbs.net".

Amazon say SORBS is worthless but unfortunately someone is still using them https://docs.aws.amazon.com/ses/latest/DeveloperGuide/blackl...

Seriously, doing bulk emailing you find that mail services are often the dustiest, cobwebbiest things on the internet. I swear some of these things have been sitting untouched for literal decades.

PostmarkApp. They only allow transactional emails and they have unbelieveable inbox rates.

I'm not affiliated with them, but might be their biggest fan.
