Which SMTP do you recommend? Is it best to use the AWS one or what are the other options?

From my past experience with AWS SES, it requires a bit more development to handle bounces, spam, etc. Perhaps at $previousjob, we did not have the resources to handle this development time.

Personally, I prefer Postmark. Their onboarding, support, and pricing is excellent. The interface is good and decent integrations.

Hey, author of the microservice here.

I work with AWS service since 2015. It's true that could be a little bit too much to use if you just want the email services (SES).

For small project I just go with mailgun because it just plug and play.
