Hi there,
what SMTP relay’s / services do you use or can recommend for sending monitoring alerts.
I’m running a few services, but mostly all my custom scripts, and tasks are configured to sent an e-mail if something goes “off-script”. Before I used my gmail account - but I’m in the middle of migrating away, and my requirements have evolved.
I’ve searched but I haven’t found anything good. Services like Mailgun, Mailtrap etc. are nice - but their bundle’s are a bit much for my taste.
The service/ relay should meet the following requirements.
- bring your own domain (use your own domain/ or sub-domains as sender address)
- must have DKIM (anything else is not a serious service!)
- support SMTP via TLS
- support multiple SMTP clients, with each different credentials/ secrets
- Allow custom header/ envelope changes
At the moment I’m looking at Amazon SES, because I don’t expect a lot of messages (I had 3 alerts in the last 1,5 yrs).
A little note on that: Amazon SES free tier is going to change starting tomorrow though. It changed from free to free for 12 months (with adjusted limits), see https://devclass.com/2023/06/23/aws-to-remove-62000-message-simple-email-service-always-free-tier-from-august-2023/
After the pricing change, I believe it’s still free (or negligible) for low email traffic.
5,000 emails per month are still free, at $0.07 per 1,000 after that.
