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).

    I know this doesn’t fit your criterea OP, but if anyone else is looking for some kind of notification service, I use: SMTP to Telegram

    I get instantly notified on my phone for healthchecks.io failures, cronjob reports for different scripts like borg backups or ddns update failures, certain Home Assistant scripts, and Sonarr completions so I know when a new TV episode is done downloading, and a bunch of other things set to notify on failure like SMART failures or snapraid-runner failures or distro updates… so many things. It’s nice having peace of mind that if I haven’t been notified that something is wrong, then I know everything is working, and I do not need to check on it. So it’s one of my favorite services that I’m running.

    I don’t think I need to say it, but this is obviously not something you would put facing WAN as there is no TLS nor authentication.
