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’ve been using SMTP2Go at work for our low volume of notifications and it works fantastic
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.
Even if it’s a bit different. It’s always nice to see what’s out there. I will definitively look into it.
I use Purelymail for mine. I have Uptime Kuma integrated with it using the SMTP server and also have different things like my password vault connected through it. It’s generally lightning fast and budget friendly too.
It sounds very promising.
Thanks. I really appreciate all those “niche” products. With just web research I wouldn’t have found it.
I use mailrise which is apprise under the hood for anything that doesn’t have Pushover support built into it. Mailrise converts any email it receives to a push message. It supports a ton of different services like Pushover.
