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 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.
SES is pretty solid and easy to work with. Free for small email volumes like your use case.
You need to verify your domain and request production access explaining your use-case. If you’re only sending to known recipients, you can just verify them and not worry about the “production access”.
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.
I am in the exact same boat. I just switched to Proton as it looked like they had these features right away. But it turns out you have to explain what you want to use smtp for before they allow you to generate tokens. Which is probably due to them attracting a high amount of scammers due to their really good privacy. So I can understand but it is a tad annoying. If you are willing to wait I’d give them a try. Their business plan is cheaper than googles and gives you a lot and they are open source.
Good to know, thank you. I looked into proton for my primary mail account, but I didn’t think of it for that purpose.
Nevermind. After days of back and forth with them they said that they only have that feature available to big companies that have an account with them for a year or more, which is definitely annoying. I’m going to give Brevo a shot next, I heard someone mention them in a thread before about this. It looks like their free tier allows for 300 emails a day. I’ll let you know how that goes if you are still looking.
I use mailgun at the moment. Still free for me and I send 2-3 mails per day. I had problems once with some mails not arriving or landing in spam, but that was fixed after a day or so.
Edit: Just checked the dashboard and I’m getting 1000 mails per month for free. Can’t find exactly where they offer this plan anymore though, so they might have removed that.
Was signed up there as well, when they started like years ago. But I couldn’t get back into their free tier.
