Roll your own with Amazon SES. Bang up a little script and call the CLI. for recipient in "${recipients[@]}"; do aws sesv2 send-email \ --from-email-address "$sender" \ --destination "ToAddresses=$recipient" \ --content "Simple={Subject={Data='$subject',Charset='UTF-8'},Body={Text={Data='$body',Charset='UTF-8'}}}" \ --region "$region" done I got that script from their website. Should be easy enough to knock something…

In my experience, it’s extremely difficult to get out of the SES sandbox, for what I presume is if your account/org is under a certain amount of spend with them. While basically free under a certain amount of usage, the gatekeeping there does make the idea of self-hosting your email free/cheaply sort of a nonstarter for indie devs. For context, getting out of the sandbox at every org I worked at was essentially a sin…

Is there a reliable solution we could use for our small startup? We want to shoot out daily emails to our users, like Bandcamp or Substack do. We could ofc use Mailchimp but always happy to explore self hosting. Would this or another solution work?

The biggest issue you will likely encounter is having clean IP addresses to send from. If you have that problem solved, the next hurdle will be realizing that Stalwart is more than you would need to manage sending daily emails. If you have the IP addresses, you could just use a script that grabs email addresses to send to for the day, and ship them with a fairly straightforward SMTP daemon (sendmail) installation on…

I've been using Postal Server for 2 years ( https://docs.postalserver.io/ ) sending around 50k emails / day without any issue. Just make sure you set up everything (SPF, DKIM, DMARC) correctly, including the PTR reverse lookup of your server ( really important ). Key tip: warm up your ip(s). I use mailreach.co ( it has a USD 25/m cost ), reached near 100% deliverability in a month. I now have barely have any maintena…

Thanks! Wdym by warm up your ips? How does mailreach relate to the setup?

Postal is not very well maintained, I don't think it's a wise choice to use it if alternatives exist.

Thanks! Any guide wrt using dkim / dmarc and such to ensure it's bulletproof? Any customizations you did beyond the CLI script above?

My entire script is here. https://gist.github.com/johnnydecimal/e7b1a03e26b79239363b5d... Though I've since updated that to include a .txt file as the body vs. typing it out in the email. But that's easy enough. I might have added TXT records to satisfy DKIM etc., I don't remember. There are guides on the Amazon site; I'm a bit of a dummy when it comes to this so if I worked it out it must have been obvious enough.
