Maybe it’s a bit off-topic, but for my transactional emails, I use Scaleway TEM’s free tier. 300 mails/month are included, if you go above, it’s 0.25€ per 1000 mails. Dirt cheap. Never have I gone above the free tier limit. And it saves me from the hassle to have to setup something to send emails on thr server itself. Note that I had strange behavior while I tried to validate my domain while I used CloudFlare’s nameservers.
