I am testing Mailtrap last weeks. You can send emails from your domain for free. They allow 1000 mails/month. It is quite ok. It can be used with good old SMTP connection or via API. https://mailtrap.io/

Came across a nice test SMTP server at @Mailtrap today. Seems like a lovely little service to use, free plan and price plans are very reasonable. No more dev junk in my mailbox 🙂
