I'm looking for an email (outgoing only) provider that has an API. I'd be sending probably ~100 a month, maybe. The reason is because microcontrollers have a hard time with TLS and whatnot, but CURLing to an API isn't that big of a deal.

I know sendgrid offers something like this as a freemium service, but free services sometimes don't work well. Is there a service that has a very limited, cheap plan but would still offer some support if needed?

I use C# and it talks to any smtp server. It has authentication too. There are a ton of options.

Many uCs don't have the memory or performance to do TLS. His shortcut is to want a REST API which relays for him.

Personally I believe something like mqtt to his own server which then relays is a better option.

I'm limited to arduino c++ for this project.
