brother i am sad that why didn't i found your video first, good work keep it up

I love you for this, man. Really saved my ass. I don't know why SMTP servers are so needlessly annoying to set up, but they really are. Your code is so much cleaner than basically all other solutions I found AND yours actually works straight away, no fuss. props, man.

Worth noting for others in the future, it didn't work in the emulator and I was lost for a while on why it wouldn't work, but for the sake of seeing if the emulator was causing issues, I loaded it on my phone and boom, the message was sent.
