I have managed to send emails using SMTP2go on my Arduino Mega 2560 and am about to put that project in its operating location and start working on the next one.
I find smtp2go rather restrictive, especially in the development phase. A coding bug sent out 900 emails back to back to the same address and they blocked me until the end of the month. I don't need that type of stress in my life anymore.
Multiple posts say that the Mega 2560 just doesn't have the oomph to manage TLS.
How about the Due, or the Yun. Would those work to send Gmail based mails?
Any other options, I should consider?
I have a few ESP8266 NodeMCU CP2102 ESP-12E hanging around too.
Any suggestions would be welcome.
Have a great and safe week.
