GAE is not run on the local server, you have to configure SMTP locally and invoked their methods
Steps:
Install SMTP locally (https://www.gazblog.com/2016/07/install-ssmtp-and-setup-with-gmail-on-ubuntu-16-04/)
Add this code to send the mail (https://medium.com/@dhanushgopinath/sending-html-emails-using-templates-in-golang-9e953ca32f3d)
