I need to send email with same content to 1 million users.
Is there any way to do so by writing script or something?
Email Id's are stored in Excel format.
It is absolutely possible for a bot to be made that creates gmail accounts, in fact many already exist. The main problem is how to solve the captcha that is required for each new account, however there are services already built to handle this. The only problem then is being willing to violate googles terms of services, as I'm sure this does in one way or another.
