Hi Kyle 
This is wrong
"The Gmail SMTP server is smtp@gmail.com, and the use-IP sender SMTP port is 465 (for SSL encryption) and 587 (for TLS encryption) – if you are not given the option to use either SSL or TLS, then both port numbers should work fine."
We do not use the @ sign when specifying SMTP.
