Setting up Sendgrid SMTP Email in ERPNext

SMTP, or simple mail transfer protocol, is a quick and easy way to send email from one server to another. SendGrid provides an SMTP service that allows you to deliver your email via their server instead of your client or server. ERPNext comes built-in with a configured email client so that you can send and receive emails in ERPNext and append to documents if required.
