What is SMTP and why do you need it?
SMTP (Simple Mail Transfer Protocol) is the standard that ensures that emails actually arrive at their destination. It’s a protocol that delivers your email between servers when you click “send” in your email client.
You could say that with an SMTP plugin or service, you want to confirm to the email servers that what you’re sending isn’t spam, which lends authenticity to your mailings.
