SMTP relay is becoming more and more important each and every day that you are most likely hearing the term pop up every now and again, but what is it? SMTP stands for Simple Mail Transfer Protocol; in other words, it’s job is to relay and deliver your outgoing emails.

How does SMTP work?

SMTP is a lot simpler than it sounds and it is something that we ALL use every day. Each time you send an email, your mail service provider will connect to the configured SMTP server. In many cases, this will be the default local server and you won’t even need to think about it! However, many companies (small and large), especially those sending newsletters or transactional emails and in large volumes, will use an external SMTP provider when sending to their subscribers or clients. This means that they will configure their SMTP server to send via an external SMTP server, instead of their local default server.

What do we mean by relay?

Once the email has been sent, the SMTP server will transfer the email to the recipient’s incoming server; this is called ‘relaying’. Alongside the content, the SMTP server will relay the recipient’s address, the sender’s address, IP address, and timestamp.

How important is SMTP?

When sending emails on a one to one basis or in small volumes, you won’t need to worry too much about SMTP, you’ll usually be sending unique emails to different recipients, which won’t cause too many issues. However, when it comes to mass mailings for marketing purposes or transactional emails, it is necessary to use an external SMTP provider such as SMTP2GO to ensure that your emails reach those inboxes. If you continued to use your default local SMTP server, not only would you run into a number of ISP sending limits, your email delivery stats would significantly suffer, alongside clogging your bandwidth and potentially delaying the sending of one to one emails. Sending emails is not as simple as we once thought and it takes a lot of time, money and know-how to do it well.
