SMTP Cheat Sheet

Make Your Email Work for You

Clients are consistently confused about how to set up their SMTP, and it’s a shame because there’s no one answer. Your SMTP settings depend on a variety of factors, but we want to make it easy for you to get the information you need.

If you’re confused about how to send and receive mail, look no further. SMTP is the way that your electronic mail is transmitted away from your computer or phone to the recipient’s computer or phone.

SMTP is handled differently by different ISPs

You have to make sure you properly set up SMTP on your phone or computer. Whenever we set up an email for you, we can handle all the receiving stuff, but you have to make sure that you apply the proper settings so that you can send mail out based on your Internet provider and/or your mail provider. In some cases, your Internet provider may also be your email provider.

Get Set Up

To get set up, you’ll want to check your mail provider (Gmail, Outlook, AOL, etc.) and look for their SMTP settings. Once you have those settings in hand, you can accurately set up your email account to send and receive mail.

If you’re still having trouble setting up your SMTP, double check that the port you’re using is correct. Then, if you’re still having problems, contact your email provider for support. And remember, if you’re going through a different third-party server than the ones listed above, make sure you check out their website or service page for information on how to set up your SMTP.

Spam Issues

If you’re receiving a lot of spam, you may want to double check the port that you’re using. Port 25 is not very secure, and many providers block this port for security reasons. If you set up your mail but you still aren’t able to send outgoing messages, you may need to make sure that, if you’re using port 25, it’s allowed. If not, you’ll need to check with your provider to see if there are other port options available.
