Clustered Networks - How to Check your Domain Email Flow

If you are having problems with your Email Flow, this is a quick quide to help you to take a look at some of the issues that may be causing the email that you send out to get get caught in the recipient's Spam Folders. This is a common problem today as world is bombbarded with security breaches and hack attempts. In order to make sure your Email is Flowing properly you want to make sure your have your Domain DNS settings setup properly. This includes having no errors in your MX / DKIM / SPF and DMARC records.

1. Check your MX / DKIM / SPF / DMARC settings.

There are various Tools you can use to see if your Domain settings are set properly on the Internet. If you are using Google Workspace a good place to start is The "Google Admin Toolbox". If you have any errors you can adjust them until they are all set properly. If you are unsure of what to change to make your email work properly, we at Clustered Networks can help you out.

2. Send Email to Yourself

This sounds kind of silly, but you have to do it. Send an email from your Domain to yourself at a free email account you create on Gmail or Protonmail or something similar. Then check your email on the free account and trace the route it took by examining the headers. Don't just look at the message but the "message headers". If you have trouble reading the message headers, cut and paste the headers into a message header analyzer like at MXToolbox. By doing this you will know the route the message took and can determine if any servers along the way are on blacklists or are configured properly.

3. Check for Blacklisting

This can include checking both your Domain for Blacklists as well as any of the IP Addresses in your DNS SPF Record. For example, If you are using Google Workspace for your Email check to see if the IP Blocks are Blacklisted. As well you could be using other third party senders to send mail on your behalf such as Sendgrid, Mailgun, Mailjet or some other SMTP sending service. IF you find the SMTP service your are using is having a problem with blacklists, you may have to switch to a different service.

4. Check the Spammyness of the Emails your send.

Once you have all of your settings adjusted properly we also recommend your check your Spam Assassin Score to see if there are any issues with the spammyness of your emails. All Mail Servers that receive email have some sort of Spam Filter Software that they use. One of the most popular is Spam Assassin. By using the link below your can check your Spam Assassing Score by sending and email and then looking at the score of your email message. It is very simple to do and the results are obtained in a few seconds.
