How Smart SPF Works?

KDMARC is an industry-leading cybersecurity tool, designed to monitor three standard email authentication protocols- SPF, DKIM and DMARC, for complementing the Simple Mail Transfer Protocol (SMTP). It offers the Smart SPF feature to monitor and secure your email domains effortlessly. 

When you secure your email domain with KDMARC, it provides you with a Smart SPF record that includes all your previously configured SPF records, if any. To use the Smart SPF feature, you are required to replace any of your domain’s previous SPF records with the provided Smart SPF record on the DNS.

Once you have updated the Smart SPF record on the DNS, you can use the Smart SPF feature to configure your domain’s SPF record as needed on the KDMARC dashboard without going through the trouble of changing it manually on the DNS.

How to Use Smart SPF?

To use the Smart SPF feature, follow the steps given below:

Step 1: Go to the KDMARC Dashboard and select ‘Smart SPF’.


Step 2: From the drop-down menu, select the domain for which you wish to configure the SPF record.

There are a number of things you can do using the Smart SPF feature, such as:

  1. You can easily add records to your domain’s existing SPF record.
