Enabling DKIM signing for your domains can help you keep your email content intact throughout the delivery process, barring threat actors from accessing and altering your emails. This helps preserve your identity and eradicate spam and phishing attacks.
Here are the steps to setup DKIM for Sender
Sender has developed a tool that automatically generates the DKIM. You can see both SPF and DKIM values in the “Domains” branch of the “Settings”.
Alternatively, if you are using your own servers to send emails instead of Sender’s, you can generate your DKIM key pair using our free DKIM record generator tool.
Login to the Sender Console
Click on Settings.
Now click on Domains
A small screen will appear
Click on Check SPF/DKIM records
Save changes to your record and wait for 48-72 hours for your DNS to process these changes.
