How to Set Up DKIM for UniSender?

October 11, 2023  |  2 min read

DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with. 

Steps to Configure DKIM for UniSender

  • Sign in to your UniSender account, and select on the profile icon
  • Click “Account Setup” from the list
  • Select “Domain Authentication” on the Account Setup page.

Note: Before configuring DNS records for email authentication, you must first add any confirmed emails that are missing from UniSender. To do this, select the “Confirmed Emails” tab, click the +Add button, and then enter your email addresses.

  • Select “Create” under the Domain Authentication tab.

  • Simply select “Obtain Settings”
  • You may locate your DKIM DNS record here.
  • Depending on the DNS hosting company you use, the process for publishing the record on your domain’s DNS will vary. Please choose the TXT resource type, provide your hostname in the Host/Name/Hostname field, and leave the TTL at “1 hour” or the default value. Save your record, then permit 48–72 hours for the modifications to take effect on your DNS.
