To help us ensure that emails sent by the Limelight Platform are not marked as spam, we need to verify your sending domains. A sending domain is an email domain that you intend to use as your email’s ‘from address’. For example, if your email was from, the sending domain would be

Limelight is committed to the high deliverability of email messages, as such, we are requiring DKIM (Domain Keys Identified Mail) to be configured for all sending domains. To configure the DKIM, your Ops team will need to make updates to your sending domains’ DNS records. They’ll most likely know what this means, but if they don’t, do not hesitate to reach out to your Customer Success representative to get further assistance.

What are the steps to take?

The exact steps to configure DKIM varies by your domain hosting provider, but the general instructions are as follows:

  1. Provide the email domain you intend to use to your Client Services representative.
  2. They will send you an Email Set Up PDF for you to give to your Ops team.
  3. Contact your Ops team and provide them with the DKIM + SPF information.
  4. Have them add TXT records to your Domains for your DKIM records.
  5. Once they have added the TXT records, inform your Client Services representative.
  6. Limelight will then verify the setup in the mail sub-system and either inform you of the successful configuration or help you to troubleshoot if the verification has failed.
