Email Domain

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 high deliverability of email messages, as such, we are requiring both DKIM (Domain Keys Identified Mail) and SPF (Sender Policy Framework) to be configured for all sending domains. To configure DKIM and SPF, 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 and SPF varies by your domain hosting provider, but the general instructions are as follows:

  1. Provide the email domain you intend to use to your Customer Success representative.
  2. Limelight will provide a document like the one attached to give to your Ops team.
  3. Contact your Ops team and provide them with the DKIM and SPF information for your domain(s) below.
  4. Have them add TXT records to your Domains for both the SPF and DKIM records.
  5. Once they have added the TXT records, inform your Customer Success 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.
