Domain authentication shows email providers that Lead Docket has your permission to send emails on your behalf. To give Lead Docket permission, you point DNS entries from your DNS provider (like GoDaddy, Rackspace, or Cloudflare) to Lead Docket. Your recipients will no longer see the “via leaddocket.com” message on your emails.
Even though this is a small change from your recipients' perspective, this change has a huge positive impact on your reputation as a sender and your email deliverability. Email service providers distrust messages that don't have domain authentication set up because they cannot be sure that the message comes from you. Explicitly stating that it comes from you increases your reputation with email service providers which makes it much less likely that they will filter your mail and not allow it get to your recipient's inbox, which increases your deliverability. You are also explicitly showing your recipients that this email comes from you, so they are less likely to mark your mail as spam.
To enable this on your domain, you will need to add 3 CNAME records to your DNS as follows:
Once these DNS entries are in place, please contact Lead Docket support at email@example.com and ask them to verify the DNS entries are in place to enable sending domain authenticated emails.
