To prevent email impersonation and ensure delivery, Sirvoy checks the sender authentication policy of your email address found at Settings -> Your Account -> Contact Details.

Sirvoy will check for:

  • Domain-based Message Authentication, Reporting, & Conformance (DMARC)
  • DomainKeys Identified Mail (DKIM). 

Regardless of your domain’s DMARC/DKIM setup, your messages will be delivered. Sirvoy will use its address to send your emails to guests as needed.


  • Applies to custom email domains, not major email providers (Gmail, Yahoo, etc.).
  • Contact your webmaster or web host support for help.

Verification Setups


  1. Go to your domain’s control panel.
  2. Set up DMARC per preference.
    • If the DMARC policy is “none,” DKIM is not required for sending emails from your address.
    • For “quarantine” or “reject,” DKIM is required for sending emails from your address.
  3. In Sirvoy, go to Settings -> Your Account -> Contact Details to auto-detect DMARC. 
    • All future emails will use your custom domain after passing the check.

DKIM Setup

  1. Request a DKIM key from
    • Include your Sirvoy Account ID and domain name.
  2. Add the key to your DNS server.
  3. Contact Sirvoy support to enable the DKIM key.
