Using a Custom Domain for Email Distribution

If you would like to use your own domain for email distribution (instead of @staffino.com), the following setup is required to ensure successful email delivery via Mandrill.

Sending Domains Overview

All emails sent through Mandrill must use verified sending domains with correct DKIM and DMARC DNS records for authentication. Emails from unverified or misconfigured domains will be rejected.
To proceed, please provide us with your domain URL, and ensure the following DNS records are added.

DKIM Configuration

DKIM (DomainKeys Identified Mail) is an authentication method that verifies Mandrill is authorised to send emails on your behalf. This helps improve deliverability and protects against spoofing.

To configure DKIM, add the following two CNAME records to your domain’s DNS settings:

After saving the records, click “Test DNS Settings” to verify the setup.

DMARC Configuration

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a policy framework designed to combat email spoofing and phishing.
As of 2024, Mandrill requires a minimum DMARC policy of: v=DMARC1; p=none

To configure DMARC, add a TXT record to your domain’s DNS settings with the following details:

Once the record is saved, use “Test DNS Settings” to confirm the configuration.

Note: Some DNS providers automatically append your domain name to the record. If you’re unsure how to format the host field correctly, please consult your domain provider.
