The settings below are made by your domain name provider. If you are sending email campaigns/mailings from multiple domains, follow these steps for each domain. 

If you are not sure how to set it up with your domain name provider, contact them for guidance. 

To set the DKIM:

DKIM stands for "DomainKeys Identified Mail" and is an email authentication technique that verifies that a message was sent from a legitimate user of an email address. It is designed to prevent e-spoofing or spoofing (communication sent from an unknown source that is disguised as a source known to the recipient).

Rule supports DKIM and to set it up you need to add a CNAME.

A Canonical Name record (abbreviated CNAME record) is a type of resource record in the domain name system (DNS) that is used to indicate that a domain name is an alias for another domain (the canonical domain) in your DNS. 

The following is added: pointing to =your domain, for example.

See here:

1. Click "Add subdomain" and fill in: Subdomain: keyse._domainkey

2. Select CNAME and then Data:

To set DMARC:

Domain-based Message Authentication, Reporting and Conformance (DMARC) is another way to verify incoming mail by authenticating the sender's domain. DMARC is especially important for mail sent to Outlook/Hotmail.

  1. Log in to your DNS and select the domain name that you want to use as the sender.
  2. Click DNS Editor.
  3. Click "Add Record".
  4. Select the type "TXT"
    TTL (Time to live) determines how often the value is checked in seconds, the default is 3600 and it is just fine.
  5. In the name box, add the following value: _dmarc
  6. In the data box, add the following: v=DMARC1; p=none;;
