DKIM uses a combination of public and private keys to sign and verify email messages. When an email message is sent, the sender's mail server adds a digital signature to the message using a private key. This signature is a unique code that is generated using a mathematical algorithm, and it is based on the contents of the message.

When the recipient receives the email message, their mail server uses the sender's public key to verify the signature and ensure that the message has not been altered in any way. If the signature is valid, the recipient can be confident that the message is authentic and came from the sender.

You must set up custom DomainKeys Identified Mail (DKIM) authentication for your domains. It will ensure your emails reach your recipients’ inboxes and they will appear as sent through your branded emails and not from AiTrillion emails.

• GoDaddy
• Shopify
• Google

It is a form of email authentication that allows an organization to claim responsibility for a message in a way that can be validated by the recipient.

Note:  Please remember that to configure DKIM, you need to have a professional email service (e.g. yourname@yourwebsiteurl.com ). Free email services provided by Gmail / Yahoo / Microsoft etc will not work, even if one of these is used by your business for professional purposes.

Workflow

You can set up the DKIM settings in the app by following the below steps:

Step 1.  Login to AiTrillion.

Step 2. Go to the DKIM Settings page under email marketing and settings.

 

Step 3. A page will appear, fill in the details, and click on the  Save button.

 

Then a popup will appear with the below details, you need to do these CNAME entries in your domain hosting provider account.
