How to Authenticate Your Sending Domain?

 

Domain Authentication lets you send emails from your own domain instead of a default BIGContacts sending address, which improves deliverability and keeps your brand on every message. You set it up from the Domain Authentication card under Admin › My Account.

 

What Is Domain Authentication?

 

Domain Authentication is a BIGContacts setting that connects your own domain as the sending source for outgoing emails. It lives in the Domain Authentication card under Admin › My Account, and it works by adding a set of DNS records that prove you own the domain. Once those records are verified, BIGContacts sends emails from your domain instead of a shared default address.

 

Why Use It?

 

Authenticating your domain changes how recipients and inbox providers treat your emails.

 

Example Use Cases

 

Step-by-Step Instructions

 

Step 1: Go to Admin in the left navigation, then open My Account.

 

Step 2: Click the Domain Authentication card.

 

Step 3: Enter your domain in the Domain Name field on the Connect your sending domain screen.

Note: Enter the domain only, without www or https:// — for example, proprofs.com.

 

Step 4: Copy each DNS record from the table while the status shows DNS Verification Pending.

 

Step 5: Add the copied records at your domain provider, then return to BIGContacts and click Verify Domain

 

Step 6: Confirm the status changes to Active with a Domain Verified message.

 

Pro Tips & Interactive Settings

 

Tip: After a domain is verified, use View DNS Records to review the records at any time, and Remove Domain to disconnect a domain you no longer send from.
Settings: A verified domain shows an Active status; a domain waiting on DNS shows DNS Verification Pending until all records resolve. Records include one TXT (SPF), three CNAME (DKIM and tracking), and two MX rows.
