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.
- Your emails keep landing in spam. A verified domain builds sender reputation and improves inbox placement.
- Recipients see a generic sending address. Authentication puts your own domain on every outgoing email, so contacts recognize you.
- You need to prove you own the domain you send from. The DNS records confirm ownership and let providers trust your mail.
Example Use Cases
- A sales rep sends follow-up emails from their company domain so prospects recognize the sender.
- A marketing manager authenticates the domain before a campaign to keep bulk emails out of spam folders.
- An account admin verifies a new domain after a rebrand so all outgoing mail carries the current company name.
