Make your emails more trustworthy with DKIM

September 3, 2025

DKIM (DomainKeys Identified Mail) adds a digital signature to every email you send so inbox providers can confirm it really came from your domain – and hasn’t been altered in transit. That extra layer of trust keeps your messages out of spam folders.

Automatic Authentication

Gigahost automatically configures SPF, DKIM and DMARC and signs every outgoing email for you. No extra setup is required; your messages are authenticated from day one.

How to Verify or Activate in Control Center

1. Log in to the Gigahost Control Center and select your domain.

2. Click DNS in the top navigation.

3. Under TXT records you’ll see a DKIM entry beginning with v=DKIM1;….

   • If it’s there, DKIM is active and signing your mail.

   • If it’s missing, scroll to DNS Templates and add the “Gigahost DKIM protection” configuration.

Quick Tip

You can also check that the Gigahost SPF protection template is applied — but only enable if no other providers send mail for that domain.
