Authenticating your sending domain confirms that Seguno is authorized to send email on your behalf. This improves deliverability and protects your brand by establishing a trusted sender reputation with inbox providers.
After authentication, Seguno automatically applies a domain warming process to help new or updated domains build credibility safely.
Authenticate a Google, GoDaddy, or IONOS domain (automatic)
Seguno uses Domain Connect to automatically add required DNS records for supported providers.
Steps to authenticate your domain using Domain Connect:
Open Seguno: Email Marketing.
Click Settings.
In the Sending section, click Authenticate your domain.
Click Connect automatically.
Sign in to your domain provider and approve the connection.
Click Close.
Seguno sends an email notification when domain authentication is complete.
Authenticate a Shopify-hosted domain
Shopify-hosted domains require manual DNS record entry in Shopify.
Steps to authenticate your Shopify-hosted domain:
Open Seguno: Email Marketing.
Click Settings.
In the Sending section, click Authenticate your domain.
Click Connect manually.
Leave the Seguno tab open and copy the displayed DNS records.

Click Domain settings → Edit DNS settings.
Click Add custom record.
Add the TXT record from Seguno.
Add the CNAME record from Seguno.

Note:
You may see an “Authentication failed” message while Shopify propagates DNS changes. Wait one to five minutes, then retry Authenticate domain.
