Why add a custom sender email?
By default, Subi sends subscription notifications from a Subi-provided address. If you’d like these emails to come from your own domain (for example, [email protected]), you can set up and verify a custom sender email in your Subi settings.
Steps to add a custom domain sender email
1. Go to Notifications in Subi settings
In your Subi dashboard, open Settings > Notifications.
Under Customer notifications, click Add custom email.
2. Enter your custom email address
A modal will open.
Enter the address you’d like to use (for example,
[email protected]).Click Add.
3. Verify your email configuration
Your new email will appear in the list with an Unverified badge.
Click Verify configuration next to it.
4. Add CNAME records in your domain provider
A modal will show 3 required CNAME records with host names and values.
Log in to your domain provider (e.g., GoDaddy, Cloudflare, etc.) and open your DNS management.
Create a new CNAME record for each entry:
Copy the Name and paste it into the record’s Name/Host field.
Copy the Value and paste it into the record’s Value/Target field.
Save your changes.
Note: Some domain providers require you to only enter the first part of the Name field.
For example:
Enter
em9625instead ofem9625.yourdomain.comEnter
s1._domainkeyinstead ofs1._domainkey.yourdomain.com
5. Authenticate your domain in Subi
Return to Subi and click Authenticate again.
If the DNS records are correct, your domain will be verified.
6. Use your verified custom email
Once verified, your email will show a Verified badge.
Select it as the sender for subscription notifications.
You can also edit, view configuration, or remove the email by clicking the three-dot menu.
Important notes
Verification is handled through your domain provider. While it often completes within minutes, it may take up to 48 hours.
If your email still shows as Unverified after 48 hours, double-check your DNS records. If issues persist, contact Subi support for assistance.
Next steps
If you run into issues with DNS setup, reach out to your domain provider for guidance.
