Sending emails from your own domain is essential for brand consistency and higher email deliverability. Zonka Feedback allows you to authenticate your email address so that feedback requests, survey invitations, and notifications sent from the platform appear as if they are sent directly from your organization’s domain.
By setting up Sender Authentication, also referred to as White Labeling your Email Domain, Zonka Feedback becomes a trusted sender for your domain, ensuring better inbox placement, preventing emails from going to spam, and offering a fully branded experience.

What is Sender Authentication and why it's important
Sender Authentication allows you to send emails via Zonka Feedback using your own domain (e.g., feedback@yourcompany.com) rather than Zonka Feedback’s default mail domain.
It improves email deliverability by establishing trust between your domain and receiving email servers.
Prevents your emails from landing in spam folders, enhances your brand visibility, and ensures a seamless user experience.
It is a must-have for customer-facing emails like NPS, CSAT, and CES surveys sent post-transaction or service.
Steps to authenticate your domain in Zonka Feedback
To start sending emails from your domain, follow these steps:
Go to Settings > Email Surveys in your Zonka Feedback account.
Click on Sender Authentication
Enter the domain you'd like to authenticate (e.g., yourcompany.com) and click on 'Add Domain' Click on “Add Domain” and enter the domain you wish to authenticate.
Zonka Feedback will generate the necessary DNS records (SPF, DKIM, and CNAME) that need to be added to your domain’s DNS manager.
Share the generated records with your IT/Admin team or access your domain registrar to add them manually.
DNS Records to configure
You will receive 3–5 records, including the following types:
SPF (Sender Policy Framework): Ensures that only authorized servers can send emails from your domain.
DKIM (DomainKeys Identified Mail): Digitally signs your emails so the recipient knows it was genuinely sent by your domain.
CNAME Records: Used for tracking and branding the email links (like survey links).
📌 Important Notes:
You must add all provided DNS records exactly as shown.
Changes in DNS can take up to 24–48 hours to propagate.
SPF and DKIM are essential for authentication; CNAME is for white-labeled tracking links.
Verifying Domain Authentication
After DNS records are added:
Return to Email Settings in Zonka Feedback.
Click “Verify Domain” next to your added domain.
Zonka Feedback will check the DNS records.
If all records are configured correctly, the status will change to “Verified”.
Once verified:
You can start sending surveys and notifications using your domain.
Emails will now show your domain in the “From” address (e.g., feedback@yourcompany.com).

Frequently Asked Questions
Can I authenticate multiple domains?
No. At the moment, Zonka Feedback supports authenticating only one domain per account. However, within that domain, you can use multiple email addresses (e.g., feedback@yourcompany.com, surveys@yourcompany.com, support@yourcompany.com).
How does email authentication work technically, and does it affect my existing emails?
Technically, when you authenticate your domain, you are adding specific records (SPF, DKIM, CNAME) to your DNS:
SPF ensures that Zonka Feedback is an authorized sender for your domain.
DKIM signs emails to verify their authenticity.
CNAME enables link tracking under your domain.
💡 This process only authorizes Zonka Feedback to send emails on behalf of your domain. It does not affect your existing email providers like Google Workspace, Microsoft 365, or others. Your regular email sending and receiving operations remain completely unaffected.
How do I add the DNS records if I use Google Domains, Google Workspace, or Cloudflare?
For Google Domains/Google Workspace:
Go to Google Admin Console DNS > Apps > Google Workspace > Gmail > Authenticate email.
Navigate to your domain's DNS provider or stay within Google Domains.
Add the TXT, CNAME, and other records as provided by Zonka Feedback in the domain's DNS management section.
Save changes and wait for DNS propagation (usually 15 mins to 48 hours).
For Cloudflare:
Log in to Cloudflare.
Choose your domain from the dashboard.
Go to the DNS tab.
Click Add Record and choose the appropriate type (TXT, CNAME).
Copy and paste the Host/Name and Value fields exactly as shown in Zonka Feedback.
Click Save and allow propagation time.
📌 Be sure Proxy status is set to “DNS Only” for CNAMEs when using Cloudflare.
