Custom Sender Domains

Common questions about sending Zigpoll email surveys from your own domain.

A custom sender domain lets your email surveys go out from your own domain (e.g. [e-mail]) instead of the default [e-mail]. This improves brand recognition and deliverability. Here are the questions we hear most often.

What plan do I need?

Custom sender domains are available on the Standard plan and higher. If the feature is locked, you'll be prompted to upgrade.

What domain should I enter?

Use a dedicated subdomain for sending, such as mg.yourstore.com — not your root domain. This keeps your sending reputation isolated and avoids conflicts with your main domain's existing email records.

What DNS records do I need to add?

After you save your sending subdomain, Zigpoll generates the SPF and DKIM records (added as TXT records) that authorize Zigpoll to send on your behalf. The exact Name and Value for each record are shown in the dashboard — add them in your DNS provider exactly as displayed.

Can Zigpoll add the records for me?

Yes. For supported DNS providers, click Auto-Connect DNS and Zigpoll adds the records automatically in one click. Otherwise, copy each record's Name and Value into your DNS provider manually. Every record shows a live status (unverified / valid / invalid) so you can confirm it landed correctly.

How long until my domain is active?

Once the records are in place, click Verify Domain. As soon as they validate, your sender domain activates automatically — there's no manual approval step. DNS changes can take up to 24–48 hours to propagate, so if the records still show as unverified, wait a little and verify again.

What address will my surveys come from?

Your survey emails will be sent from [e-mail] (based on the root of your sending subdomain). If you set a Reply-To address on that same domain in your email design settings, replies are routed there.

My domain won't verify — what should I check?

• Confirm each TXT record's Name and Value match what's shown in Zigpoll exactly (no extra spaces, no missing characters).

• Make sure you didn't alter or split the long DKIM value when pasting it.

• Allow time for propagation, then click Verify Domain again. You can check propagation at dnschecker.org.

• If the records verify but setup doesn't complete on its own, use the Retry Setup button — or reach out to us if it persists.

How is this different from a custom survey domain?

A custom sender domain controls the address emails are sent from. A custom survey domain controls the URL customers visit to take the survey. They're independent — set up both for a fully white-labeled experience.
