Connecting Your Domain and Verifying Sender Emails

Connecting your domain and verifying sender emails in Zoho Marketing Automation improves email deliverability and confirms to mailbox providers that your campaigns genuinely come from you. This article walks through the process.

Before you start

You will need access to your domain’s DNS settings, either directly or through whoever manages your hosting or domain registrar.

How to authenticate your domain and verify sender emails

1. Go to Settings > Marketing Channels > Email and open the Senders and Authentication tab.
2. Click Add Sender, enter the sender email address you want to use, and click Save.
3. Open the verification email Zoho sends to that address and confirm it.
4. Back in Senders and Authentication, find your domain and click Setup to reveal the SPF and DKIM TXT record values.
5. Log in to your domain host (for example GoDaddy, Cloudflare or your website provider) and add these TXT records to your DNS settings. If you already have an SPF record, add include:zcsend.net to it rather than creating a second one.
6. Save the DNS changes and allow up to 24 to 48 hours for them to take effect.
7. Return to Settings > Marketing Channels > Email, click Setup next to your domain, then click Authenticate.

Zoho confirms whether authentication succeeded, or shows guidance if something needs correcting.

Why this matters

SPF tells mailbox providers which servers are allowed to send email for your domain, and DKIM adds a digital signature to confirm messages have not been tampered with. Together they reduce the chance of your campaigns being flagged as spam.

Frequently asked questions

Why does DNS take time to update?

DNS changes can take up to 24 to 48 hours to propagate, so authentication may not succeed immediately.

What if I already have an SPF record?

Add include:zcsend.net to your existing SPF record rather than creating a second one, since a domain should have only one SPF record.

What happens if I do not authenticate my domain?

Unauthenticated emails are more likely to be marked as spam or blocked by mailbox providers, which reduces deliverability.
