Zoho SMTP Account Approval
Complete requirements and steps to get your Zoho ZeptoMail account approved for sending transactional emails.
Domain Ownership & DNS Setup
Authenticate the domain you will send emails from by adding required DNS records.
Why DNS records matter: These records prove you control the domain and allow recipient servers to trust your emails.
Domain Verification in ZeptoMail
| Step | Action | Details |
|---|---|---|
| 1 | Add Domain | Go to Domains section in ZeptoMail and add your domain |
| 2 | Copy DNS Values | Copy DKIM + CNAME values provided by ZeptoMail |
| 3 | Update DNS | Add the copied records to your domain's DNS provider (GoDaddy, Cloudflare, etc.) |
| 4 | Verify Domain | Click "Verify Domain" button in ZeptoMail |
| 5 | Wait for Propagation | Allow 24–48 hours for DNS propagation. Without verification, sending will be disabled. |
Configure Sender Email Addresses
Set up sender addresses for your verified domain. Example formats:
| Sr. | Sender Address | Use Case |
|---|---|---|
| 1 | noreply@yourdomain.com | Automated system notifications |
| 2 | support@yourdomain.com | Customer support responses |
| 3 | alerts@yourdomain.com | System alerts and warnings |
Describe Your Application
Zoho reviews accounts to prevent spam. Prepare this information for approval:
| Sr. | Information | Example |

| 1 | Application Screenshot | Screenshot of your application/website sending emails |
| 2 | Email Template | Sample of an email template your app will send |
| 3 | Trigger Events | Explanation of when emails are sent (e.g., "Email sent when user clicks 'Reset Password'") |
Email Content Compliance
Your transactional emails must include:
| Sr. | Requirement | Details |
|---|---|---|
| 1 | Clear Purpose | Email must have a clear transactional purpose (OTP, reset, confirmation, etc.) |
| 2 | Valid Sender | Use a legitimate sender address from your verified domain |
| 3 | Professional Domain | Sender address must be from a legitimate, owned domain (not free email) |

| 5 | No Purchased Lists | Never send to purchased, scraped, or unverified email lists |
Important Notes
Approval Timeline: Zoho typically approves accounts within 24–48 hours after all requirements are submitted.
Account Suspension Risk: Sending marketing emails, bulk campaigns, or emails from unverified lists will result in immediate account suspension with no refund.
Bounce & Complaint Monitoring: Keep bounce rates below 5% and complaint rates below 0.1%. High rates trigger automatic suspension.
Re-authentication: You may need to re-verify your domain if you change DNS providers or if DNS records are removed.
Free Tier Limits: Free accounts have sending limits (typically 1,000–3,000 emails/month). Upgrade to paid plans for higher volumes.
