How to Set Up Zoho Mail as Your SMTP Provider in Sparkforge

Zoho Mail is a solid SMTP provider for Sparkforge — particularly if your business email already runs on Zoho. Setup takes the same form as any SMTP integration: server, port, credentials.

Outgoing server: personal Zoho accounts

For personal users with addresses like username@zoho.com:

• Server: smtp.zoho.com
• Port: 465 (SSL) or 587 (TLS)
• Authentication: required

Note: free email addresses sometimes can't be used as SMTP senders due to deliverability rules. If yours is rejected, use a domain-based Zoho address instead.

Outgoing server: domain-based Zoho accounts

For organization users with addresses like you@yourdomain.com:

• Server: smtppro.zoho.com
• Port: 465 (SSL) or 587 (TLS)
• Authentication: required

Credentials

• Username: your Zoho username, or your full Zoho Mail address. For domain accounts on Zoho, that's you@yourdomain.com.
• Email Address: your Zoho Mail address (same as above for domain users).
• Password: your Zoho account password — or an app-specific password if 2FA is enabled on the Zoho account.

If 2FA is on, generate an app password

Zoho blocks raw account passwords from SMTP when 2FA is active. Generate an application-specific password in your Zoho admin console and paste that into Sparkforge's password field instead. Account-level 2FA stays on — only SMTP uses the dedicated app password.

Connect in Sparkforge

1. Open Settings > Email Services in your sub-account.
2. Click Add Service and pick a custom SMTP provider.
3. Enter the Zoho server, port, username, and password (or app password).
4. Save and send a test email to confirm.
