ZeptoMail / Zoho CPaaS
Zoho's transactional email service, now documented as Zoho CPaaS. Use your account's current region, sending credentials, and transactional-only policy.
Start with the first guide, then choose a sending, receiving, or feedback task. Each walkthrough identifies permissions, operational checks, and the boundary between the service and MailKite. Refer to the official ZeptoMail / Zoho CPaaS documentation for current platform requirements.

Configure a ZeptoMail / Zoho CPaaS email Agent
Follow Zoho's current CPaaS documentation, verify the sending domain, and separate an email Agent's credentials from mailbox passwords.
Send transactional email through Zoho CPaaS SMTP
Use the email Agent's SMTP settings with TLS and the documented credential type rather than a personal Zoho mailbox login.
Operate and troubleshoot Zoho transactional email
Use the correct email Agent's logs and delivery controls to diagnose bounces, restrictions, and uncertain sends without mixing marketing traffic.
