What ZeptoMail is
ZeptoMail, now Zoho CPaaS, is a paid email service built exclusively for transactional messages such as verification codes and password resets. Applications can send through SMTP relay or an email API, with separate credentials and tokens for mail grouped by domain, application, or purpose. Logs show status, recipients, bounces, clicks, and opens, while webhooks report those events to a public URL. Security options include encryption at rest, TLS, SPF, DKIM, CNAME verification, two-factor authentication, role permissions, and sending IP restrictions. Listed integrations include Zoho Flow, Zoho CRM, WordPress, Zapier, Microsoft Power Automate, Magento, Laravel, and Django. Technical assistance is included regardless of usage level. The first email credit is free and covers 10,000 emails for six months. Additional credits have no monthly minimum, but each recipient counts as one email and credits expire after six months. Promotional or bulk sending is directed to Zoho Campaigns.

Who it suits
ZeptoMail suits developers and organizations sending transactional email through SMTP or an API. It is intended for operational messages, not promotional or bulk campaigns.
Verdict
ZeptoMail focuses narrowly on transactional delivery while providing relay, API, event monitoring, security controls, and integrations. Credit expiry and the prohibition on promotional or bulk use are important planning constraints.
