Zoho ZeptoMail

ZeptoMail is Zoho’s transactional email service for applications sending receipts, OTPs, or notifications. Developers integrate via SMTP or API, ensuring high deliverability rates. A simplified dashboard shows sending volume, bounces, and spam complaints. Email templates can be created and reused for consistent branding. ZeptoMail’s robust analytics let dev teams track open or click rates per campaign. While not a full email client, it suits businesses needing reliable infrastructure for system-generated emails separate from marketing blasts. By focusing on transactional reliability, ZeptoMail keeps critical app emails out of spam folders.
