Zoho SMTP Settings: A Complete Guide

What is SMTP?

SMTP stands for Simple Mail Transfer Protocol, and it’s the protocol used for sending emails over the internet. While IMAP or POP3 protocols are used for retrieving emails from a server, SMTP handles the sending part. When you send an email through an email client (such as Outlook, Thunderbird, or Apple Mail), it communicates with an SMTP server to deliver your message to the recipient’s inbox.

Zoho SMTP allows you to send emails via Zoho's server while using your Zoho Mail account for communication, which is essential for setting up custom email systems or third-party applications.

Zoho SMTP Settings

Before you configure Zoho SMTP in your email client or application, here are the key settings you need to know:

1. SMTP Server:
   • smtp.zoho.com
2. SMTP Port:
   • Port 465 for SSL (Secure Sockets Layer) encryption
   • Port 587 for TLS (Transport Layer Security) encryption
3. Authentication:
   • Required (You must authenticate using your Zoho email address and password)
4. Username:
   • Your full Zoho email address (e.g., yourname@zoho.com)
5. Password:
   • Your Zoho Mail account password
6. Encryption Method:
   • SSL for Port 465
   • TLS for Port 587
