Setting up your GoDaddy email account correctly using IMAP and SMTP with SSL/TLS ensures secure access, reliable email synchronization, and smooth sending/receiving across devices and email clients like Gmail, Outlook, Apple Mail, and Thunderbird.
This guide explains the exact incoming and outgoing mail server settings required to configure your GoDaddy email account successfully.
Incoming Mail Server Settings (IMAP)
IMAP (Internet Message Access Protocol) allows you to access your emails from multiple devices while keeping everything synchronized on the server.
Use the following Incoming Server (IMAP) settings:
- Server:
imap.secureserver.net - Port:
993 - Connection Security:
SSL/TLS - Username:
contact@guestpostai.com - Password: Your email account password
Why Use IMAP?
- Emails stay synced across all devices
- Messages remain stored on the server
- Ideal for professional and multi-device usage
Outgoing Mail Server Settings (SMTP)
SMTP (Simple Mail Transfer Protocol) is used to send emails securely from your email client.
Use the following Outgoing Server (SMTP) settings:
- Server:
smtpout.secureserver.net - Port:
465 - Connection Security:
SSL/TLS - Username:
contact@guestpostai.com - Password: Your email account password
Why SSL/TLS Matters
- Encrypts your email data
- Prevents unauthorized access
- Required by most modern email clients
Authentication Requirements
Ensure the following options are enabled in your email client:
- ✔ SMTP authentication enabled
- ✔ Username and password same as incoming server
- ✔ SSL/TLS selected (not STARTTLS)
Without authentication, most mail servers will reject outgoing emails.

Troubleshooting Tips
