Gmail POP and SMTP settings are the server details that allow you to receive Gmail emails using POP (Post Office Protocol) and send emails using SMTP (Simple Mail Transfer Protocol) from third-party email clients like Outlook, Thunderbird, Apple Mail, or mobile apps. Gmail’s POP server downloads incoming emails to your device, while Gmail’s SMTP server securely sends outgoing emails using your Gmail account.
Once these settings are configured correctly, you can use Gmail without opening the Gmail website—perfect for professionals, businesses, and anyone managing multiple email accounts from one place.
Understanding Gmail POP and SMTP Settings
Before diving into the exact settings, it’s important to understand what POP and SMTP actually do and why they matter.
What Is POP in Gmail?
POP (Post Office Protocol) is used to receive emails from Gmail’s servers. When POP is enabled, your email client connects to Gmail and downloads messages to your device.
Key characteristics of Gmail POP:
- Emails are downloaded from the Gmail server
- Messages can be deleted from the server or kept (your choice)
- Best for single-device access
- Works offline once emails are downloaded
What Is SMTP in Gmail?
SMTP (Simple Mail Transfer Protocol) is responsible for sending emails. Every time you click “Send” in an email app, SMTP handles the delivery.
- Authenticates your Gmail account
- Encrypts outgoing messages
- Ensures reliable email delivery
- Prevents spam and abuse
Official Gmail POP Settings (Incoming Mail)
Use the following Gmail POP server settings to receive emails in any email client.
Gmail POP Server Details
- POP Server: pop.gmail.com
- Port: 995
- Encryption: SSL/TLS
- Username: Your full Gmail address ([email protected])
- Password: Your Gmail password or App Password
- Authentication: Required
Important POP Configuration Options
When setting up POP in Gmail:
- Enable “Leave a copy of retrieved messages on the server” if you want access from multiple devices
- Select “Archived Emails copy” to place your inbox clean
- Avoid deleting emails from the server unless you’re sure
Official Gmail SMTP Settings (Outgoing Mail)
To send emails using Gmail from any third-party app, configure the following SMTP settings.
Gmail SMTP Server Details
- SMTP Server: smtp.gmail.com
- Port (SSL): 465
- Port (TLS): 587
- Encryption: SSL or TLS
- Username: Your full Gmail address
- Password: Your Gmail password or App Password
- Authentication: Required
Which SMTP Port Should You Use?
- Port 587 (TLS): Recommended and most compatible
- Port 465 (SSL): Older but still supported
- Avoid Port 25 (often blocked by ISPs)
How to Enable POP in Gmail (Step-by-Step)
By default, POP may be disabled in Gmail. Follow these steps to enable it:
- Log in to your Gmail account
- Click the gear icon → See all settings
- Go to Forwarding and POP/IMAP
- Under POP Download, select:
- “Enable POP for all mail” or
- “Enable POP for emails received from this point forward.”
- Choose what happens to Gmail’s copy of messages
- Click Save Changes
POP is now active and ready for configuration in your email client.
Gmail App Passwords (Very Important)
If your Gmail account uses 2-Step Verification, you cannot use your normal password in email apps.
Instead, you must generate an App Password.
How to Create a Gmail App Password
- Go to your Google Account
- Open Security
- Enable 2-Step Verification
- Click App passwords
- Select:
- App: Mail
- Device: Windows / Mac / Other
- Copy the generated password
- Use this password in POP and SMTP settings
This improves security and prevents unauthorized access.
POP vs IMAP for Gmail: Which Is Better?
While this article focuses on POP, many users wonder if IMAP is better.
POP Is Best If:
- You use only one device
- You want emails stored locally
- You need offline access
- You prefer simple setups
IMAP Is Better If:
- You use multiple devices
- You want real-time syncing
- You manage folders across devices

For modern workflows, IMAP is usually recommended, but POP still works perfectly for backups and single-device setups.
