Frequently Asked Questions
How often does Gmail synchronize with my email client?
The synchronization frequency depends on your client settings. Most clients check for new emails every 5-15 minutes by default, but this can usually be adjusted. IMAP clients typically synchronize changes immediately when they occur.
Can I synchronize only specific labels or folders?
Yes, most email clients allow you to select which IMAP folders (which correspond to Gmail labels) to subscribe to. This lets you synchronize only the labels you need on each computer, saving bandwidth and storage space.
Why are some emails missing on one of my computers?
This usually occurs due to one of three reasons:
- The email client on that computer isn’t subscribed to the folder/label containing those emails
- The client has a filter that’s hiding or moving those emails
- The client is configured to only show recent emails (check your download settings)
How can I reduce the amount of bandwidth used for synchronization?
To minimize bandwidth usage:
- Reduce the number of emails stored offline in each client
- Unsubscribe from unnecessary labels/folders
- Increase the synchronization interval
- Avoid synchronizing large attachments
- Use Gmail’s “Basic HTML” view when on slow connections
