IMAP server and port already filled in for Gmail — all that's left is to enter your credentials.
IMAP settings for Gmail
Gmail
- IMAP server
- imap.gmail.com
- Port
- 993
- Encryption
- SSL/TLS
- App password
- Required
Gmail requires an app password: your regular password is rejected over IMAP once 2-step verification is on. Without 2-step verification, Google blocks "less secure app" IMAP connections anyway, so an app password remains the most reliable option.
App password for Gmail: Turn on 2-Step Verification, then generate an app password from your Google account's security settings.
How it works
- Enter the credentials for your Gmail mailbox — the server (imap.gmail.com, port 993) is already filled in.
- Start the analysis — MailSync connects to your Gmail mailbox read-only.
- Review the resulting statistics — size per folder, most frequent senders, breakdown by year.
What this tool doesn't do
- The operation only works over IMAP: a mailbox reachable only via POP3, or through a closed proprietary connector, can't be used.
- MailSync doesn't read the content of your Gmail messages: it's limited to headers (sender, date, size).
Frequently asked questions
Do I need an app password for Gmail? +
Yes. Turn on 2-Step Verification, then generate an app password from your Google account's security settings. Gmail requires an app password: your regular password is rejected over IMAP once 2-step verification is on. Without 2-step verification, Google blocks "less secure app" IMAP connections anyway, so an app password remains the most reliable option.
Is my Gmail account changed during the analysis? +
No. The connection to Gmail is read-only: no message is deleted, moved, or marked as read. MailSync only looks at technical headers (sender, date, size) to build statistics, without ever opening the body of an email.
Is there a volume limit to analyze my Gmail mailbox? +
No, the analysis is entirely free regardless of the volume of your Gmail mailbox, with no account required.
Are my Gmail credentials stored? +
No. Your IMAP credentials are encrypted with libsodium for the duration of the operation, then erased as soon as it finishes. If you're signed in to your MailSync account and choose to save the mailbox, only that one is kept (encrypted); you can delete it at any time.
