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.
Infomaniak uses your regular password. If two-factor authentication is enabled on the account, a dedicated app password must be created from the Infomaniak Manager.
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, all that's missing is your address and your app password.
- Enter the credentials for your Infomaniak mailbox — same on the destination side (mail.infomaniak.com, port 993).
- Start the transfer — MailSync connects to both mailboxes and copies the messages folder by folder.
- Follow the progress in real time — you can close the page, the operation keeps running in the background.
- Check the result — find all your messages and folders in your Infomaniak mailbox.
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.
- Server-side filtering rules, signatures or auto-replies are not copied: only the messages and their folder organization are.
- Beyond 5GB, finishing the operation requires a one-off payment or the Premium plan.
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.
Do I need an app password for Infomaniak? +
No, not in the general case. Infomaniak uses your regular password. If two-factor authentication is enabled on the account, a dedicated app password must be created from the Infomaniak Manager.
Are messages deleted from my Gmail mailbox? +
No, never automatically. MailSync copies your messages from Gmail to Infomaniak, it doesn't move them: your Gmail mailbox stays intact after the operation. You can empty it yourself once you've checked the copy, if you want to.
How long does a transfer from Gmail to Infomaniak take? +
It mostly depends on the volume of your Gmail mailbox and the write speed accepted by the Infomaniak server. Usually a few minutes for a few hundred messages, longer for a large volume. You can follow progress in real time and close the page.
Is there a volume limit for this transfer? +
The transfer from Gmail to Infomaniak is free up to 5GB. Beyond that, the first 5GB are transferred for free; then finish the operation for 4,99€ excl. VAT (5,99€ incl. VAT) or switch to Premium.
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.
