Questions people ask first
My Gmail or Outlook.com is full. Do I have to buy more storage?
No. With the Personal plan, MailAttic moves your older mail out of the mailbox into encrypted storage you can still search and read, so the mailbox stays within its free storage. Download any year as a .pst whenever you like.
Does MailAttic delete mail from my mailbox?
No. Backing up only reads your mailbox. Mail leaves a mailbox only if you switch on inbox archiving for it, and only after MailAttic already holds its backup copy.
What happens when retention ends?
Only MailAttic's own copy is removed. Retention counts from when a message was received or backed up, whichever is later, so old mail you back up today is kept for the full period. Your mailbox is never changed by retention.
Which mail services work?
Microsoft 365 connects with one admin approval and finds every mailbox. Gmail, Google Workspace, Zoho, Yahoo, iCloud, Fastmail, GoDaddy, cPanel hosting and any other IMAP server connect with the mailbox address and its password, or an app password where the service requires one (Gmail, Yahoo, iCloud).
Where is my mail stored?
Encrypted in MailAttic. You can also keep copies in storage you own: OneDrive, Google Drive, Amazon S3, Wasabi, Backblaze B2, Cloudflare R2, Azure Blob or your own SFTP server or NAS. A guided setup tests each one before it is saved.
Can I bring my old .pst and .ost files?
Yes. Import them and MailAttic merges them with your backups into one archive per year, without duplicates and in the original folders. Download any year as a .pst again whenever you need it.
Who can see my mail?
Each organization's mail is encrypted with its own key. Users see the mailboxes their role allows, and every message opened in MailAttic is recorded in your organization's audit log.
How does the free trial work?
Every plan starts with a free trial and no card is needed to begin. Sign up with Google, Microsoft or your email, connect a mailbox, and your first backup starts in minutes.
