04Questions
Questions, answered.
What does postkeep keep?
Your account details, your mailbox logins (app passwords and Microsoft sign-ins), stored encrypted, and a short log of new-mail alerts so they can be retried: 7 days, up to 1,000 per mailbox by default. Disconnect a mailbox and its login and alert log are deleted right away. The Privacy Policy has the full list.
How do I connect Gmail?
With a Google app password: a 16-digit code Google makes for apps like this one. It needs 2-Step Verification. Many work or school accounts, accounts under Advanced Protection or with security keys only, and accounts where an admin has turned app passwords off can't make one. You type it on a postkeep page, so it stays out of the chat. Signing in to postkeep with Google doesn't connect Gmail.
What happens at my plan's limit?
Your agent tells you how many mailboxes you're using and sends you a link to add more. Connections you've started but not finished count too. Your bill stays the same unless you upgrade.
Are there usage limits?
You pay for mailboxes, not for messages or for what your agent does. Fair use applies: very heavy use brings an alert first, then a slowdown. Your bill stays the same.
How do I cancel, and can I get a refund?
Cancel any time in Billing, without writing to us. Your plan stays active until the end of the period you've paid for. You can also cancel in Creem's customer portal; that ends the plan right away. Creem, our merchant of record, handles refunds; see the Refund policy. Read the Refund policy.
Who decides what my agent sends?
You do, in your agent app. Apps like Claude, ChatGPT, Cursor and VS Code can ask you before each email goes out; you choose this in the app's tool settings. postkeep sends what your agent asks it to, from your own address, and counts every send on your Usage page. What goes out is yours, like mail you send yourself.
Is postkeep open source?
The mail engine is open source under MIT, and Cloud runs that same engine, so you can move to self-hosting whenever you like. Accounts, billing and the other hosted parts are run by us. Engine fixes go back to the open-source project.
What if postkeep Cloud shuts down?
The mail engine is open source under MIT, and Cloud runs that same engine, so you can run it on your own machines whatever happens to Cloud.
