Shortwave imports your last 90 days of email history when you first sign up. To import your entire Gmail history and unlock unlimited search history, you'll need to upgrade your account.
Upgrade your account by creating a workspace and upgrading it to the Standard plan.
If you already have a workspace on the Standard plan:
Indicate whether the workspace is for your team or yourself
Select the Standard plan and enter your billing information securely in Stripe
Click "Start import" once you are redirected back to Shortwave
Shortwave will send you an email when your import is complete
The import process will run in the background, so you can close the app at any time. It may take several hours for us to import your full history, although we do import it in reverse chronological order.
