The easiest way to set up Keeping is to login to your shared mailbox from Keeping and give Keeping access to your support mail. As an alternative, you can forward your support mailbox to Keeping.
If you aren't already viewing your mailbox, click on the pencil icon on your mailboxes page.
Click "Set Up Forwarding" to see your Keeping Forwarding Email address.
Copy your unique Keeping forwarding email address to your clipboard by clicking on the icon to the right of the address.
Login to the Gmail account that currently receives your support email.
Navigate to the Gmail settings for your support email account
Choose the Forwarding and POP/IMAP tab of your settings
Under Forwarding, click "Add a forwarding address."
Enter your unique Keeping email address that you copied in Step 3, and click "Next."
Gmail will send a confirmation email to your unique Keeping email address. Click OK and proceed to the next step.
Gmail confirms any new forwarding address with an email. Return to the Gmail account that you originally signed up for Keeping with, and check your inbox for a forwarding confirmation from Google.
Log back into your work Gmail account (or the address you used to create your Keeping account), and look for an email from Google asking you to confirm email forwarding.
Open the email, and click the link to confirm email forwarding to Keeping.
Almost there! After you have confirmed forwarding, you need to go back to the Gmail account for your support emails (eg support@ or help@), and return back to the settings for Forwarding and POP/IMAP and enable the forwarding.
Log back into the account that currently receives your support email (or, you may still be logged in). Return back to the settings.
As with before, return to the Forwarding & POP/IMAP tab. This time, choose the setting next to your Keeping email address. Don't forget to click Save Changes at the bottom of the page!
If you haven't done so already, you'll need to install the Chrome Extension.
Back in the Keeping settings, send a test email to confirm you have everything wired up correctly. You should receive a test email in your work account, inside the Keeping tab.
