Unified inbox

You can view and manage emails across multiple accounts from a single inbox in Shortwave. You can do this by setting up a configuration in Gmail that links your secondary accounts to a single primary account, and then using that primary account in Shortwave.

How linking works for a unified inbox

To unify your inboxes in Shortwave, first you’ll need to choose a primary account. This is the account you will use to log into Shortwave. Then you will link your other accounts to your primary account. Linking your accounts allows you to view all of your emails in a single inbox, sync email history, and send messages from your other account addresses using aliases.

This works to unify both Gmail and non-Gmail accounts alike.

Connect your secondary accounts

Enable POP in your secondary account’s settings
- For Gmail & Google Workspace accounts, you can enable this via Gmail’s Forwarding and POP/IMAP settings → Enable POP for all mail
On your computer, sign in to Gmail with your primary account
Open your Gmail settings for Accounts
Under the “Check email from other accounts” section, click Add a Mail account
Enter your email address → Next
Select your connection process → Next
- Link with Gmailify – select this option if available to you
- Import POP3 – for other POP addresses, this will be the only available option
Follow the on-screen instructions to complete the process

If you see an error for incorrect information during this step, you may need to create a one-time App Password and use that instead of your regular email password
Optionally, you can update your Gmail alias settings if you’d like to change your default alias for sending emails
Sign in to Shortwave using your primary account
Click the Refresh Gmail data button to sync your Gmail settings changes to Shortwave for your unified inbox

Connection settings

Below are the standard settings for linking Gmail and Outlook-based accounts in Step 7

Gmail & Google Workspace

Username: your full email (example@domain.com)
Password: your Gmail password for that email address (or an App Password)
POP Server: pop.your_domain.com (ex. pop.gmail.com, pop.acme.com)
Port: 995
✅ Always use a secure connection

Outlook accounts

Username: your full email (example@outlook.com)
Password: your Outlook password
POP Server: outlook.office365.com
Port: 995
✅ Always use a secure connection

For other POP3 accounts, ask your Administrator for these settings. Note: Exchange accounts are not supported at this time.

💡 Other ways to unify accounts

In lieu of Gmail's linking option, you can enable auto-forwarding and add your address as an email alias to a Gmail account. This allows you to receive all of your emails in a single inbox, and reply from the same address the message was sent to. You can even export your historical emails and import them to Gmail for access to past messages and information.

Sync and troubleshooting

Shortwave automatically keeps things in sync with Gmail. For linked accounts from other providers (i.e. Outlook), you can see how Gmail syncs with non-Gmail accounts here.

If you encounter issues when linking your accounts:

Ensure you have POP access enabled in your secondary accounts
Try using an App Password instead of your regular Gmail password for Step 7
Refer to this troubleshooting guide
For Google Workspace accounts, confirm the setting “Allow per user outbound gateways” is enabled via Google Admin Console > End User Access settings
If Gmail does not automatically import your historical emails, follow these steps to import your old emails manually
