To connect another inbox, open the account menu at the bottom of the sidebar and click Add another account, then sign in with Google or Microsoft. The new inbox joins your existing subscription at no extra charge. Inviting a teammate is a different thing: it adds a paid seat. Most surprise "why was I charged for two seats" bills come from mixing these up.
A connected inbox and a team seat are not the same
| Add another account | Invite a teammate | |
|---|---|---|
| Where | Account menu → Add another account | Settings → Team → Invite members |
| What it's for | More of your own inboxes under one login | A second person with their own login |
| Price | Included in your plan | One more paid seat on your subscription |
| Credits | Shares your credit allowance | Adds that seat's credits to the team pool |
| Limit | Plus: 2 inboxes per user. Pro: 8 per user | One seat per person |
Before an invite goes out, Jace asks you to confirm with Invite & add seat and tells you that a paid seat is being added. If you only wanted to read a second mailbox yourself, cancel that dialog and use Add another account instead. The team setup guide covers how seats and invites are billed.
Inbox limits on Plus and Pro
Plus connects up to 2 inboxes per user and Pro up to 8, with unlimited calendars on both (pricing). When you reach the limit on Plus, the account menu shows Upgrade to Pro for up to 8 accounts in place of the add button. On Pro, it shows Need more? Talk to Sales!
Every inbox you add shares your credit allowance. Each connected inbox has its own labels and settings, so auto-drafts run separately in each one. If credits start running out after you connect a busy inbox, see Why your credits run out.
Switch between inboxes
Open the account menu in the sidebar and pick the inbox you want. Settings you change, such as labels or Autodraft only when directly addressed, apply to the inbox you're in.
Shared mailboxes and aliases
Jace connects mailboxes that have their own sign-in. Delegated or shared mailboxes that you open through someone else's Outlook account, and send-as aliases, don't connect as separate inboxes. If a shared address has its own password, add it with Add another account like any other inbox.
Remove an inbox
Switch into the inbox you want to remove, then go to Settings → Account and click Disconnect followed by its address. This removes that inbox and its contents from Jace and leaves your other inboxes and your subscription as they are. Full steps are in Disconnect or delete an account.
