Senders
A sender identity is the persona that owns channel accounts.
LinkedIn
Connect from Settings → Senders Accounts via Unipile hosted auth. Sending still goes through the connected seat.
Email
Connect one or more mailboxes:
- Google (OAuth)
- Microsoft 365 (Graph)
- IMAP/SMTP
Sends rotate across mailboxes on that sender (sticky per contact). Reply polling covers every attached mailbox.
Health
Unhealthy mailboxes or LinkedIn seats pause sending for that identity. Check this tab if a campaign is running but the pool is idle. Pair with Deliverability.
