Mailboxes let your sequences send email steps, and bring email replies into the same Inbox as LinkedIn. You can connect as many as your plan allows.
Only Owners and Managers can connect mailboxes.

Supported mailboxes

​
How to connect

  1. Go to Senders → Connect sender.
  2. Choose Gmail, Outlook or IMAP / SMTP, then click Continue.
  3. Fill in the details:
    • Client (optional)
    • Display name, for example jane@acme.com
    • Owner email
    • Timezone
  4. Click Open hosted login, or copy the link for the mailbox owner, and sign in. The link expires after 15 minutes.
The mailbox shows Connecting until sign-in is complete, then Connected.

​
Mailbox limits

Mailboxes start at warm-up level 3, which allows 80 emails a day. They can reach 120 a day at level 5. The platform maximum is 150 emails a day per mailbox. Like LinkedIn senders, mailboxes only send during their working hours.

​
Mailbox settings

Each mailbox has its own settings on its sender page: See Unsubscribe links, signatures and email tracking for all of these in detail.

​
Using a mailbox in a sequence

  1. Add the mailbox to the sequence’s Pool, or pick it directly in the Send email step’s Mailbox setting.
  2. Add a Send email step and connect its three outcomes: next, bounced and no email.
  3. Put {{unsubscribe_link}} in the body. The pre-launch check warns you if it’s missing.
A sequence with a Send email step can’t be activated until a mailbox is available. A pool of mailboxes splits the volume evenly, and a contact emailed before always gets the same one again. See Sequence Nodes for all the email step settings, including threading and open/click tracking.

​
Q: Does the Chrome extension work with mailboxes?

No, it isn’t needed. Mailboxes stay connected through OAuth or their credentials.

​
Q: What happens when someone unsubscribes?

One click on the {{unsubscribe_link}} — no login, no form — excludes them from all future outreach across the whole workspace, on every channel, and ends their live enrollments. Their lead shows an Unsubscribed badge, and the lead, timeline and conversation are all kept.
