A sender is one person your sequences write as, with one name and signature across their connected mailboxes. Each contact is only ever emailed from the mailbox that emailed them first.
The Senders tab of the Senders and mailboxes page, with a New sender profile button above a table of senders, an Active chip beside one, each sender's mailbox count, and today's email and LinkedIn sends against each daily send limit.

The Senders tab.

​
Add a sender

1

Open the Senders tab

Open Senders & mailboxes and stay on the Senders tab.
2

Click Add a sender

Enter the sender’s name, then click Add sender. You land on the sender’s own Settings tab.
3

Fill in the Settings tab

Their first and last name feed the sender variables in your emails, and the Signature box is the plain-text signature every email from this sender ends with. Both are the sender’s, not any one mailbox’s, so every mailbox they send from signs the same way. Click Save.
A sequence sends as a sender, never as a mailbox. A sender with no mailbox sends nothing, so the launch checks block launch until it has one.

​
Add mailboxes to a sender

Click the sender’s row on the Senders tab, then open its Mailboxes tab. Click Add from this workspace, tick the ones this sender sends from, then click Save. Connect mailbox adds an account nobody in the workspace has connected yet.

​
Decide what sends without you

Send mode, on the sender’s Settings tab, settles it for this sender alone:
  • Send when confident sends what the agent is confident in and holds the rest in Tasks. New senders start here. A sequence’s AI writing tab shows which messages would wait.
  • Always ask holds every message and every reply from this sender for a person.
  • Always send sends everything the agent writes, including replies. Only a workspace admin can choose it, after confirming a warning.
Job title and Booking link live on the same tab. The agent uses them when a message says who you are or offers a time. It never writes your name into the body: the signature does.

​
Set the sender’s timezone

Timezone, on the same tab, sets the sender’s clock. Their daily limits reset at its midnight, and sequences send in its hours unless they fix one zone. Oneprofile detects it once, and after that only a person changes it.

​
See what went out as the sender

Click the sender’s row on the Senders tab, then open its Activity tab. Click a row to read what went out and how it went.

​
Act on several senders at once

Tick senders on the Senders tab and a bar appears above the table. Set signature writes one signature to every ticked sender; use sender variables so it signs as each person. Delete removes them, leaving their mailboxes connected.

​
Good to know

The workspace has no sender yet, so the Senders tab offers Email sender and LinkedIn sender instead. Each asks for the sender’s name, then click Add sender.Email sender opens the new sender’s Mailboxes tab. When the workspace has no mailbox yet, Google’s sign-in starts first and comes back to that tab. LinkedIn sender opens their LinkedIn tab to connect. Fill in their Settings tab afterwards.
Its Mailboxes tab offers Connect Gmail and Import from InboxKit in place of Connect mailbox. Connect Gmail opens Google’s sign-in for this sender straight away. Add from this workspace shows only while the workspace has mailboxes to add.
A message that trips a check:
  • a placeholder that did not fill
  • a claim the agent could not ground
  • too little known about the contact to write anything worth sending
Yes. A sequence, or a single step inside it, can ask for approval on top of the sender’s mode, and neither can take one away. A sequence sending from several senders takes the strictest mode among them.LinkedIn text is governed the same way, while the browser side of LinkedIn is set separately on the sender’s LinkedIn tab and starts on Manual run.
It can lower one, never loosen it. A sender whose replies start to look wrong is put on Always ask: too many in an hour, too many in one thread, or several ending badly.You are notified when it happens, and an admin can set the sender back.
From the browser of whoever added the sender. A sender added without one takes the timezone of the browser that connects its LinkedIn. Clearing the field lets Oneprofile detect it again.Adding a sender for a teammate who works in another timezone? Set their Timezone yourself, since the sender starts in yours.You can also ask the AI Assistant, such as “set Maya’s timezone to Europe/Berlin”.
At midnight in the sender’s timezone, for email and LinkedIn alike. A weekly LinkedIn limit counts the sender’s last seven days. A sender with no timezone yet resets at midnight UTC.When the timezone changes, the day already under way finishes first, so a change never starts a fresh day early. Workspace analytics and sequence charts still count days in UTC.
Every mailbox takes its turn. A new contact goes out from the mailbox whose next send is soonest, then the one that has sent least today. Emails from one mailbox keep their spacing, and every send stays inside the sequence’s sending window. A contact who would fall after the window shuts waits for the next opening.
No. Once a sender has a timezone, Oneprofile never changes it on its own, even when the browser that runs their LinkedIn is in another zone. Change it under Timezone on the sender’s Settings tab.
  • Emails a sequence sent as the sender, and replies sent from the Inbox since October 5, 2026. Forwards, test emails and emails that failed to send are not listed.
  • LinkedIn steps that reach someone, such as a profile view, a connection request or a message, including ones that failed.
  • Tasks someone rejected in Tasks. Discarding a draft in the Inbox is not a rejection.
Filter by Channel, Decision, Outcome or When, or search by contact or subject. Sort by the When or Contact column.
What went out, as it went: the email, the message, or the profile a step acted on. Under it come who let it go, how it ended and, for a failed step, why. Open sequence, Open conversation and Open task go to where it came from.
The Decision filter offers these words, and a row adds who, such as “Approved by Maya Chen”:
  • Approved: a person or an API key approved it first. Opening the row says why it waited, such as “Held because this sender always asks”.
  • Automatic: no person decided. The sender’s and the sequence’s rules let it go.
  • Rejected: a person refused it in Tasks, so it never went.
  • Sent by a person: someone wrote it and sent it from the Inbox.
  • Not recorded: a LinkedIn step from before Activity, whose approval a later step replaced.
  • Sent: the mail provider accepted the email.
  • Done: the LinkedIn step did its job.
  • Failed: it did not go through. Open the row to read why.
  • Skipped: the step no longer applied, such as a request to someone already connected.
  • Already pending: a connection request to this person was already pending when the step ran. It waits for the answer like one Oneprofile sent.
  • Stopped: it was stopped while a browser was running it.
  • Not sent: a person rejected it in Tasks.
Steps that reach someone are on the Activity tab, beside the sender’s emails, with who approved each. The LinkedIn tab keeps the queue, the browsers and the limits, and its queue line names the step running now. The extension’s side panel lists every step it ran, checks included.
They reach nobody. Checks of the sender’s own LinkedIn inbox, sent requests and new connections, and reads of a conversation, only look at their account, so Activity leaves them out. The extension’s side panel lists them.
Yes, such as “what did Maya send this week, and who approved it?”. It reads the same list, with the same filters, and links to the Activity tab.
Deleting it stops every live contact it emailed at their next email. Moving it to another sender stops them only in sequences that sender is not on. Either way they read Mailbox removed, and no other mailbox takes over. LinkedIn steps before their next email still run.Unticking a mailbox leaves it connected, and the contacts it emailed wait for it to go back on a sender.Before you delete, untick or move a mailbox, the dashboard counts the live contacts it stops or leaves waiting in each sequence. Stopped contacts resume from the Audience tab once the address is back on their sequence.
