Sending Accounts

Connect dedicated cold-outbound mailboxes, set the name and the daily limit recipients feel, and read pool health

What sending accounts are

Dedicated mailboxes that send your cold sequences.

A sending account is a real mailbox, on Google Workspace or Microsoft 365, that Laureo connects and then uses to send cold-sequence steps and receive the replies. Cold sequences send only from these dedicated mailboxes, never from your primary CRM inbox, so your day-to-day email reputation stays separate from your cold-outbound reputation. They live on the Mailboxes tab, one card each.

How many mailboxes you can connect
The pool meter at the top of the tab counts your own mailboxes, not the whole organization's, and the limit is per person: on Ultra it is 5 sending mailboxes per user, so two teammates can connect five each. Your plan sets this number, and it can be raised for one organization, so the meter at the top of the tab is always the one that applies to you. At the limit the connect control goes quiet and names the number you are allowed. More mailboxes spread your daily volume across more reputations and let Laureo rotate sends, but every send still stays inside the per-mailbox limits described in Deliverability.

A larger pool syncs the same way a small one does. Every mailbox keeps its own connection, its own daily cap and its own reply sync.

Connecting a mailbox

Connect mailbox, then the provider sign-in, then back here.

Connect mailbox opens a short explainer before it sends you anywhere. It leads with the one thing people get wrong: cold outreach sends from a dedicated sending account, not your everyday inbox. Under that sit three named parts.

FieldDescription
What you’ll needThe two things that decide whether the sign-in can succeed: a work email account on a business domain (free personal accounts cannot send cold outreach), and a mailbox that is not already connected to Laureo as an everyday inbox.
Choose your providerTwo buttons, Google Workspace and Microsoft 365. Either one takes you to your provider to sign in and grant access, then brings you back to the Mailboxes tab. The line underneath says exactly that.
Good to knowThe three things worth knowing before you decide: access is mail-only, to send and read replies, with no calendar, no contacts, and no files; sending starts on a managed ramp with daily caps so volume grows gradually; and best results come from a separate domain with 2 to 3 mailboxes on it.

That is the first-connect version. Once you have one mailbox the control reads Add mailbox, the explainer is titled Add a sending mailbox, and everything except the lede and the provider choice folds behind a closed What you'll need toggle. Open it if you want the detail again; otherwise a repeat connect is two clicks.

Free personal accounts are rejected
Cold Outreach needs a mailbox on a business domain you control, so SPF, DKIM, and DMARC can be configured and the domain can be authenticated. A free personal account is refused during the connect, not afterwards.
A mailbox connects to Laureo once
Each mailbox holds one connection. If you try to connect a mailbox that is already connected, either as your everyday inbox or as somebody's sending mailbox, Laureo says That mailbox is already connected, either as a personal inbox or as a sending mailbox. Disconnect it from the other place first. This keeps two configurations from sending from the same address and racing on its daily limit.

Who can connect one

Any role, on an owner or power seat.

Connecting a sending mailbox is not tied to being an admin. Any role can do it, provided the person holds an owner or power seat. Collaborator and viewer seats are fenced out, and a connect attempt from one comes back to the Mailboxes tab with a message rather than completing. If your organization is on a plan without Cold Outreach, or sending has been suspended on the account, the connect is refused the same way.

Microsoft 365 adds one step for some tenants: a tenant administrator has to approve Laureo once, for the whole tenant. When that is what is missing, the page says so and gives you the approval link to pass on. After your admin approves, connect again and it goes through.

Mailbox health states

Every card carries one status, top right.

The status is a coloured dot and one word. There are four, and they are derived from the mailbox itself, so nothing has to be refreshed by hand.

FieldDescription
SendingConnected, authenticated, its provider connection is live, and it is sending inside its current daily cap. The normal state.
PausedSending is held. Either you pressed Pause sending, or Laureo paused it automatically because its rolling bounce rate crossed the safety threshold. Replies still send while a mailbox is paused; only new cold steps hold.
Setup requiredThe mailbox is connected but not ready, and there are two independent causes. Either its domain authentication has not passed, or the provider connection that delivers replies has lapsed. Re-check now clears the first one only: it re-runs the DNS lookup and nothing else. A lapsed connection is cleared by Reconnect, which sends you back through the provider sign-in. The card names which one it is.
DisconnectedNo longer sending. It stays on the grid so you can reconnect it or take it off the pool for good.

When a provider gives a reason a mailbox stopped, the card states it above the numbers, together with the fix. Two other notices can appear there: a warning when the mailbox is on your primary company domain (cold sending from it can hurt deliverability for your whole company, and a separate sending domain is safer), and the managed-ramp badge described below.

Resuming a bounce pause asks you to confirm
A mailbox paused for bounces does not resume on one click. The confirmation says This mailbox was paused automatically because its bounce rate crossed the safety threshold. Resuming sends to your remaining leads at the managed daily cap. Review your list quality first: if the bounce rate stays high, Laureo pauses this mailbox again. The safety net stays armed after you resume, which is the point.

The name recipients see

From name, and what it falls back to.

Each card shows a From name row: the sender name that appears next to your subject line in the recipient's inbox. Edit opens Mailbox settings, where From name is the first field. It holds up to 120 characters and its note reads Shown to recipients as the sender name. Defaults to your profile name.

  • Leave it blank and your profile name is used. The card then says Taken from your profile name. Recipients see it next to the subject line. Change your profile name and the sender name follows it.
  • Type a name and that name is used instead, for this mailbox only. The card drops to Recipients see this next to the subject line.
  • With neither, recipients see the bare address. The row reads Not set and the note names the consequence in full: Recipients see you@yourdomain.com with no name next to the subject line.

The daily limit

How many cold emails one mailbox sends per day.

The Daily limit row sits under the From name, and its Edit opens the same Mailbox settings dialog. An unset limit reads 30 per day (recommended). Clear the field to go back to that recommendation at any time.

  1. Above 50 per day from one mailbox, Laureo warns you. It is a recommendation, not a block. Sending that much from a single mailbox raises the chance of landing in spam, and spreading the volume across more mailboxes is safer.
  2. Your provider enforces its own hard ceiling, around 2,000 per day. You cannot set a limit above it.
  3. A new mailbox is still ramping, so a raised limit does not take effect immediately. The real cap today is whichever is smaller.
The card tells you which number is actually in force
Whenever the ramp is below your configured limit, a second line appears directly under the row: Sending 10 per day while this mailbox ramps. Your limit of 50 applies from September 7, 2026. The save confirmation says the same thing, so you never leave the dialog believing a number that is not the one in force yet.

The managed ramp on each card

Ramp · week 2 of 3 · 20 per day.

Every mailbox carries a ramp badge. A new one starts at a low daily volume and steps up each week through 3 stages, 10 then 20 then 30 per day, so the sending domain's reputation is built gradually rather than announced. The badge reads Ramp · week 2 of 3 · 20 per day while that is happening, and its info affordance carries the reason plus the date your own limit takes over. Once the ramp finishes the badge settles to Full pace · 30 per day and stays there.

The ramp is driven by how long the mailbox has been connected, and nothing else. You cannot configure it or push a mailbox past its current stage. Today's sends just above the ramp badge is the live count against the cap actually in force, and Bounce trend (14d) below it is the signal to watch before raising anything.

Pausing and disconnecting

Pause sending on the card, Disconnect in the row menu.

Pause sending holds new cold steps from that mailbox and leaves everything else alone. Disconnect mailbox lives in the row menu and asks first: Sequences using this mailbox will redistribute new sends to your other mailboxes. Threads it already started keep their history but can no longer be replied to from Laureo. A mailbox that is already disconnected offers Remove from pool instead, which takes the card off the grid.

Sequences that depend only on a mailbox you disconnected hold their sends until another mailbox is available, and the lead rows say so. Reconnect at any time to resume: the ramp picks up from where the connection age puts it, not from week one.
