Connect dedicated cold-outbound mailboxes, manage pool health, and stay within the per-user cap
Dedicated mailboxes that send your cold sequences.
A sending account is a real mailbox — a Google Workspace or Microsoft 365 inbox — that Laureo connects via OAuth and 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.
Admins connect mailboxes from the Mailboxes tab.
Connecting a sending mailbox is an admin-only action. From the Mailboxes tab, choose Connect mailbox and complete the OAuth flow:
Every mailbox shows a live status.
| Field | Description |
|---|---|
| Active | The mailbox is connected, authenticated, and sending within its current daily limit. |
| Paused — bounce rate | Auto-paused because the rolling bounce rate crossed the safety threshold. Replies still send. Review your list quality, then either resume (you confirm you understand the risk) or disconnect the mailbox. If the bounce rate stays high after you resume, Laureo pauses it again. |
| Paused — rate limited | The provider returned repeated rate-limit responses. Laureo backs off automatically and resumes when the provider allows it. |
| Paused — token expired | The OAuth connection needs to be re-authorized. Reconnect the mailbox to restore sending. |
| Paused — preflight regression | A previously passing domain check started failing (for example, a DNS record was removed). Re-run domain setup, then resume. |
Set how many cold emails a mailbox sends per day.
Every sending mailbox has an adjustable daily send limit. The recommended default is 30 emails per day, which keeps deliverability healthy for most senders. From a mailbox card, choose Edit next to Daily limit to raise or lower it, or leave it blank to return to the recommended default. Caps stay enforced at all times.
A mailbox can be connected to one organization at a time.
Each mailbox can hold exactly one active Cold Outreach connection. If you try to connect a mailbox that is already connected, Laureo asks you to disconnect the existing connection first. This prevents two configurations from sending from the same address and racing on its daily limit.
Stop using a mailbox for cold outbound.
An admin can disconnect a sending mailbox from the Mailboxes tab. Disconnecting stops new cold steps from sending through it; sequences that depend only on that mailbox pause until another mailbox is available. Replies already received remain in your inbox. Reconnect the mailbox at any time to resume — Laureo restarts its ramp from where the connection-age stage left off.
