# Sending limits and inbox warm-up

> How OpenATS paces sequence emails from each inbox to protect your sending reputation, and how to set your daily ceiling.

OpenATS paces sequence email from each recruiter’s Gmail: it starts at 20 a day in the first week, adds 20 a week up to the inbox’s ceiling, and spreads sends through the candidate’s working day. Set your own ceiling under **Settings → Integrations → Email inboxes → Sequence emails a day**.

## How pacing works

- **Warm-up:** an inbox sends up to 20 sequence emails a day in its first week, and 20 more each week after, until it reaches its ceiling.
- **Ceiling:** **Up to 25**, **50**, **100**, **150** or **200** a day, or the default marked **(recommended)**.
- **New people:** at most half a day’s emails go to people you’ve never written to.
- **Spread out:** at most 3 every 15 minutes, during the candidate’s working day.

Each sequence’s own **Daily send limit** applies as well. Warm-up counts from the inbox’s first sequence email.

## Set your ceiling

1. Open **Settings → Integrations → Email inboxes**.
2. Under your inbox, set **Sequence emails a day**.

Admins can set it for every inbox in the workspace under **Recruiter inboxes**.

> **Tip:** Raising the ceiling doesn’t skip warm-up: a new inbox still climbs 20 a week.
