# Email sending limits and the warm-up ramp

How many emails each mailbox and campaign can send, how the warm-up ramp works, and why Victoria has no separate warm-up service.

Victoria AI limits how fast each mailbox sends, so a new mailbox builds a sending history before it sends at volume. Three limits apply, and the lowest one wins on any day.

## Email limits per campaign and per mailbox

| Limit | Default |
| - | - |
| Emails per campaign, per day | 30 |
| Emails per mailbox, per week | 500 |
| Emails per mailbox, per day, while ramping | See the ramp below |

The per-campaign daily limit is a campaign setting; change it in **Campaigns → your campaign → Settings → Daily Limits**. See [Work hours and daily limits](https://docs.versionseven.ai/help/work-hours-and-daily-limits). The weekly limit per mailbox is fixed. Days are counted in US Eastern time.

## Email warm-up ramp for a new mailbox

For its first 14 days a new mailbox has a daily cap across all its campaigns:

| Ramp day, as the app shows it | Emails per day |
| - | - |
| Days 1 to 3 | 5 |
| Days 4 to 7 | 10 |
| Days 8 to 14 | 20 |
| After day 14 | The campaign's daily limit |

Day 1 is the day the mailbox connected. While it ramps, the row on **Sender Accounts** shows the day and today's cap, for example **Day 2 of 14 · 5/day**. Reconnecting a mailbox doesn't restart its ramp.

## Skip the email ramp

Owners and admins can select the chip on the mailbox's row, then **Skip ramp** under **Sending limits**. The mailbox moves straight to the campaign's daily limit. New and recently reconnected mailboxes that send at full volume immediately are far more likely to be rate-limited by the mailbox provider. The skip is recorded with your name and can't be undone.

## Why Victoria AI has no mailbox warm-up service

Victoria AI doesn't run a warm-up network that sends and replies between mailboxes. The protection is the ramp and the caps above, plus checks on your domain:

- SPF, DKIM and DMARC are checked when a mailbox connects and every day after. A failing domain blocks campaign activation. See [DNS setup](https://docs.versionseven.ai/help/dns-setup).
- Every message is written for one person rather than sent as a blast.

For a new mailbox, use a third-party warm-up service as well, on a dedicated sending domain rather than your everyday mailbox. See [Sending mailbox best practices](https://docs.versionseven.ai/help/sending-mailbox-best-practices).

## Campaign sends fewer emails than the limit

A campaign can send less than its daily limit when:

- The mailbox is still ramping. Check the day count on **Sender Accounts**.
- The mailbox reached its weekly limit.
- The campaign is outside its work hours.
- Few leads are due an email step today.
