# New-account sending limits
> How many emails a new organization can send per day, how the limit grows over 30 days, the hourly pacing, and what puts a send under review.
A new organization can send a limited number of emails a day. The limit rises automatically over
your first 30 days, then only your plan limits apply.
**Why:** mailbox providers distrust a sender with no history who suddenly sends a lot. Growing
volume gradually builds a reputation receivers trust, and it protects the shared servers other
customers send from.
## The daily limit
The limit is set per **organization**, by its age: the number of full days since the organization
was created. Your sign-up day is day 0.
| Organization age | Daily email limit |
| ---------------- | ---------------------- |
| Days 0–1 | 200 |
| Days 2–3 | 500 |
| Days 4–7 | 2,000 |
| Days 8–14 | 5,000 |
| Days 15–29 | 20,000 |
| Day 30 onwards | Your plan's limit only |

The limit applies to every sending domain in your organization together. Adding another domain
doesn't give you another allowance.
## Your plan limit still applies
Your plan sets a monthly email allowance. Brudcast spreads it into a daily limit of one-thirtieth of
the monthly figure, rounded up. On any day, you can send the **lower** of that figure and the
table above.
For example, on a plan with 30,000 emails a month the plan allows 1,000 a day:
* On day 1 your limit is 200 (the new-account limit is lower).
* On day 5 your limit is 1,000 (the plan limit is lower than 2,000).
The monthly allowance itself is never raised by the new-account limits.
## Pacing within the day
Your mail is also paced, so a whole day's allowance can't go out in a single burst.
| Window | Limit |
| ---------- | --------------------------------------------------------- |
| Per hour | The daily limit ÷ 4, rounded up |
| Per minute | The hourly limit ÷ 10, rounded up, and never less than 10 |
| Per second | 5 |
With a daily limit of 200, that's 50 an hour and 10 a minute.
What counts depends on the window:
* **Day and month** count **recipients**. An email to 3 people in To, Cc and Bcc counts as 3.
* **Second, minute and hour** count **requests**: one API call or one SMTP transaction, however
many recipients it has.
All windows reset on UTC time.
## Two more caps
| Situation | Daily limit |
| -------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------- |
| You only send from the [Brudcast trial address](/channels/email/overview), with no verified domain of your own | The lower of 500 and your limit from the rules above |
| One of your sending domains is **suspended** for its bounce or complaint rate | 200, whatever your age, until the domain recovers |
The second rule means reputation can move you back down the ladder. See
[Reputation and suspension](/deliverability/reputation-and-suspension).
## When you reach a limit
| How you send | What happens |
| ------------ | ------------------------------------------------------------------------------------------------------------- |
| Campaigns | Messages over the limit are held and retried for up to 24 hours, so the campaign finishes as the limit allows |
| Email API | `429` with `Rate limit exceeded: perDay` (or `perHour`, `perMinute`, `perSecond`, `perMonth`) |
| SMTP relay | `451 Rate limit exceeded:` followed by the window |
For the API and SMTP, retry after the window resets. See [Rate limits](/developers/rate-limits).
These limits apply to email. SMS has no new-account limit, though your SMS plan allowance is
spread across the month in the same way.
## Sending reviews
Separately from the limits, an unusual send can be held while someone at Brudcast looks at it. Most
reviews are approved and sending resumes, with nothing lost.
| Trigger | When it fires |
| ------------------------------------ | --------------------------------------------------------------------------------------------------------------------------- |
| **Large send on a free plan** | Your email plan is Free and a campaign is addressed to 500 or more recipients |
| **Sudden volume jump** | A campaign is addressed to 1,000 or more recipients **and** at least 10 times your average daily sends over the past 7 days |
| **Large import soon after sign-up** | You import 5,000 or more contacts within 24 hours of creating the organization |
| **Complaint spike** | 3 or more spam complaints in the past 7 days, while you sent 500 or fewer messages in that time |
| **Name resembles a protected brand** | Your organization's name looks like "Brudcast" or another reserved brand name |
The campaign checks run when you send a campaign. The complaint check runs once a day. Imported
contacts are always kept: a review only stops sending to them.
While a review is open, all sending from the organization is on hold, on every channel and through
the API and SMTP. A notification reads **Your sending is on hold pending review**, the campaign that
triggered it isn't sent, and sends are refused with `403 Sending is disabled for this account:`
followed by the reason on the API, or `550 Sending is disabled for this account:` on SMTP. Only one
review can be open at a time.
To speed a review up, email [support@brudcast.com](mailto:support@brudcast.com) with where the
contacts came from and what you're sending. Evidence of consent helps most.
