# Understanding Email Sending Limits

# Understanding Email Sending Limits

Email sending limits protect your sender reputation and ensure deliverability. Learn how limits work and how to adjust them.

## Why Limits Exist

Sending too many emails too quickly can:
* Trigger spam filters
* Damage sender reputation
* Get your domain blacklisted
* Reduce deliverability

## Default Limits

Each connected email account has a daily sending limit. The default depends on your email provider and account age.

## Viewing Your Limits

1. Go to [Settings / Integrations](https://app.100hires.com/settings/integrations)
2. Find your connected email account
3. See current daily limit and usage ![Understanding Email Sending Limits: Viewing Your Limits](https://storage.crisp.chat/users/helpdesk/website/-/4/f/a/a/4faab8f2b2ab0400/understanding-email-sending-li_1ptbe35.png)

## Adjusting Limits

1. Go to [Settings / Integrations](https://app.100hires.com/settings/integrations)
2. Click the **pencil icon** next to your email account
3. Adjust the daily sending limit ![Understanding Email Sending Limits: Adjusting Limits](https://storage.crisp.chat/users/helpdesk/website/-/4/f/a/a/4faab8f2b2ab0400/understanding-email-sending-li_9rcrds.png)
4. Save

**Warning:** Setting limits too high with poor reputation will cause emails to land in spam.

## Monitoring Email Queue

When you have more scheduled emails than your daily limit allows:

1. Emails queue and send over multiple days
2. View scheduled emails in email stats
3. Example: 500 emails with 50/day limit = 10 days to complete

## Calculating Send Time

| Emails | Daily Limit | Days to Complete |
| ---- | ---- | ---- |
| 100 | 50 | 2 days |
| 500 | 50 | 10 days |
| 500 | 100 | 5 days |
| 1000 | 200 | 5 days |

## Using Multiple Accounts (Email Carousel)

Split volume across multiple email accounts:

1. Connect multiple email addresses
2. Set up Email Carousel at [Settings / Email Carousel](https://app.100hires.com/settings/email-carousel) ![Understanding Email Sending Limits: Using Multiple Accounts (Email Carousel)](https://storage.crisp.chat/users/helpdesk/website/-/4/f/a/a/4faab8f2b2ab0400/understanding-email-sending-li_6m2025.png)
3. Campaigns split automatically across accounts
4. Example: 5 accounts × 50/day = 250 emails/day total

## Email Warm-up

New email accounts need warm-up before high-volume sending:

1. Enable warm-up in Email Carousel settings
2. System gradually increases sending volume
3. Daily limit auto-adjusts based on warm-up progress
4. Takes 2-4 weeks for full warm-up

## Canceling Scheduled Emails

If you have too many emails queued:

1. Go to [Settings / Integrations](https://app.100hires.com/settings/integrations)
2. Click **Cancel scheduled messages** ![Understanding Email Sending Limits: Canceling Scheduled Emails](https://storage.crisp.chat/users/helpdesk/website/-/4/f/a/a/4faab8f2b2ab0400/understanding-email-sending-li_179ecpy.png)
3. All pending emails are cancelled

## Best Practices

* Start with conservative limits for new accounts
* Increase gradually based on deliverability
* Use warm-up for cold outreach accounts
* Monitor bounce rates
* Split high-volume campaigns across accounts
* Check email stats regularly

## Signs of Problems

Watch for:
* High bounce rates (>5%)
* Low open rates (<10%)
* Spam complaints
* Emails landing in spam folders

If you see these, reduce volume and improve list quality.
