# Warm-up Sending

New domains or IP addresses may be considered suspicious by ISPs until they have established a good sender reputation. To improve email deliverability, it is important to gradually warm up the IP/domain/reputation by increasing the volume of sends while ensuring that emails are delivered normally.

Warm-up is a process that takes time and requires careful consideration of recipients, frequency, and content. During the warm-up process, it is important to monitor email returns and adjust sending strategies as needed to ensure normal email delivery. Here are some key factors to consider:

* Target recipients: Only send emails to those who have opted in, especially those least likely to complain or bounce.
* Email frequency: Keep the frequency of email sends at an appropriate level, avoiding sending too many emails too quickly.
* Email quality: Ensure your emails are of high quality and avoid sending illegal or spam emails.

By following these guidelines, you can successfully enhance your IP/domain reputation and improve your email deliverability.

## Warm-Up Recommendations

We recommend following a simple 14-day plan. The daily send volume is shown in the table below.

| Day | Daily Volume |
| - | - |
| Day 1 | 200 |
| Day 2 | 500 |
| Day 3 | 1000 |
| Day 4 | 2000 |
| Day 5 | 5000 |
| Day 6 | 10,000 |
| Day 7 | 14,000 |
| Day 8 | 20,000 |
| Day 9 | 25,000 |
| Day 10 | 35,000 |
| Day 11 | 50,000 |
| Day 12 | 80,000 |
| Day 13 | 130,000 |
| Day 14 | 200,000 |

If the email deliverability rate is below 85%, it is recommended to revert to the previous day's sending speed to ensure a higher success rate.
