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