Do you need a dedicated IP to send emails with SleepPRO™?

Most members do not need a dedicated IP. Here is how sending works in SleepPRO™.

1. IP reputation

Email providers such as Gmail and Outlook give every sending IP address a reputation score, based on its history. A high score helps emails reach the inbox. A low score sends them to spam, or gets them blocked.

2. Shared or dedicated IP

• Dedicated IP: used by one sender only, who builds its reputation from zero.
• Shared IP: used by many senders. SleepPRO™ sends through shared IP addresses, which are actively monitored to keep their reputation high.

For most members, shared IPs give the best deliverability, because they come with an established good reputation.

3. The sending pools

Senders are grouped into five pools based on their results:

• New user: the starting pool for new accounts.
• Low risk: excellent results.
• Moderate risk: average, acceptable results.
• High risk: poor results, kept apart to protect others.
• Quarantine: a temporary pool for senders whose activity could harm the network.

Good senders enjoy a high-reputation environment, and poor senders are kept apart until they improve.

4. What decides your pool

• Low risk: open rate over 20%, spam rate under 0.25%, bounce rate under 0.7%.
• Moderate risk: open rate 10% to 20%, spam rate 0.25% to 0.4%, bounce rate 0.7% to 1.8%.
• High risk: open rate under 10%, spam rate 0.4% to 1%, bounce rate 1.8% to 5%.
• Quarantine: spam rate over 1% or bounce rate over 5%.

5. Moving between pools

Pools are updated daily:

• You stay in a pool at least 14 days before you can move.
• You need to send a minimum number of emails before your results are reviewed: new user 500, low risk 5,000, moderate risk 5,000, high risk 5,000, quarantine 1,000.

This keeps your pool based on steady, long-term habits instead of one-off ups and downs.
