What's the minimum number of weeks you need to warm your IP address before reaching the highest maximum limit?

Warming up an IP address is a crucial process that involves gradually increasing the volume of emails sent from that IP to build its reputation with ISPs. This is essential for ensuring high deliverability rates and avoiding spam filters.

To effectively warm up an IP address, it typically requires a strategic approach over several weeks. The best practice is to gradually escalate the number of emails sent each day, allowing ISPs to recognize the sending behavior as legitimate and consistent.

The recommended duration for warming an IP address is usually around 6 weeks. This timeframe allows enough time to establish trust with ISPs, demonstrating that the sender adheres to best practices in email marketing, such as maintaining low complaint rates and respecting engagement metrics.

While some sources may suggest shorter periods, achieving the highest maximum limit in a reliable manner to ensure deliverability tends to require this duration. Therefore, 6 weeks represents a widely accepted standard for an effective IP warm-up, aligning with established marketing practices in email deliverability.
