The consensus on the best IP warmup strategy for weekly email sends on new IPs emphasizes a gradual and consistent approach. Experts and documentation agree on starting with a small volume of high-quality emails to the most engaged subscribers and gradually increasing the volume over several weeks. Closely monitoring deliverability metrics such as bounce rates, spam complaints, and sender reputation is crucial, allowing for adjustments as needed. Maintaining consistent traffic patterns, ensuring a clean email list, and avoiding sudden bursts of email are also key. Some advocate for a faster ramp-up by doubling volumes every few days, provided that diligent monitoring enables quick adjustments. Furthermore, considerations such as throttling sends based on SMTP layer and list composition, varying send days to distribute traffic, ensuring valuable content, and addressing potential conflicts between content rules and sending schedules are highlighted.

The optimal IP warmup strategy for weekly email sends on new IPs involves a gradual and consistent approach to building a positive sender reputation. Experts recommend starting with low sending volumes to only the most engaged recipients and gradually increasing the volume over several weeks, while closely monitoring deliverability metrics like bounce rates, spam complaints, and sender reputation. Consistent traffic patterns and clean lists are crucial. Throttling sends and adjusting based on MTA responses and list composition can also optimize deliverability. Varying send days and prioritizing valuable content are further suggested. Some advocate for a faster ramp-up doubling volumes every few days, provided monitoring allows for quick adjustments.

Experts emphasize the importance of establishing a good sending reputation when warming up new IPs, which requires a gradual increase in sending volume to engaged recipients over several weeks. Consistent sending volumes are crucial for building a predictable and trustworthy sending pattern for mailbox providers. Potential conflicts between email content rules and sending schedules should be addressed by prioritizing policy changes with relevant parties.

Official documentation consistently emphasizes a gradual IP warmup process as crucial for new IPs. This involves starting with small volumes of high-quality emails sent to engaged subscribers and progressively increasing the volume over several weeks. Monitoring sender reputation, engagement metrics, delivery issues, and bounces is essential. Avoiding sending to unengaged or purchased lists and preventing sudden bursts of email are also critical to avoid being flagged as a spammer.
