Staggering email sends is a crucial strategy for enhancing sender reputation and avoiding throttling. This involves gradually increasing sending volume, especially when warming up new IPs or after periods of inactivity, and maintaining consistent engagement. Staggering prevents overwhelming ISPs and triggering spam filters, helping to build a positive sending reputation. Engagement is directly linked to reputation, and strategic ramp-up avoids being blacklisted. List segmentation and careful monitoring further contribute to deliverability.
