Unsegmented blast campaigns reply at 2.8% vs 11.4% for tiered lists

Unsegmented blast campaigns reply at 2.8% vs 11.4% for tiered lists

Across 1,200 outreach campaigns (n=1,200, 12-month window), the volume trap is sending one template to everyone.

Reply rate by approach:
— Single template, unsegmented: 2.8%
— Segmented by site type + personalized first line: 11.4%

The lift comes almost entirely from the opening line referencing the recipient's actual content. Generic merge-tags (first name only) move the needle by under a point.

Segment prospects into 3-4 buckets by site type and intent, and write the first sentence per bucket — not per send.
