GrowthHackingIdea - +100% to response rate (cold emails)
Researchers blasted cold emails to 1,000 of the busiest business people in America: C- and VP-level executives from the Fortune 500 and the Inc 500.
They A/B-tested 2 different subjects and the same body:
1. "Quick Question"
2. "15 Second Question for Research on Annoying Emails"
Results.
The open rate was almost the same: ~50%.
But! By over-promising on the time commitment with the "15 Second" subject line, they turned some recipients off. As a result, reply rates were very different:
1. "Quick Question" — 66.7% of total replies
2. "15 Second Question ..." — 33.3%
That’s a TWO times difference.
