When we test something, we write it up with the method and the numbers, so you can check the work and cite it.
A column per sender name by overall reply rate: 2.5 to 3% for Elizabeth, Olivia, Mia, Rachel and Anna, about 5% for Bob and Gerald.
For 60 days we emailed US small businesses from 140 inboxes, 20 for each of seven sender names. Bob and Gerald got 1.7 to 2 times the reply rate of the five female names, and Gerald's inboxes brought in 3 of every 5 positive replies.
US cold outreach, a column per sending day by reply rate: about 2.5% on weekdays, about 6 to 7% on Saturday. Sunday is drawn at weekday height, as the study reports it as broadly similar.
For more than a year we emailed US small-business owners on weekdays and on Saturdays, at about 50,000 emails a day either way. Saturday's reply rate was more than twice the weekday rate. In six Western European countries, weekend reply rates were lower.
Pairs by days of warm-up. A cube is about 15 days of account life once sending began. Dashed where the study has no group figure, and where the accounts lasted longer than drawn.
We tracked 1,800 new Gmail accounts through 7, 14 or 30 days of warm-up, with half of them starting on people who had replied to us before. The accounts that warmed up longest and started with those people stayed out of spam the longest.
The groups, the setup and how we measured the result, laid out so you can check it.
Figures from our own sending, each one marked as an average, a range or a single report.
Every chart downloads as an image with its source line, ready for your own deck or post.
