Best day for sending emails

Q. Which day of the week is the best for sending out emails?

Are there good days and bad days? Does the same email message perform better if it sent on a Monday, rather than on a Friday?

A. Yes, there are good and bad days.

MON...............15.1%
TUE....................19.6%
WED.......................22.8%
THU....................19.7%
FRI..............13.7%
SAT.....5.0%
SUN....4.1%

Actually as I write this post, today, Monday 23rd January, is the worst day of the whole year! (The BBC reports that Monday 23rd January is apparently the most depressing day of the year. The calculation is based on a combination of the bad weather, fading Christmas memories, failed New Year's resolutions and a general lack of motivation.) Make sure your agency puts this date into their calendar, and avoids it!

Yes, it's true that other factors affect response rates too, but putting those to one side, we are looking for the best day of the week.

Summary: as is our own experience here at TMB (sending out B2B and B2C email campaigns to clients' own lists) the midweek hump peaks on Wednesday.
