However, defining the best time for sending out cold emails is a real challenge. Even after using the best email automation tools of the century, cold emails remain bleak for maximum B2B marketers. The reason is simple- it's the emailing timing. 

Then, what should be the best time to send out the B2B cold emails?

As a B2B marketer, you have probably pondered over the issue of defining the best time for cold emails a million times.

Tuesday and Thursday still retain the top position for cold emailing among B2B marketers. Fridays are a good choice too. However, the trendline falls during Saturdays and Sundays, rendering them the worst time for cold emails.

It also represents the work schedule of an average B2B marketer. After dealing with the mayhem of the opening day, they sort their inboxes on Tuesdays. It continues more or less for the rest of the week. However, only a few people are found to be active in their mailboxes during weekends.


We declare Weekdays as the winner for sending out cold emails. Maximum people are known to avert their professional lives on weekends. It's the same for your B2B clients too! Therefore, avoid cold emails during Weekends like the plague.
