Best day to send emails differ in B2B and B2C markets

According to research by eRoi:

• B2B email recipients prefer to receive messages on Tuesday (36%) and Monday (33%)
• B2C email recipients prefer Friday (31%) and Wednesday (26%).

The highest click rate (6.2%) is around the lunch hour and the second-highest click rate is at 10am, with 5.9%.

Another interesting difference is:

• Nearly 8 of 10 B2B email recipients subscribe using their business address.
• However, only 57 percent of B2C email recipients subscribe using personal email addresses; 24 percent use an address created for email lists; 19 percent use their business addresses.
