According to a report done by MailerMailer, email marketing campaigns that are sent in the early hours of the morning, have a higher percentage rate of opening, compared to the messages sent in the afternoon. Wonder why this occurs? It is usually that people read their emails first thing in the morning between 06:00 am and 11:00 am. We also show that on Tuesdays, Fridays, and Sundays are when most emails are read.
"Sundays, generates the largest amount of opening (12.2%) and clicks (4.4%) on average, compared with the rest of the week," the report said.
