Our clients often ask us about what time of what day they should send their email campaigns. We don’t believe there is a correct answer. The best day is unique to your email list and your target consumer. Only over time can you do enough testing to discover for yourself when you achieve the best open rates with your audience.
That being said, there has been some recently released research that reflects some generic averages across many industries and consumer segments. Findings from MailerMailer suggest that Sunday is the best day for open rates and CTR. Tuesdays and Thursdays are also high performing days.
