We’ve learned over the years to send our clients’ email campaigns at different times, on different days, based on their audience.
For example, we send real estate emails on weekends, because that’s when people are off work and ready to go house hunting. B2B emails obviously go out on weekdays. Emails for events, restaurants, and nightclubs go out on Tuesdays and Wednesdays around 2pm so that recipients have time to plan their weekends.
MarketingSherpa just published a case study along those same lines. A company reveals how they discovered that by splitting their list into "home" vs "work" email addresses, and then sending on different days, they could double their response rate.
They included their list of domain names for home addresses. We have a much more thorough list of "home, free, and anonymous" email domains that we use at MailChimp. Let us know if you’d like a copy.
