Do you think it matters if you schedule them for specific days even?
Some marketers do and others don't. I think it does matter as I look at my own behavior for sending and opening emails.
I like to send them out for 4:am in case they check their email before going to work.
Send on weekdays a few times a week unless their is something special, or there's a news break.
I don't like to send them on a Monday.
At times I also like to send them on a Sunday morning because they may be willing to read through and purchase.
Saturday is no good, I don't like to send out because I figure they won't have time with shopping and other chores.
What do you guys think? :p
