Is there a best time and/or day of week, to send an email blast to your customer list?
I've just had an associate speculate that it's best to blast during working hours. The thought is that if someone comes in on Monday and there are a couple dozen emails from the weekend, there is more of a chance that they will not look them. People will be more likely to read an email that comes in during their working hours.
Is this true? Does it matter when the email is sent?
