Best Day of the Week to Send Direct Mail?

[Ori Skloot]

Hey Folks,

I'm sure this info is somewhere in a previous conversation but I can't find it.  

Does anyone have data on the best day of the week to send direct mail in order to get the highest open and response rate?  I've read different opinions but haven't seen anything concrete.  I've heard: 

• Don't have your mail land on Monday because that is the heaviest mailing day. 
• Try to have the mailer land on Tuesday or Thursday (light mail days)
• Make sure it lands after Wednesday and before Sunday (people are more receptive and happy toward the end of the week)
• Try to get it to land on the weekend (people are more likely to open and call you because they have free time

What had been your experience?
