This is the day you want your mail piece delivered. It is the lightest mail day in the U.S. and having your letter delivered to a busy executive, owner,
purchasing agent, or plant manager, on the day they receive the least mail increases your likelihood of the piece being opened and read.
Wednesday
This is the second lightest day. If you can't hit a Tuesday delivery for some reason, shoot for Wednesday for all the same reasons.
Monday
This is the heaviest mail delivery day in the country. This simple fact may decrease your response rate regardless of the accuracy of the list, the conciseness
of the target company selection, or the correctness of the information.
