It depends on your marketing needs and the type of service you want to use, to make it happen we work on the ideal arrival date to determine your best day of the week. Most mailings will get better results if the mailer is received at home during the mid-week (Tues/Wed/Thurs) because your prospects are usually busy over the weekend and tend to ignore direct mail pieces during these times. If you are mailing to local addresses via Marketing Mail, we can drop ship your pieces on Friday at either SCF or NDC location, and the mail will be delivered in 2 to 4 days. Please note that drop shipment will not be possible for all mailers. We will advise you if it benefits you on your specific mailing.
