Handwritten Envelopes Maximize Open Rates

If your message is sent in an envelope with a handwritten address, it stands out 100% within the mail stack. Such envelopes make the recipients curious because these envelopes express esteem towards the addressee. As a result such envelopes are practically always opened. Mediocre direct mail campaigns use printed addresses.
