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 for the addressee. The result is opening rates of practically 99%. Ordinary mail uses printed addresses. Such envelopes disappear on the pile with other mail.  A handwritten envelope proves impressively that the sender is aware of the importance of such details. That's why hand addressed envelopes massively improve direct mail response rates.

Type: Envelope1S 

Recipient Addressing Only

In the case of our Envelope1S format, only the recipient's address is written on the envelopes or labels. The sender's credentials are either printed on the envelopes or omitted.

"Hand-addressed envelopes gleaned almost three times as many responses compared to printed labels."
