How Can I Make a Self-Addressed Stamped Envelope?
Prepare an empty, unsealed envelope with your name and address clearly printed on the front as the addressee, add appropriate postage, then stick it inside the packet or letter that is being sent to the recipient. A self-addressed stamped envelope, or SASE, is a professional business tool that makes it simple and free for a prospect to return a document.
Write your address
Write your business address on the envelope just as you would to mail a letter to yourself. For a more professional image, set up the printer to type the address in the center of the envelope. Include the targeted recipient's name on the top line, followed by the company name and mailing address.
Stamp the envelope
Add the correct postage to the envelope. While companies sometimes send SASEs without postage, prospects and clients may perceive this as tacky. The cost may deter a reply as well.
Fold the SASE
When sending a large envelope with materials, place the envelope inside. In a letter-sized envelope, fold the SASE in thirds by making two creases, according to writer Megan Spooner. The address side should face out toward the recipient.
Package and mail
Seal up the mailer with the SASE enclosed. Address the external envelope with the name and address of the targeted recipient. Add the correct postage. Drop the envelope in the mail.
