How nonprofits and charities use this envelope

Use them for invoices, thank-you notes, gift certificates and mailings. Worth including: what each donation achieves.

Show one specific outcome (for example meals served) rather than general statements. Print a small batch first and run one through your printer to check alignment.

What to put on it

  • Logo and return address in the top-left corner
  • Clear space for the recipient's address and postage
  • Optional short message on the back flap
