Frequently Asked Questions
Are self-seal envelopes as secure as lick-and-stick for bulk mailings?
Yes — quality self-seal (peel-and-stick) adhesives create a permanent bond that is quicker and more sanitary for bulk work. Look for descriptions calling out tamper-resistant or heavy-duty adhesive, and test a few before sealing hundreds.
Will these envelopes work with my home printer?
Most paper-based A2 and A7 envelopes in this roundup are compatible with inkjet and laser printers, but always check the product notes and your printer manual. Poly and padded mailers generally don’t feed well through standard home printers.
Should I choose paper, poly, or padded mailers for Mother's Day cards?
Choose paper envelopes for flat, traditional cards and easy addressing; choose poly mailers for waterproof, tear-resistant protection and a branded look; choose padded bubble mailers when cards include fragile or dimensional elements that need cushioning.
