Frequently Asked Questions
Do I need bubble wrap for greeting cards?
Bubble wrap adds a thin protective layer that prevents creasing and edge damage. For single flat cards, a single layer plus a rigid mailer is usually enough; for cards with embellishments or inserts, add bubble wrap to reduce damage risk.
Are corrugated mailers better than padded envelopes?
Corrugated mailers generally offer better crush resistance and are a smart choice if cards are valuable or shipped in batches. Padded envelopes are lighter and cheaper to mail, but offer less rigidity—pair padded envelopes with a cardboard insert for best results.
What should I expect from budget mailers?
Budget options typically give good value but may require more assembly and pairing with separate cushioning. Expect variability in material thickness; choose trusted sizes and add a layer of protection if the mailer feels thin.
