  • Handle the envelope as little as possible. Every little bend, tear and dent will make it look as though it was tampered with.

Steaming Open an Envelope

This is the method most people have heard of because it has been featured on tons of sitcoms where teens need to check something the school sent to their parents before their parents read it. In reality, this method should ideally only be tried if freezing fails because it’s possible the steam may warp the envelope paper and the contents inside. If the paper is too wet, be sure to lay it on a flat surface to dry.

The source of steam can be just about anything, but most people find the steam from a kettle or a mug filled with freshly boiled water to be the easiest to work with. Some people claim that using an iron on low heat with the steam on is actually more effective as there’s less moisture, reducing the chance of water damage. Once things start to loosen up a bit, use a knife to gently pry the flap up, using more steam if you notice any resistance.

To reseal the envelope, use a glue stick or liquid glue applied to a cotton swab, as the steam method does make the glue on the envelope no longer usable.
