# Envelope Options

### Personal Letter Envelope

A personal letter envelope gives your mail a warm, polished feel. It resembles the type of envelope someone might use in everyday life, which makes it approachable and familiar. That familiarity encourages recipients to open it rather than dismiss it as marketing material.

### Professional Letter Non-Window Envelope

This envelope is all about clean presentation. The address is printed directly on the envelope, creating a uniform and professional look. Unlike windowed options, it removes the sense of “bulk mailing” and instead communicates intentionality. For businesses, this detail can make correspondence feel more serious and official.
