Why professional letters work

Premium letters that command attention.

Get the open rate of personal mail and the substance of a real business letter. A #10 envelope, a live stamp, and handwritten-or-typed addressing get it opened; a full 8.5″ × 11″ page on your letterhead gives you room to tell your story, establish credibility, and drive a response — all in a piece that looks like it was meant for one person.

📮

Questions

Before you order

What's the difference between Professional and Personal Letters?
Professional Letters are a full 8.5″ × 11″ letter on your letterhead, mailed in a #10 business envelope — room for a complete message, your branding, and detail. Personal Letters are a shorter note in a smaller A6 invitation envelope, built to look like fully personal mail. Choose Professional when you need space to make the case; choose Personal when you want the most personal-looking piece.
Can I use my own letterhead and branding?
Yes. Upload your own logo or choose one of our branded letterhead styles so the letter looks like it came from your business. You can also set the body and envelope in a typed or handwriting-style font — 8 fonts in total, including 5 realistic handwriting options.
What's the difference between First Class and Standard?
First Class delivers faster (generally 1–5 day delivery) and returns undeliverable mail, which keeps your data clean. Standard Class costs less per piece and takes longer to deliver (generally 5–20 day delivery).
Can I use my own list?
Yes. Upload your own list or have us build you a targeted mailing list. Every order runs through NCOA and address verification before printing so you're not paying to mail bad addresses.
How fast will my order mail?
Orders mail within 3 business days of proof approval. Larger or recurring programs can be scheduled — talk to us if you need a specific in-home date.
Is there a minimum order?
The minimum is 200 mailers. Need to send fewer? Open Letter Connect lets you trigger one-off and low-volume letters on demand — no minimum. Per-piece pricing here drops as volume increases; see the volume pricing table above.
