Envelope Options
#10 Window Envelopes
Standard business size (4-1/8" × 9-1/2") with a clear window that shows the recipient's address printed on the letter itself. The most cost-effective option for high-volume mailings — no separate envelope addressing needed.
Closed-Face Envelopes
No window — the address is printed directly on the envelope. Gives a more personal, hand-addressed appearance that typically generates higher open rates for marketing and fundraising mail.
Custom Envelope Printing
Need envelopes printed with your logo, return address, or custom branding? We can print custom envelopes in a range of sizes and colors. Branded envelopes reinforce your identity and improve open rates by making your mail immediately recognizable.

Why Physical Letters Still Work
Higher open rates than email
Physical mail is opened by 80–90% of recipients, compared to 20–30% for email. A well-crafted letter in an envelope demands attention in a way that an inbox notification simply doesn't.
More trusted than digital
Consumers consistently rate physical mail as more trustworthy than email or digital ads. For financial statements, legal notices, and fundraising appeals, a physical letter carries authority.
Longer shelf life
Physical mail sits on desks and kitchen counters for days or weeks. An email is gone in seconds. Letters with account information, renewal dates, or offers are kept and referenced repeatedly.
Complements digital campaigns
Combining a letter campaign with email, social media, or online retargeting (via our MMScope platform) can boost overall response rates by up to 46% compared to any single channel alone.
