Make Your Mail Matter: Custom Printed Envelopes That Impress

In today’s world of emails and DMs, sending something in the mail might feel a bit… old school. But when it’s done right? It stands out—especially when it arrives in a beautifully branded custom envelope.

At Dumont Industries, we pride ourselves on being one of the most price-competitive companies offering custom envelope printing throughout Australia. We print an extensive range of envelope sizes, types, finishes, and closures—whether you're after business basics or eye-catching marketing material.

And yes, we’ve got design services too. Whether you have existing artwork, a rough idea, or just want us to take care of the whole thing—we’re here to make the process easy.

Why Go Custom?

Branded envelopes aren’t just about looks (although, let’s be honest, they do look sharp). They serve a real business purpose too:

• They give a professional first impression.
  Before someone even opens your mail, they’ve already formed an opinion. A crisp, customised envelope says you’re the real deal.
• They stand out in the mail pile.
  Make your letters, invoices, marketing materials or promos impossible to ignore with colour, clever design, or even a bold finish.
• They carry your brand further.
  Every piece of communication is an opportunity to reinforce your brand. A branded envelope continues your identity across every touchpoint.

Here’s a quick guide to the most popular options you can choose from:

📏 Common Sizes:

• C4 – Fits A4 sheets flat, no folding needed.
• DL – Fits A4 folded into thirds (standard business size).
• DLX, C6, C5, C3, B4, B5, 11B – These are popular for invites, marketing, postcards, and other creative uses.

📬 Closure Styles:

Need privacy?

Opt for Secretive envelopes—they have a blue printed pattern inside so the contents stay hidden, perfect for sensitive or financial documents.

Tips for Designing a Standout Envelope

Designing your envelope can be simple or snazzy—it’s up to you! Here are a few tips to help you get the most from your print:

1. Match your brand.
Use your logo, brand colours and fonts to create consistency across your stationery suite.

2. Keep it clean.
Too much clutter can be confusing. Let your branding breathe and keep it simple where you can.

3. Use both sides.
The front is functional—but the back flap is a great spot for a tagline, logo, QR code or a little surprise message.

4. Add some flair.
Coloured envelopes, premium finishes, bold text or a full-bleed image? Don’t be afraid to get creative—especially for marketing campaigns.
