Easy to spot, hard to miss

Printed business envelopes typically look more professional than handwritten ones, while making billing and customer communication a lot smoother. When handling high volumes of post, branded envelopes can save you time and elevate your business image. Our envelopes are also sized to fit Royal Mail’s automated sorting standards. Whether it’s an invoice, thank you note or voucher, you don’t want your envelope to get lost in the post. With sharp printing and a bold design, your business envelopes will be instantly recognisable to anyone familiar with your brand.

Professional & efficient

Our grey security interior makes sure that sensitive information stays protected by preventing people from peeking inside. You can choose between gum or strip seal flaps and take advantage of optional printing on the backside. Options include printing on the sealing flap (ideal for adding a return address), the backside only (excluding the flap) or the entire backside (including the flap). Plus, you have the flexibility to add an address window, logo, images and other elements to grab attention.

Simple design process

Creating your business envelopes is easy. Start by selecting your quantity, size, window option and seal style. Then, click ‘Browse designs’ to explore a variety of templates you can customise with your information, for both the front and back side of your envelope. Our 3D design studio allows you to see and design the envelope as it would appear in your hand. You can then experiment with fonts, spacing and the size and placement of your logo or images. Once you’re happy with the design, preview it and complete your order.
