Choosing the right envelopes for your franking machine isn’t just about size – it’s about performance, print quality, and security. Using poor-quality envelopes can lead to smudged impressions, machine jams, damaged mail, and even extra postage costs.
At Mailcoms, we supply a wide range of franking machine-friendly envelopes designed specifically for smooth feeding, clean printing, and reliable sealing – ideal for busy mailrooms of any size.

That’s why we only stock high-quality, franking machine compatible envelopes at Mailcoms so that you can post with confidence.
They fit seamlessly into franking machines & folding inserting machines alike, are lightweight for cost-effective postage, and look professional for everyday correspondence.
Great for slightly bulkier letters or brochures that don’t require multiple folds. Their larger surface area still runs smoothly through franking machines without jamming.
Ideal when presentation matters – important documents stay flat and professional-looking. C4 envelopes pair perfectly with larger franking machines equipped for thicker mail.
While standard business envelopes are ideal for direct printing through a franking machine, there are plenty of other mailing materials & envelope types that can still be used – you just need to apply a franking label instead! This opens up your options for mailing different types of items securely and professionally whilst maintaining that professional look. Find out more about franking labels here.
Padded Envelopes, also known as bubble-lined mailers, are great for sending delicate or bulkier items that need extra protection, whilst keeping costs down. Available in multiple sizes and as paper, white, gold or honeycomb options. View our range of padded envelopes here.
