How to Keep Your Franked Mail Neat, Professional & Protected in Transit

To keep franked mail neat, professional, and protected, use envelopes designed to pass through your franking machine, print on a clean flat surface for a clear impression, keep the print head and ink topped up to avoid smudging, protect fragile or bulky items with padded or double-wall packaging, place the frank in the top right corner, and post on the same day it is franked. These simple steps ensure every item arrives looking its best.

In business communications, first impressions matter, and your mail is often the first physical contact a client has with your company. Whether you send invoices, contracts, promotional materials, or customer orders, it is vital your franked mail arrives looking clean, professional, and protected.

At Mailcoms, we help businesses nationwide maximise the impact of every piece of outgoing mail. Here is how to ensure your franked mail maintains its quality from mailroom to recipient.

Use the Right Envelopes for Franking Machines

Not all envelopes are made for going through a franking machine. Padded envelopes, for example, will not fit through the feeder, whereas gummed envelopes will. Forcing items that are too thick through the franking machine can damage it, so always use envelopes designed for franking. We recommend:

• High-quality peel and seal options – easy-to-seal envelopes make folding and inserting a breeze.
• Franking machine compatibility – always check the envelope will fit through the machine’s feeder, which is listed in the franking machine specifications.
• Meter envelopes – use meter posting envelopes when you need to send franked mail in bulk with Royal Mail.

Always Print on a Clean, Flat Surface

Franking impressions can smear or fade if applied over creases, folds, or textured surfaces. For best results:

• Ensure envelopes are clean, dry, and flat before feeding them into the franking machine.
• Avoid overfilling the envelope, which causes bulging and uneven surfaces. If an envelope is overfilled, use a franking label instead.
• Keep your franking labels or direct print areas away from folds or flap seams.

Pro tip: for parcels or bulky items, use franking labels instead of printing directly onto uneven packaging. Find out more about franking labels here.

Ensure Clear and Smudge-Free Impressions

A smudged or faint franking impression can delay delivery due to readability issues or cause problems with sorting. It is easy to avoid:

• Clean your franking machine’s print head regularly (usually weekly or as prompted) to ensure smooth franking.
• Replace ink cartridges before they run low – do not wait for the print to fade.
• Use a soft cloth to wipe the feeder and tray so dust, paper, or glue does not affect print quality.

See our guide on franking machine maintenance for more tips.

Use Protective Packaging Where Needed

Fragile or bulky items need extra care, as they can be easily damaged in transit. Whether you are sending documents, promotional materials, or fragile products, the right protective packaging ensures your mail arrives in excellent condition. Poor packaging can lead to creases, tears, or product damage, so be proactive:

• Use padded envelopes for smaller items such as USBs, jewellery, or components.
• Use cardboard envelopes for important items such as certificates, prints, or photographs.
• Secure boxes with quality packing tape and void fill such as zigzag shredded paper.
• Consider double-walled cardboard boxes for heavier or fragile goods, as they offer superior strength and crush resistance.
• Consider warning printed tape or fragile labels for anything delicate.
• Apply franking labels to larger items so you benefit from the lower franking rates.

Every item you despatch should look like it left your office with care and precision – because it did.

Use the Correct Postage and Positioning

Applying accurate postage saves money and prevents delays or returns. Placing your franked impression in the correct position also helps Royal Mail process your items quickly:

• Check the weight and size of your item using your franking machine’s built-in scale and a Mailcoms Royal Mail size guide.
• Place the franked impression or franking label in the top right corner of the envelope or parcel.
• Avoid overlapping the franking mark with any tape or stickers – it must be visible at all times.

Prepare Your Franked Mail Properly Before Sending

Preparing your franked mail correctly for Royal Mail is important. To do so:

• Group letters or parcels by class and service.
• Use pouches or mailing bags (provided by Royal Mail) to clearly distinguish the class and services being used.
• Post franked mail the same day it is printed to avoid Royal Mail refusing the item due to incorrect dating.
