The Ultimate Franking Machine Guide

A franking machine is your key to cheaper postage for your business.

If your business deals with large quantities of outgoing post, you will know that sifting through all of this can be a laborious and time-consuming process. That is, of course, if you don’t have a franking machine.

But what is a franking machine? How do they work? And what can they do to save you time and money? 

Well, today, we’re going to answer all that and more. So strap yourselves in as we take you through everything you need to know about the exciting world of franking machines! 

What is a Franking Machine?

Franking machines, sometimes known as postage meters, are feed-in devices that print a mark or a ‘frank’ directly onto mail. This can be a letter, a postcard, a parcel or anything else you can send in the post.

The frank is printed directly on the mail instead of a traditional stamp. This allows you to access Royal Mail’s franking rates, which are cheaper than standard postage. For example, a first-class stamp will cost you £1.35, whereas the franking equivalent is only £1.06, 29p cheaper. 

Yes, this might not seem like a massive saving on the surface, but let’s zoom out. If you post 1000 pieces of mail weekly, that’s £15,080 saved on postage costs each year! 

They also help streamline your operations by automating mundane tasks. 

No more driving back and forth to the post office, waiting for old Mrs Battersby to rummage through her purse for the exact change. No more hours wasted sticking stamps to individual pieces of mail. 

Instead, it’s all done in-house and within your machine, automatically printing the frank on the mail at a faster rate. 

You’re then billed the correct amount based on weight, size and location. This comes directly from a pre-paid account that will often be topped up via an online portal.

Key Components of a Franking Machine

Although each franking machine is different, most will come with the following basic features. 

Connectivity

How will your franking machine connect to the internet to get the latest Royal Mail rates? All can communicate via a LAN connection, while many newer models also have Wi-Fi options.

Feeding System

This is where your post will be fed into your machine. It can be done manually, which, although slower, is suitable for those with lower mailing volumes. On the other hand, an automatic feeder allows for faster processing of larger batches, perfect for bigger operations.

Weighing Scales

The integrated scales guarantee that each item is accurately weighed and the correct funds are withdrawn from your account. This prevents over or underpaying. Basic models process around 2 kg, while more advanced models are up to 30kg. 

Reporting Capabilities

Franking machines offer great insight into your business activities. They allow you to track department usage and expenses, which can be a great cost-saving tool.

Integration with Business Systems

Advanced franking machines can integrate with software you already use, which can streamline your mailing processes.

What is Mailmark Technology?

Mailmark technology is a cutting-edge barcode system developed by the Royal Mail for newer franking machines. This is what is printed on your post instead of traditional stamps, making them more easily trackable. These codes contain important information about the sender, recipient, postage paid, and other relevant details.

A few advantages of using Mailmark technology include: 

Cost Efficiency: 
Mailmark provides the lowest available postage rates, helping you to reduce your mailing expenses. With extra discounts for high-volume mail, it’s the perfect choice if you send out large quantities of post.

Enhanced Productivity:
Mailmark’s streamlined technology processes mail faster than traditional franking systems, reducing staff workload and saving valuable time that can be focused elsewhere.

Precision:
With accurate pricing and processing for every mail item, Mailmark minimises the risk of overpayment or underpayment, helping you avoid penalties and ensuring timely deliveries.

Real-Time Tracking:
Mailmark’s advanced tracking system offers full visibility over your mail. You can monitor delivery progress, confirm signatures, and see when items are processed by Royal Mail.

Professional Appearance:
Mailmark produces high-quality, professional barcodes and labels that enhance your credibility and brand image, setting you apart from your competition.

How Does a Franking Machine Work? A Step-by-Step Guide

Step 1

Weigh Your Mail

Ok, so first things first. Place your items on the built-in scales. This calculates the exact weight of your post and the correct costs.

Step 2

Select Your Service

You’ll need to select two things using the franking machine’s screen and navigation menu. The size of your post and the service (i.e. first or second class).

Step 3

Add Your Message

One of the great benefits of franking machines is their ability to customise your frank. This can be a message to your customers for a personalised touch or just your company logo for a slicker appearance.

Step 4

Calculate Your Costs

Now it’s time to bring together steps 1 and 2. You’ve got your post’s exact weight, size, and location, so let’s total the costs. This is automatically deducted from your pre-paid account. 

Step 5

Print Your Franks

Letters, postcards, parcels, or whatever it is you’re sending out, it’s time to get them franked! This will apply to the following:

  • Postage amount
  • Date
  • Company logo/personalised message
  • 2D bar code
Step 6

Post Your Mail

You then post your mail like you would normally, but with one difference. Instead of using regular post boxes you now get to skip the queues and use special franking post boxes or drop-offs.

Benefits of Using a Franking Machine

Reduced Postage Costs

One of the main advantages of switching to a franking machine is benefiting from reduced postage costs. Let’s have a quick look at the difference between sending a letter via a franking machine and sending a stamp.

First Class Stamp: £1.35
First Class Frank: £1.06
Savings: 29p 

Second Class Stamp: 85p
Second Class Frank: 69p
Savings: 16p

These savings might not look like much on the surface, but remember that this is per letter. The more you send, the more you save. So let’s say you send 1000 letters a week; these are the savings you can expect: 

First Class Savings: £15,080

Second Class Savings: £8,320 

For smaller businesses, these savings can be absolute life savers when managing your budget. All because you did something as simple as switch to a franking machine.

Enhanced Efficiency 

How many hours do you think you’ve wasted going to the post office, lining up, driving back and then sticking a bunch of stamps on your mail? And that’s without the mundanity of just stamp, after stamp, after stamp, when you could be doing literally anything else. Honestly, is there anything worse? 

Well, that’s all a thing of the past with a franking machine. With a few pushes of a button, it weighs your post and selects the service you want. Then it automatically prints the frank on your mail much quicker than you can by hand. 

Now, you can spend that time doing something more productive. Or, at the very least, something more interesting. 

Customisable Printing

The ability to customise your frank opens up a world of possibilities for your business. 

You can add messages to give it a personal touch for your customers. You can even print any offers or upcoming events, giving you a unique marketing opportunity. Or just use it to stamp your logo for a clean, professional image. 

Increased Security

Without the need for stamps, you’ll no longer have any stamp books lying around waiting to be stolen, lost, or forgotten about. 

Most franking machines will also come with a PIN code that is needed for access, meaning only certain employees can use it and bill to your account. This also applies to accessing any generated reports, such as monthly spending and departments using the machine. 

Generate Business Insights 

As mentioned, you can see which departments use the machine the most and how much is being spent. This can help with forecasting, strategy and even cost-cutting. 

Improved Accuracy 

Because franking machines have built-in scales, you can sleep easy knowing that you’re never under or overpaying for your postage costs. It also goes a long way in improving customer satisfaction, as they won’t ever be in a position where they have to pay to receive anything you send them. 

Automatic Updates 

Franking machines require an internet connection to work. This means they will automatically download up-to-date postage rates and apply them to your post when you use it. No more sitting around with a calculator trying to figure out how much it will cost you this week. 

How to Choose the Right Franking Machine for You

When it comes to choosing the right franking machine for your business, there is no one-size-fits-all option. If you send a couple hundred letters a month, what you need is very different from someone who sends out a couple hundred a day. 

Before taking the plunge and committing to a franking machine provider, ask yourself the following questions. 

How Much Post Do I Send? 

The first and most obvious thing to consider is how much post you send. Just above this section, we mapped out three different franking machines and the level of volume they can handle. 

But it’s not just the amount of mail you post, but also the type. Some machines will be more suited to handling envelopes, while others will be better for parcels. Make sure you consider this, or you will find yourself with an unsuitable franking machine. 

What Type of Connectivity Do I Want? 

Like most pieces of technology these days, franking machines require the internet to work. Most will be connected via LAN (phone line) or Wi-Fi. Depending on your location, one may be better than the other. 

A strong connection is essential regardless of how much mail you want to process. You don’t want to be halfway through a bunch of parcels that need to be out that afternoon for your internet to cut out. Then, you spend the rest of the day manually stamping them. 

If that happens, what’s the point of having a franking machine in the first place?

Do I Want To Rent or Buy?    

Buying or renting your franking machine has pros and cons, and you need to find out which is best for you. Below you’ll find the pros and cons broken down in two tables, the first of which focuses on buying your franking machine.
