The hidden cost of in-house mail

When finance teams compare hybrid mail to running their own mailroom, they usually start with the wrong number. The postage stamp is about 85p; Intelliprint charges from 84p including printing, envelope, and postage. At a glance it looks like a wash. It isn't — because the stamp is the cheapest part of sending a letter in-house.

Where the real cost hides

Here's what actually gets spent on each letter that goes out of a typical office, assuming someone prints, folds, and posts it:

• Staff time. Preparing an envelope — retrieving the document, printing it, folding, inserting, sealing, stamping, and handling — takes most people 3-5 minutes per letter. At £30/hour loaded salary cost, that's £1.50-£2.50 of labour per letter. Easily the biggest line item, and the one least often counted.
• Postage. 1st Class stamp: 135p. 2nd Class: 85p. Large letter surcharges apply if your document is over a certain weight or size.
• Envelope. Roughly 3-8p for a standard C5, more for branded or window envelopes.
• Paper and ink. 5-10p per page printed, depending on your setup and colour vs mono.
• Printer costs. Lease, maintenance, toner replacement, occasional service calls — usually hidden in office overheads but real.
• Post office trips. Whether it's a walk down the road or a daily franking-machine pickup, the operational time and occasional queue costs real hours over a month.

Add it all up and a typical in-house letter costs somewhere between £2 and £3.50 once labour and overheads are included — 2-4x the postage-plus-consumables figure most people quote.

Where hybrid mail comes in under

Hybrid mail charges a single per-piece price that includes all of the above except your internal time for the upload itself — which, for a typical ad-hoc letter, is under a minute. Intelliprint letters start at 84p including envelope, printing, and 2nd Class postage.

The real saving isn't the per-letter pence — it's the hours that come back to your team. For an accounts team sending 200 invoices a month at 4 minutes each, that's over 13 hours a month of manual mail prep that disappears entirely. That's the line item that matters.

Run your own numbers

We put a savings calculator on the site that takes a few inputs — monthly mail volume, current labour cost, franking setup — and tells you what the swap to Intelliprint would look like for your business. It's not a sales gimmick; the number it returns is often lower than customers expect on the Intelliprint side too.

If the gap's under £100/month, in-house probably still makes sense for you. If it's £500+ per month, that's a team member's worth of hours going into mail that could be going somewhere else.
