Brand governance: why the signature is your weak point

Every organisation has brand guidelines, an approval process for its assets, and often a person whose job that is. A sales brochure does not go out without review. A client presentation follows a template. A social media post goes through communications.

And the email signature, which goes out several hundred times a day to your customers, your prospects, your candidates and your suppliers, is composed by each person on their own.

The anomaly, in figures

A hundred-person company sends in the order of 300,000 emails a year. That is more impressions than most of its paid campaigns, and roughly the only brand surface that reaches all of its correspondents, including those who will never visit its website.

It is also the only asset whose real state is unknown. Ask the communications department: they know how many brochures exist, and in which version. They do not know how many different signatures are circulating under their logo.

Why this point escapes governance

Three reasons combine, and none of them is technical.

The perception of a personal object. People say “my signature”, not “the company’s signature”. That possessive does everything: nobody would think of letting every employee redesign a brochure, everybody finds it normal that they compose their signature.

The absence of an owner. Communications considers it an IT subject — it is about configuring an email client. IT considers it a communications subject — it is about brand guidelines. The subject stays between the two.

Invisibility. Nobody sees their own sent messages, still less other people’s. The inconsistency is perfectly visible from outside, and invisible from inside.

The four symptoms to look for

They can be observed in an hour, with the sample described in standardising signatures.

Several versions of the logo. The old brand survives a long time. You routinely find two or three generations of logo circulating simultaneously, five years after a refresh.

Diverging layouts. Fonts, sizes, colours, order of information: as many variants as there are people who copied a colleague’s signature at some point.

Missing or expired legal notices. A head office address that changed, an old company name, a mandatory notice missing for the most recent joiners.

Ghost signatures. Those of departed employees, still active on shared mailboxes — see an employee’s departure.

What that laissez-faire really costs

The direct cost — the time spent managing all this by hand — is easy to quantify, and it is significant: see what manual management costs.

The brand cost is harder to measure, and probably higher. An organisation whose signatures diverge sends a signal of dispersion to each of its correspondents. The signal is weak, but it is repeated hundreds of thousands of times a year.

The opportunity cost is the third, and the most tangible for a marketing director: the channel exists, it is free, and it carries no message. That is what the campaigns and banners page addresses.

Bringing the signature back into scope

Three decisions are enough, and none of them is technical.

Name an owner. A role, not a person. In practice communications, with IT’s support for enforcement and HR’s for directory data quality.

Write a short policy. Two pages, covering what the tool does not settle — the model is in email signature policy.

Put an enforcement mechanism in place. This is the decisive point. A policy without a mechanism is an intention: its compliance rate degrades within the first weeks. A locked template, applied by the service from the directory, makes the gap structurally impossible.

Worth knowing: the best argument at board level is not a pitch, it is a board. Twenty real company signatures, side by side, captured as they went out to customers. The discussion about whether the project is worthwhile does not then last long.

The right horizon

Once the mechanism is in place, the signature stops being a governance subject and goes back to being what it should have been: a controlled, current asset that updates itself, and on which you can build — because a consistent channel is a usable channel.
