Most signature generators are tracking tools
Look at what a typical free email signature generator actually gives you and there is usually a small image in it. Sometimes it is your logo. Frequently it is a one pixel transparent square, and sometimes it is both, because the logo is doing the same job.
A remote image is how the generator knows when your email was opened. Every message you send loads it from their server. That is the business model, and you are the distribution.
It has two consequences you did not sign up for. You have put a beacon in every client's inbox, which is a data protection question with no upside for you. And corporate mail filters block remote images by default, which is why so many carefully designed signatures arrive as a red X.
This one has no image at all. Text and inline styles. Nothing to load, nothing to block, nothing that phones home.
Why it looks like 2005 markup
Because a table with inline styles is the only thing every mail client renders the same way.
Classes get stripped. External stylesheets never load. Modern layout is unreliable and degrades differently in each client. Outlook in particular is famously unimpressed by anything invented after about 2003. A table is ugly to look at in the source and completely predictable in the inbox, which is the correct trade for something that has to work in software you do not control.
The legal bit, answered honestly
You will be told confidently that your company number must be in your email signature. You will also be told confidently that it need not. Both are guesses.
Regulation 25 lists business letters, order forms and websites. Email is not on it. Whether an email is a "business letter" has never been settled in the regulation itself, and reasonable people read it both ways.
Regulation 24 is not ambiguous. It puts your registered name on "all other forms of its business correspondence and documentation", and an email is plainly business correspondence.
So: the name is required. The number and registered office are arguable. Adding them costs one line of small grey text and removes the argument entirely, so they are switched on by default here rather than because a rule demands it.
The disclaimer nobody reads
"This email and any attachments are confidential and intended solely for the addressee."
It does almost nothing. You cannot impose obligations on a stranger by emailing them a paragraph, and a disclaimer that arrives after the disclosure has not un-disclosed anything. If you send a price list to the wrong person, the footer does not retrieve it.
It is convention, not protection. Some industries expect it and their customers would notice its absence, which is a genuine reason to keep it even though it is not a legal one. It is off by default here and one click away if you want it.
Paste it as HTML
Copy the block and paste it into the signature editor in Gmail or Outlook. Do not screenshot it.
An image of a signature cannot be searched, cannot be clicked, is invisible to anyone reading in plain text or with a screen reader, and gets blocked by exactly the filters that block tracking pixels. It is the same failure as the thing this tool exists to avoid, arrived at from the other direction.
There is a plain text version below the HTML one for anybody whose client refuses rich text at all.
Common questions
Do I legally have to put my company number in my email signature?
The honest answer is that it has never been settled, and anybody telling you otherwise is filling a gap with confidence. Regulation 25 names business letters, order forms and websites. It does not name email, and whether an email counts as a "business letter" has not been decided in the regulation itself. What is not in doubt is regulation 24, which puts your registered name on all business correspondence, and an email is plainly that. So the name is required, the rest is arguable, and putting it in costs one line.
Why does this generator not add a logo?
Because a logo in an email signature is a remote image, and remote images are how most signature generators track who opened what. That puts a beacon in every recipient's inbox, which is a data protection conversation you did not need to have. It is also why so many signatures arrive as a broken image behind a corporate mail filter. Text and inline styles render the same everywhere and tell nobody anything.
Why is it built as a table?
Because that is what survives Outlook. Mail clients each strip something different from HTML, and a table with inline styles is the one shape all of them render consistently. Classes get removed, external stylesheets never load, and modern layout is unreliable. This looks like 2005 markup on purpose.
Is the confidentiality disclaimer worth including?
It does almost nothing and it is your choice. You cannot impose obligations on somebody by emailing them a paragraph, and a disclaimer sent after the disclosure has not un-sent it. It is convention rather than protection and it makes every message longer. Plenty of businesses keep it because their customers expect it, which is a real reason even though it is not a legal one. It is off by default here.
Should I paste it as an image?
No, and it is a surprisingly common mistake. An image of a signature is unsearchable, unclickable, invisible to anybody reading in plain text, and blocked by the same filters that block tracking pixels. Paste the HTML into the signature editor in Gmail or Outlook and it stays text.
What if I am a sole trader?
If you trade under a business name rather than just your own surname, section 1202 wants your own name and an address for service on your business correspondence. Switch the form to sole trader and the footer changes to match. If you trade as "John Smith" with nothing added, none of it applies to you and the footer is yours to use as you like.
