A CEO email signature that matches the rest of the company
The founder's signature uses the same logo and layout as everyone else's, with their own name, title and photo, and the executive assistant's signature next to it.
What to include
- Name and title, such as Founder and CEO.
- The company name, logo and layout the rest of the company uses.
- A direct phone or an assistant's contact for scheduling.
- For a UK company: registered name, number, place of registration and office address in the footer.
- Directors named in the footer only if every director is.
What UK company law says about directors in an email signature
For companies registered in the UK. These are the primary sources, quoted or summarized. Signatoro is not a law firm, and this is not legal advice.
- SI 2015/17, regulation 26(1): "Where a company's business letter includes the name of any director of that company, other than in the text or as a signatory, the letter must disclose the name of every director of that company." SI 2015/17, regulation 26
- Regulation 25: business letters, order forms and websites show the part of the UK where the company is registered, its registered number and its registered office address. SI 2015/17, regulation 25
- Regulation 29(c): a reference to a type of document "is a reference to a document of that type in hard copy, electronic or any other form", so the rules reach email. SI 2015/17, Part 6

The founder's signature is the company's signature
A CEO writes to investors, customers and new hires. On Signatoro the founder's signature is built from the same company settings as everyone else's, and an AI assistant that drafts for the CEO fetches that signature at send time.
