What the alternative costsThe supplied tool data gives no price for a human designer or an email-signature service.
If this goes wrong: a detail is incorrect or the signature renders badly, and you can correct it before using it widely.
What to actually do
Do it yourself
The route this page recommends
A chat interface, no skill needed, and roughly 15 minutes until you can act on the result.
How to actually do it
- Open your current brand files and gather the approved logo, brand colours, typeface guidance and any required legal or promotional wording.
- Copy your current name, job title, business name, phone number, email address, website, address and approved social links into the matching slots in the prompt.
- Paste the completed prompt into ChatGPT, Claude or Gemini and ask it to produce the signature text, layout, HTML and plain-text fallback.
- Open the returned HTML in your email provider's signature settings and paste it into a new signature, or use the visual layout as a guide if the provider does not accept HTML.
- Compare every name, number, spelling, logo link and URL against your current business records and open each link in a browser before saving the signature.
- Send test emails to yourself and a colleague using desktop and mobile email apps, then check spacing, image loading, link behaviour, readability and the plain-text version.
- Replace any incorrect or poorly rendered element, save the corrected signature, and send a final test email before applying it to outgoing messages.
Prompt
Design a professional email signature for my business using the information below. Create a clean layout that works on desktop and mobile, uses plain text for important contact details, and does not put essential information inside an image. Use only the facts and links I provide, and do not invent claims, awards or social profiles. Give me: 1) the final signature text, 2) a simple visual layout description, 3) HTML that I can paste into an email signature editor, and 4) plain-text fallback text. Keep it compact, accessible and easy to read. Use my brand colours only where they support legibility, include suitable alt text for the logo, and make every link explicit. Flag anything that needs checking before I publish it. Business name: [BUSINESS NAME]. Name: [FULL NAME]. Job title: [JOB TITLE]. Phone: [PHONE]. Email: [EMAIL]. Website: [WEBSITE]. Address: [ADDRESS, IF NEEDED]. Social links: [APPROVED SOCIAL LINKS]. Logo file or URL: [LOGO FILE OR URL]. Brand colours: [BRAND COLOURS]. Other required wording: [REQUIRED WORDING].
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong
- AI cannot know which brand details are genuinely approved unless you provide them.
- AI cannot judge whether the design feels right for your customers and sector without your brand context.
- AI cannot guarantee that the HTML renders identically across every email client.
- AI can reproduce a logo or link incorrectly, so you still have to compare the result with your source files.
- AI does not decide whether promotional, legal or privacy wording belongs in your signature.
Even on a YES, the friction has a name: taste and context depth.

FAQ
- Can ChatGPT make an email signature?
- Yes. It can draft the wording, suggest a layout and produce basic HTML, but you need to supply the correct business details and test the result in your email apps.
- Can AI create an HTML email signature?
- Yes, for a simple signature with text, links and a logo. Email clients handle HTML differently, so send test emails and fix any layout or image problems before using it.
- What should I include in a business email signature?
- Usually include your name, job title, business name, a reliable contact method and your website, with approved social links or required wording where relevant. Keep it compact and do not add claims, links or personal details that your business has not approved.
- Is it safe to use an AI-designed email signature?
- Yes, for the design and formatting of a straightforward signature. Check every contact detail, link, logo and required piece of wording yourself, then test how it appears before publishing it.
