Customer guide
A short guide to using what Firmspotter shows you lawfully. You, and not us, decide whether to contact somebody and what to say, so the rules about contacting people apply to you.
Last updated 10 November 2026. Version 2026-11-10.
Contact businesses only
Firmspotter is for business-to-business outreach. Do not use it to contact people in their personal lives, and do not use the people it shows you to market to consumers. The terms forbid both.
Every email needs a way out
- Say who you are in every email, and give a clear, free way to say no, such as a reply or a link.
- When someone says no, stop at once and keep a note, so you do not contact them again.
- If somebody asks you to delete them, do it. In Settings, under Data, you can enter their email address: we delete them from your account and never show them to you again.
Sole traders and some partnerships need consent
The rules for emailing a company, a limited liability partnership or a public body are lighter than the rules for emailing an individual. A sole trader, and most ordinary partnerships, count as individuals. You need their consent before you email them for marketing. If you are not sure what kind of business somebody works for, check, or use another way to reach them.
Install the script the right way
- Put the script in your marketing or analytics cookie category, so it only runs after a visitor has agreed to it.
- It does nothing when a visitor’s browser sends a Global Privacy Control signal, and you should not work around that.
- Add our wording for your privacy and cookie policies to your website, and fill in your details.
Be honest about what you know
- The people we show are labelled “likely interested”. That is a guess from a company’s visit and a person’s job. Never tell somebody you know they visited your website, and never imply it.
- Treat the suggested message as a first draft. Read it, and change it so it is true and sounds like you.
- Do not send messages on LinkedIn by machine. Use the LinkedIn note we suggest as something to paste yourself.
What you must not do
- Do not enter sensitive personal data (health, beliefs, politics, trade union membership, and so on) into the service.
- Do not use anything you learn here to decide about a person’s job, credit, insurance or access to a service.
- Do not resell, publish or share the contact details you are shown.
