How we research this Report an error

SignalHire is a company that offers a searchable database of people, plus a browser extension and an API. Its site lists tools such as a personal email finder, a social media email finder, a phone number search and a social media lookup. The company says in its opt-out notice that it obtains and indexes publicly available information, and that it also processes data of its own users and customers.

Why you might care

Tools like this are built for recruiters and sales teams who want to reach a person directly. If you have a profile on a public site, a service like this can link it to an email address or phone number you never gave that business. You may first notice it as a cold message that knows your job title, or as a profile page with your name on it.

How to get a profile removed

SignalHire has a Profile Opt-Out page. It says that to have your profile removed from its site you can complete the online form there, or email support@signalhire.com, and that it aims to process requests promptly. The page also links a Do Not Sell My Personal Information option.

SignalHire vs. a people-search site

People-search sites are mostly aimed at the public looking up neighbors and relatives. SignalHire is aimed at professional outreach, but both rest on the same idea: personal details collected from public sources and sold on. Opting out of one does not remove you from the other.

How to protect yourself

  1. 1

    Use the official opt-out

    Go to the Profile Opt-Out page on signalhire.com and complete the form, or email support@signalhire.com. Type the web address yourself rather than following links in messages.

  2. 2

    Keep the confirmation

    Save any confirmation or reply you get, so you can follow up if your profile appears again.

  3. 3

    Check your public profiles

    Review what your professional profiles show publicly, such as work email and phone number, and remove what you don't want found.

  4. 4

    Look beyond one site

    Similar services keep their own copies of your details. Serus finds the sites that hold your data and removes the listings it can, so you don't repeat this on each one.

Frequently asked

Is SignalHire legitimate?

It is a real company that runs a published opt-out process. That says nothing about whether you want to be listed. Use the opt-out if you don't.

How do I delete my SignalHire profile?
