Follow the sections in order if you are new, or jump to any feature using the links above.

How SignalHire Works

At its core, SignalHire matches a person to verified contact details in real time.

You start with a name, a LinkedIn profile, a company website, or a search filter.

SignalHire checks that person against its database of over 850 million contacts.

When it finds a match, it reveals personal and 商业 emails plus mobile phone numbers.

Each contact is verified live, so the email addresses and phone numbers you get are current.

From there, you can save the right contact to a list, send it to your 客户关系管理, or start an email sequence.

Every reveal costs one credit, and the free plan refills 10 free credits monthly so you can test the process.

Getting Started with SignalHire

使用任何功能之前，请先完成此一次性设置。

It takes about 3 minutes and the free plan is enough to begin.

You only do this once, and then every feature below works right away.

步骤 3：完成初始设置

How to Use SignalHire Database

数据库 lets you search a database of over 850 million profiles for contact discovery.

The database is the heart of SignalHire and the first place most users start. It holds detailed information on people, companies, and roles, so you can find the right contact for any sales or recruiting list. Every record is checked in real time, which keeps the contact data fresh and accurate. Many users treat it as their main search hub for finding contacts at any company.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Open the Search Tab

Open the search tab inside SignalHire and pick a filter set.

You can search by company name, job title, location, industry, or skills. SignalHire supports advanced search filters for candidates based on skills and experience, which helps recruiters and sales teams narrow a big list fast.

Step 2: Build Your Query

Add company name, job title, location, and skills to narrow the search.

SignalHire’s AI-driven search generates targeted candidate queries straight from a job description, so talent acquisition teams can paste a role and get matching people in seconds.

Each result shows detailed information about that person, company, and page source in real time, with a verification badge next to every contact.

这就是它的样子：

✓ 检查点： Verified email addresses and mobile phone numbers appear next to each profile.

Step 3: Reveal the Right Contact

Click any person to reveal personal and business emails plus phone numbers.

Each reveal uses one credit and returns verified contact details, including personal emails, business emails, and mobile phone numbers for that person.

Sales teams use the database to build outbound lists, while recruiters use it for talent acquisition across roles. Because it draws on over 200 million candidate profiles and 850M+ contacts overall, you rarely run out of people to reach for lead generation. Over time, a saved search becomes a steady stream of fresh decision makers to reach.

Because the database refreshes its contact data, the same search can surface new people over time. That makes it a reliable engine for ongoing lead generation, not just a one-time list pull. Recruiters especially value the depth across professionals and industries.

How to Use SignalHire Browser Extension

浏览器扩展 lets you find emails and phone numbers in 3 seconds while you browse LinkedIn.

The browser extension is the fastest way to use SignalHire day to day. This free extension turns any profile page into a contact finder, so you never copy and paste names into a separate search. It is a true linkedin email finder that also works far beyond LinkedIn. It is the feature people point to when they explain why SignalHire feels so fast.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Open a Profile

Open a LinkedIn, Facebook, or GitHub profile in your browser.

The chrome extension reads the page and matches the person to its database. It works on LinkedIn, Facebook, and GitHub, so your contact discovery is not locked to one platform.

Step 2: Click the Extension

Click the free extension icon to start contact discovery on that person.

The extension finds emails in 3 seconds and can even find email addresses using phone numbers when an email is hidden.

This linkedin email finder works on LinkedIn, Facebook, and GitHub, and the extension finds emails in 3 seconds.

这就是它的样子：

✓ 检查点： You see verified business emails and personal emails with a green accuracy badge.

Step 3: Copy the Contact Info

Copy the professional email addresses and mobile phone numbers it returns.

Real-time verification ensures 95% email accuracy with the extension, so you can trust the contact info before you reach out.

Sales professionals keep the extension pinned while prospecting on LinkedIn Sales Navigator, and recruiters use it to find emails on GitHub. The free extension gives 10 free credits monthly, which is enough for light users to test the tool through free trials before moving to paid plans. Once it is pinned, finding contact info becomes a single click in your daily routine.

The free extension is what most users open first each day. It removes the gap between spotting a person and getting their contact info, so your search-to-outreach time drops to seconds. For sales professionals who live on LinkedIn, this alone is worth the install.

How to Use SignalHire API

API lets you push contact data into your own apps with api access.

The API is for teams that want to build contact discovery into their own tools and services. Api access lets developers pull verified contact data on demand, so you can power automated workflows without anyone clicking a button. It is the backbone of large-scale contact enrichment. For developers, it is the cleanest way to wire contact data into existing services.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Open API Settings

Open the API settings page and generate your secret key.

Keep the key private, since it controls access to your account and credits.

步骤 2：连接您的应用

Paste the key into your tool to connect SignalHire to automated workflows.

SignalHire’s API enables custom integrations for unique workflows, so you can connect it to a CRM, a data warehouse, or an internal app.

SignalHire’s API enables custom integrations for unique workflows and one-click export to major CRMs.

这就是它的样子：

✓ 检查点： Your app receives verified contact data in real time without manual data entry.

Step 3: Request Contacts

Send a request to pull personal and business emails into your database.

Each request returns verified contact information in real time, and you can export contacts to your CRM without creating duplicates.

Marketing and sales teams use the API to keep their CRM platforms full of fresh contact data. Because it runs contact enrichment on a schedule, your records stay current without manual data entry, which saves the support team and reps hours each week. Engineering teams set it up once and then forget it, since it runs on its own.

Teams that send contact data between several tools rely on the API to keep everything in sync. It turns SignalHire into a quiet background service that feeds verified emails and phone numbers into your stack, so reps always work from fresh records.

How to Use SignalHire Lead Tracker

线索追踪器 lets you organize every right contact and follow up at the right date.

The lead tracker keeps your pipeline tidy once you start finding contacts at scale. It stores detailed information on each person and company in one place, so nothing slips through. This is where lead generation turns from a pile of emails into an organized process. Think of it as a light CRM that lives right where you find your contacts.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Create a List

Create a list and name it by campaign, company, or persona.

Clear list names make it easy to find the right contact later, especially when you run many campaigns at once.

Step 2: Add Contacts

Add contacts from any search so each lead lands in one place.

You can move contacts between lists or tag them by stage, which keeps your data clean and easy to filter.

The lead tracker keeps detailed information on each person so sales teams never lose a thread.

这就是它的样子：

✓ 检查点： Each list shows status, owner, and the last contact date.

Step 3: Track Status

Track replies, opens, and next steps for every contact.

Each entry shows the last contact date and the owner, so sales teams always know who reached out and when.

Recruiters track candidates from first contact to interview, while sales reps track prospects from 冷邮件 to demo. The tracker connects to your CRM integration, so the right contact and their details stay in sync across both tools. A tidy tracker means your team always knows the next move for every contact.

Good tracking is the difference between a busy pipeline and a productive one. By keeping every contact, date, and status in one view, the tracker helps sales teams follow up on time and never let a warm lead go cold.

How to Use SignalHire Email Sequences

电子邮件序列 lets you send personalized email outreach on autopilot.

Email sequences turn SignalHire from a contact finder into an outreach engine. You write once, then the tool sends personalized emails to many people on a schedule. This pairs perfectly with verified business emails, since clean data keeps your sender reputation strong. Outreach and contact discovery sit in one place, so you never juggle separate tools.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Write Your Sequence

Write a short sequence and add merge fields like company name and person.

Personalization tokens pull each contact’s details automatically, so every email feels written by hand.

步骤二：设定时间表

Set send days and delays so emails go out at the right time.

Spacing your sends protects deliverability and keeps your outreach from looking like bulk spam.

SignalHire’s platform supports email outreach 自动化 with personalization and tracks opens and replies live.

这就是它的样子：

✓ 检查点： You see live open and reply rates for every step of the sequence.

Step 3: Launch and Watch

Launch the campaign and watch opens and replies in real time.

SignalHire allows tracking of email opens and replies in real time during outreach campaigns, so you know which message lands.

Sales professionals run multi-step sequences to warm cold prospects, and recruiters use them to reach passive candidates. Because SignalHire verifies email addresses before sending, deliverability stays near 94%, which means more replies from the right contact. The live open and reply data tells you which message to double down on.

Sequences scale your outreach without losing the personal touch. Each email still names the person and company, so prospects feel addressed directly even though the process runs on automated workflows behind the scenes.

How to Use SignalHire Bulk Search

Bulk Search lets you find emails in bulk for up to 1000 people at once.

Bulk search is built for teams that need contact data at scale. Instead of revealing people one by one, you upload a whole list and let SignalHire enrich every row. This saves hours and is the fastest path to a full contact database. It is the feature that turns SignalHire from a lookup tool into a list-building machine.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Upload Your List

Upload a CSV list of names, companies, or LinkedIn URLs.

SignalHire allows you to upload bulk lists of candidates for automated contact verification, so messy lists become clean ones.

Step 2: Run Bulk Discovery

Run bulk contact discovery to enrich every row at once.

The tool can enrich CSV files with missing candidate contact information, filling gaps in emails and phone numbers.

SignalHire lets you upload bulk lists of candidates for automated contact verification and can enrich CSV files with missing contact information.

这就是它的样子：

✓ 检查点： Each row now shows verified personal and business emails and mobile phone numbers.

步骤 3：导出结果

Use CSV export to download verified emails and phone numbers.

You can find emails in bulk for up to 1000 people at a time, then download the finished file.

Marketing teams enrich event lists before a campaign, and recruiters enrich sourcing exports before outreach. The CSV export drops straight into your CRM platforms, so the data flows into your process with no manual entry. A whole prospect list goes from raw names to verified contacts in a single run.

For anyone who works with lists, bulk search is the biggest time-saver in the tool. A spreadsheet that would take hours to enrich by hand becomes a finished, verified file in minutes, ready for your CRM platforms.

How to Use SignalHire Social Media Lookup

社交媒体 Lookup lets you find contact info from social media profiles.

Social media lookup widens your reach beyond LinkedIn. SignalHire supports multi-channel sourcing from platforms like LinkedIn and GitHub, plus Facebook and other websites. This means you can match a person on any social profile to verified contact data. For hard-to-reach people, this is often the search that finally surfaces a real email.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Open a Social Profile

Open a profile on LinkedIn, Facebook, or other websites.

The tool reads public profile signals to match the person to its database.

Step 2: Run the Lookup

Run the lookup to match that person to verified contact data.

Multi-channel sourcing pulls contact info from platforms like LinkedIn and GitHub, so you are not limited to one network.

Multi-channel sourcing pulls contact info from platforms like LinkedIn and GitHub, plus Facebook and other social media.

这就是它的样子：

✓ 检查点： You get matched email addresses and phone numbers for the social profile.

步骤 3：保存联系人

Save the right contact into a list or your CRM.

Each saved record keeps the source page, so you always know where the contact came from.

Recruiters source developers on GitHub, and sales teams find founders on Facebook and other social media. Pairing this with LinkedIn Sales Navigator lets you reach decision makers that other tools and services miss. This is how teams reach niche talent and founders who skip the usual networks.

Not every prospect lives on LinkedIn, and this feature meets them where they are. By pulling contact info from Facebook, GitHub, and other websites, it widens your reach to people other tools and services cannot match.

How to Use SignalHire Phone Number Search

Phone Number Search lets you reveal mobile phone numbers for the right contact.

Phone number search is what sets SignalHire apart from many email-only tools. It reveals verified mobile phone numbers so you can call decision makers directly. For sales professionals, a phone line often beats another email in a crowded inbox. In crowded markets, a verified number is the shortcut to a live conversation.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Find a Person

Find a person in the database or on a company website.

You can start from a search result, a saved list, or a live profile in your browser.

Step 2: Reveal the Number

Click reveal to show verified mobile phone numbers.

SignalHire can find phone numbers alongside emails, and real-time verification keeps the contact data accurate.

SignalHire can find phone numbers alongside emails, and real-time verification keeps the contact data accurate.

这就是它的样子：

✓ 检查点： A verified mobile number appears next to the email addresses.

Step 3: Save or Call

Save the number to a list or call right away.

Saved numbers sync to your CRM, so the whole sales team can see them.

Account executives use phone search to book meetings faster, and recruiters use it to reach passive candidates who ignore email. Because the numbers are phone-verified, you waste fewer dials on dead lines and reach the right person sooner. A short call often moves a deal further than a week of unanswered emails.

A direct phone line changes the math on outreach. When email inboxes are crowded, a verified mobile number lets sales professionals start a real conversation, which often books meetings faster than any sequence.

How to Use SignalHire Website Contact Extractor

Website Contact Extractor lets you pull email addresses straight from any company website.

The website contact extractor finds contact details right from a company website. Instead of hunting through pages, you let the extension scan the domain for you. This is a quick way to find the right contact at a target account. It is a fast way to research an account before any sales call.

以下是使用步骤。

现在让我们逐一分析每个步骤。

Step 1: Visit a Company Website

Visit any company website or domain you want to reach.

Open the homepage, team page, or contact page where details usually appear.

Step 2: Run the Extractor

Run the extractor to scan the page for contact details.

The extension can extract emails from company websites automatically, pulling business emails from the domain.

The extension can extract emails from company websites automatically, with real-time email verification ensuring 95% email accuracy.

这就是它的样子：

Step 3: Collect the Emails

Collect verified business emails and add them to a list.

Real-time email verification ensures 95% email accuracy, so the addresses you collect are ready to use.

Sales teams use the extractor to map every contact at a target company, and agencies use it to build prospect lists from a client’s competitors. Combine it with bulk search to turn a whole domain into a verified contact list in one process. It pairs well with account-based plays where you target a short list of companies.

Account-based teams love this feature because it maps a target company quickly. Point it at a company website and it surfaces the business emails you need, turning a single domain into a list of the right contact people.

SignalHire Pro Tips and Shortcuts

After testing SignalHire for over eight months, here are my best tips for faster contact discovery.

These small habits save credits, protect your data, and help you reach the right contact sooner.

键盘快捷键

行动	捷径

大多数人错过的隐藏功能

• Free credits reset: The free plan refills 10 free credits monthly, perfect for light users and free trials of paid plans.
• CRM integration: One-click export sends contacts to Salesforce, HubSpot, and Zoho without duplicates.
• Find emails from phone numbers: The email finder can find emails using phone numbers when an address is hidden.
• Saved searches: Save a filter set once, then rerun it later to find fresh contacts in seconds.

Tips to Save Credits

Credits are the currency of SignalHire, so spend them on the right contact only.

Filter by company name, title, and location before you reveal anyone, so you never waste a credit on a bad match.

Use bulk search for large lists, since it is faster than revealing contacts one by one.

Turn on real time email verification so you never pay for an address that bounces.

SignalHire Common Mistakes to Avoid

These are the mistakes I see new users make most often with this email finder.

Avoid them and you will save credits, protect your sender reputation, and stay on the right side of data compliance.

Mistake #1: Skipping Email Verification

SignalHire verifies emails in real time using third-party tools, so turning it on keeps your bounce rate near 3 to 5 percent.

Mistake #2: Wasting Credits on Bad Searches

Good filters mean you spend credits on decision makers, not on people who will never reply.

Mistake #3: Ignoring Data Compliance

SignalHire is built with data compliance in mind, but you still need to honor a removal request when a person asks.

Mistake #4: Treating Every Tool the Same

SignalHire shines because it covers both emails and phone numbers, so lean on the feature that fits each task.

SignalHire Troubleshooting

Most issues with this contact finder have a quick fix. Here are the ones users hit most.

Problem: The Browser Extension Shows No Emails

原因： The profile page had not fully loaded before you clicked the extension.

使固定： Refresh the page, wait two seconds, then click the chrome extension again. If it still shows nothing, sign out and back into the extension to reset your session.

Problem: A Contact Has No Phone Number

原因： Not every person in the database has a verified mobile number on file.

使固定： Try the phone number search and the website contact extractor for the same person. Checking a second social profile, such as Facebook, sometimes surfaces a number the first source missed.

Problem: You Ran Out of Credits

原因： The free plan gives 10 free credits monthly, which light users can use up fast.

使固定： Wait for the monthly reset or move to one of the paid plans for more searches. You can also save credits by filtering your search tightly before you reveal any contact info.

Problem: CRM Export Created Duplicates

原因： The CRM matching field was not set before the export ran.

使固定： Map the email field in your crm integration so the export skips existing contacts. Run a quick test with five records first to confirm the match works before you push a full list.

Problem: An Email Bounced After Sending

原因： The address changed, or verification was off when you revealed the contact.

使固定： Turn on real time email verification and re-check the contact before your next send. For older lists, run the addresses through bulk search again so any stale records get refreshed.

Problem: A Person Asked to Be Removed

原因： Their personal emails appeared in your results and they sent a removal request.

使固定： Submit the opt-out on the SignalHire page so their info is removed for data compliance. Keep a short record of the request date in case the person follows up with the support team.

📌 笔记： If none of these fix your issue, contact the SignalHire support team.

Always verify before you send. Turn on real time email verification so each address is checked live. Clean data keeps your deliverability near 94% and your domain reputation safe.

Filter before you reveal. Add company name, job title, and location to your search first. Tight filters mean you reveal decision makers, not random contacts, which saves credits for the right contact.
