In this guide, we’ll share 14 proven ways to find email by phone and build a reliable, verified contact list.

Why Finding Email Addresses by Phone Number Matters

Streamlined Communication

Email provides a written record of conversations and allows for detailed information sharing that phone calls can’t match. When you have a phone number but need the associated email address, you can often locate the email addresses you need to contact prospects.

Enhanced Marketing Efficiency

For B2B teams, having access to both contact methods enables multi-channel campaigns with higher engagement rates. Phone numbers can be easier to find than email addresses, which makes email finding via phone numbers an efficient prospecting strategy.

Better Lead Quality

Verified email addresses paired with phone numbers indicate higher-quality leads who are more likely to engage with your outreach efforts.

2. Use Reverse Phone Lookup Services to Find Email by Phone

There are online services dedicated to reverse phone lookups. It’s much like reverse search. You can simply enter the phone number, and the service tries to search email by phone. It’s a straightforward method that has proven effective for many. Reverse phone lookup tools and directories can be a lifesaver when you have a phone number but need the associated email address.

Popular reverse lookup services:

2. Click the “Phone” tab

3. Enter the phone number and click “Phone Number Search”

4. You’ll get the results like the following

5. Lastly, check the information again and copy the info from the matching profile.

3. Try Google for Email Discovery

If you’re stuck with how to know my email ID by phone number, you can use Google to email addresses and phone numbers directly (if luck favors you).

Here’s how to approach it:

Type the phone number into Google’s search bar and hit the search button. The idea here is that if the phone number has ever been posted online, there might also be an email address associated with a phone number listed with it.

Using Google search operators can really help you narrow down your search for someone’s contact information. They’re simple to use. Just type one of these operators into Google:

[name] + email (or) email address
[name] + contact (or) contact information (or) contact me
[name] + “home town”
[name] + “company they work for”
[name] + LinkedIn
[name] + Swordfish AI
[name] + email
[name] + contact

If you have more details about the person you’re looking for, like their workplace, you can get even more specific.

Try these:

site:companywebsite.com + [name] + email
site:companywebsite.com + [name] + contact
site:companywebsite.com + firstname.lastname [at] companyname.com
site:companywebsite.com + firstnamelastname [at] companyname.com
site:companywebsite.com + firstname [at] companyname.com
site:companywebsite.com + firstname_lastname [at] companyname.com

Just replace “[name]” with the person’s name and “companywebsite.com” with the actual company’s website to start your search.

Be prepared to put in some effort. The search result for someone’s email address on Google could take you to different websites where the phone number appears, and you might find an email address mentioned there, too.

Though it’s one of the most effective ways to find email, this simple method to find email addresses using phone numbers requires patience. You’ll need to go through the search results carefully. Being thorough and detail-oriented will help as you sift through the information Google pulls up.

Important: Always verify guessed email addresses using tools like Hunter.io or EmailChecker to avoid sending to invalid addresses.

Advanced Google Search

Visit google advanced search for a range of search tools designed for finding email addresses and contact. You have the option to enter specific criteria like “match this exact phrase,” “include all these words,” “include any of these words,” and “search within a number range.”

Adjust these settings according to your needs for a more targeted email search by phone number.

To make your search results even more precise, you can select from straightforward options for “region,” “language,” “file type,” and others from easy-to-use drop-down lists. These settings allow you to home in on exactly what you are searching for, ensuring your results are as relevant as possible.

4. Check Company Websites and Directories for Email Information

If you’re looking for how to find accounts linked to phone numbers for free, checking out the business’s official website could be very helpful. Many companies list their team members’ contact details, including email addresses, to make it easier for people to get in touch.

Strategy:

1. Visit the company’s website

2. Navigate to “Team,” “Staff,” or “About Us” sections

3. Look for employee directories or contact pages

4. Cross-reference phone numbers with listed email addresses

This method involves a bit of detective work as you’ll need to carefully go through the information provided to locate the specific email address you’re after. 

Not only does this strategy help you find email addresses you need, but it also gives you a better understanding of the company’s structure and the key people within it.

5. Explore Social Media Platforms

When wondering how to check email addresses by phone number, social media platforms are integral to our lives. Many people link their phone numbers to LinkedIn, Facebook, or Twitter profiles. By searching the phone number on these platforms, there’s a chance you’ll find the linked email address.

Finding Email Addresses Using Facebook

Here’s how you can use Facebook search to get email ID from phone number–

Step 1: Utilize the Search Bar

Type the person’s name or phone number into Facebook’s search bar. If the phone number is linked to a profile, it should appear in the search results. Remember, the effectiveness of this method depends on the privacy settings of the user’s account and whether they’ve linked their phone number.

Step 2: Explore the Profile

Once you find the profile, take a moment to explore it. Some users include their email address in the “About” section, especially if the profile is used for professional purposes or networking.

Step 3: Messenger as a Last Resort

If the email address isn’t publicly listed, consider sending a polite message through Facebook Messenger. Briefly explain why you’re reaching out and ask if they’re willing to share their email address for further communication.

Twitter as Email ID Finder By Number

Using Twitter, you can easily find email linked to phone number:

Step 1: Search by Phone Number or Username

Twitter doesn’t directly allow you to search for users by phone number, so you’ll need to start with the username or real name of the individual. If you have their phone number, external tools or a quick Google search with the number might reveal their Twitter handle.

Step 2: Review the Bio

Many Twitter, now X users, include their contact information, including email address in the bio. This is especially true for professionals or businesses looking to connect with clients or collaborators.

Step 3: Engage with Direct Messages

If the email isn’t in their bio, consider reaching out via direct message. Keep your message respectful and to the point, explaining why you’re asking for their email. Not everyone checks or responds to messages from non-followers, so this method may not always yield results.

Using LinkedIn to Find Email Addresses

Here’s how to know email address on LinkedIn by phone number:

Step 1: Use LinkedIn’s Search Function

Enter the person’s name in LinkedIn’s search bar. If you have a mutual connection, you’re more likely to gain access to their full profile, which may include contact information.

Step 2: Check the Contact Info Section

On a user’s profile, look for the “Contact info” section, typically found under their profile introduction. Users often list their professional email address here for networking purposes.

Step 3: Send a Connection Request or InMail

If the email address isn’t listed or you can’t access their full profile, consider sending a connection request with a personalized note explaining your reason for connecting. Alternatively, if you have a Premium account, you can use InMail to directly message them. That’s how to find email addresses from phone numbers on LinkedIn.

6. Experimenting with Email Combinations

When you know the name of the person you’re trying to reach, guessing their email address can sometimes pay off.

Common formats include variations like: first.last@email.com, initiallastname@email.com or even firstname@email.com .

Don’t forget to try other combinations that might be used, such as: first_last@email.com  or first-initial.last-name@email.com . 

If you’re reaching out for professional reasons, keep your message respectful and concise, explaining who you are and why you’re contacting them. 

Using email verification tools can also help you avoid sending messages to non-existent addresses, saving you time and effort in your search.

 

7. Search Alternative Search Engines

When Google doesn’t give you the results you need, trying other search engines like Bing, DuckDuckGo, and Yahoo might help. Each of these has its own way of finding and showing information, that Google might not catch.

• Bing offers a rewards program and is great for image searches, which could be useful if you’re looking for visual content. 
• DuckDuckGo is all about keeping your searches private and doesn’t track you, making it a good choice for searches you want to keep confidential. 
• Yahoo, one of the oldest search engines, uses its unique ranking systems to deliver different results from what you might find on Google.

To get the most out of your searches on these platforms, try using search operators like quotes for exact matches or a plus sign to ensure certain words are included, just like you would on Google.

Each search engine’s special features and approach to privacy might make one a better fit for your search needs, so it’s worth trying each to see which one works best for you.

8. Using WhitePages for Email Discovery

WhitePages is a reliable source for looking up contact information, such as valid email addresses, using phone numbers. It gathers information from public records, which makes it useful for both personal and professional searches. 

If you have a phone number and want to find the connected email, WhitePages can offer a detailed background check that usually includes contact details.

Using WhitePages is easy: just type the phone number into the search bar and check the results for any email addresses. However, keep in mind that email with more detailed information might need a subscription or a one-time fee.

For those who need to do these kinds of searches often, getting a subscription could be a good investment, as it provides deeper data and insights.

Always remember to follow privacy laws and use the information you find on WhitePages responsibly.

Other Professional directories can be used like:

• Yellow Pages
• Better Business Bureau listings
• Industry-specific directories
• Chamber of Commerce member lists

9. Call Directly and Ask for Information

When your email lookup by phone number isn’t working, the most direct approach is often the best: pick up the phone and call. Whether you are calling the individual’s direct line or the company’s main number, a polite and professional request can yield results.

If you reach the person directly, be clear about who you are and why you’re calling. A simple explanation can often lead them to share their email address.

If you reach a receptionist or administrative staff, they can be an incredibly valuable resource. These team members have access to employee directories and can often direct your inquiry.

Effective Approach:

• Be Polite and Professional: Start by introducing yourself clearly.
• State Your Purpose: Briefly explain why you need their contact details. This is especially important when preparing to send a cold email to a potential client. A good line is, “I have some detailed information to send regarding [Topic] that’s best shared in writing.”
• Ask for Help: Instead of demanding an email, ask for the best way to contact the person. A good line is, “Could you please direct me to the best email address for [Person’s Name]?”

Keep in mind that some company policies may prevent staff from sharing email addresses directly. However, they can often forward your message to the right person, which achieves the same goal. Building a good rapport with these key contacts is a crucial networking skill.

10. Email Permutation

Trying out email permutation is one of the methods to find an email address when you have some information about your contact. 

By entering details like a person’s name into an email permutator tool, you can come up with various possible email combinations. 

This method relies on common email formats used by people and companies, giving you a list of potential addresses, including possibly the one you’re looking for.

However, remember that this method of locating an email address isn’t always accurate. The email addresses you get might not all work or be right, so you’ll need to figure out which one is a valid email. This might mean sending test emails or using tools to verify if the emails are real.

11. Utilize WHOIS Database Lookups

Conducting a WHOIS lookup is a strategic approach when you’re on the hunt for the email address of someone who owns a website, such as an independent business owner, entrepreneur, or writer. 

WHOIS databases store the registration details of domain names, including the contact information of the domain owners. This public record can be a goldmine for finding email addresses, as domain registration often requires providing a contact email.

Process:

• Visit who.is or similar WHOIS lookup services
• Enter the company domain
• Review registration contact information

Other reputable WHOIS lookup services are available, including Namecheap, DomainTools, Nominet, and DMCA’s free WHOIS tool. The specific tool you choose is less important than accessing the WHOIS database itself.

Keep in mind, though, that while WHOIS data is meant to be publicly accessible, domain owners have the option to privatize their contact information. This means that in some cases, the email address you’re seeking may not be visible.

12. Use CRM and Sales Intelligence Platforms

Apollo offers a free forever plan with 40 credits per month and gives you both personal and work emails, real-time email verification.

Other platforms to consider:

• Apollo.io: 210M+ contact database
• ZoomInfo: Enterprise-grade contact intelligence
• Lusha: LinkedIn-focused prospecting
• Hunter.io: Domain-based email discovery

13. Check Professional Networks and Forums

Industry-specific forums, professional associations, and networking sites often contain member directories with contact information.

14. Employ OSINT (Open-Source Intelligence) Techniques

Before we can link a phone number to an email, it’s often easier to start by connecting an email to a LinkedIn profile.

Advanced OSINT methods include:

• Cross-referencing multiple data sources
• Social media account correlation
• Public records research
• Historical data analysis

Why You Should Find Email by Phone?

Well, sometimes you have a phone number but need to send detailed info or documents. Finding mobile numbers to email ID search can make communication smoother and more efficient. But there’s more to this.

Efficiency in Communication

You’re speeding up your outreach when you find an email through a phone number. Many professionals today lean towards email for more detailed and lengthy discussions. 

Unlike a quick phone call, an email provides a written conversation record. This ensures that both parties understand what was discussed. Thus, it reduces the chances of miscommunication.

Smooth Marketing

For businesses, having access to both phone numbers and email addresses can be a game-changer. It lets them run their marketing campaigns more effectively.

By sending personalized emails, businesses often see higher engagement rates. Moreover, combining phone and email data can refine your target audience segmentation. It ensures that your marketing efforts hit the mark.

Improved Customer Service

Every customer problem is different, and solving these problems can sometimes mean using more than one way to communicate. 

Email is convenient for sending documents, pictures, or detailed instructions. Customers also like being able to pick how they want to get in touch, whether it’s by a phone call or email.

Building Trust

Transparent and open communication is the foundation of building trust. When businesses or individuals share both their phone and email details, it signals a willingness to connect and engage. 

Over time, this trust can lead to long-term professional relationships and collaborations

Data Enrichment

Having a database with lots of contact details is like a treasure for businesses. With richer data at their disposal, companies can make more informed decisions. 

This well-maintained database, along with contact-finding tools, becomes an invaluable asset for future planning and strategizing.

Networking Opportunities

In the professional world, networking is key. With multiple contact details, professionals can expand their network exponentially.

An email introduction can often lead to more in-depth phone conversations, opening doors to new opportunities and collaborations.

Ease of Automation

In today’s digital world, automation is a big win. Systems that can automatically link phone numbers with email addresses make managing databases a breeze.

This reduces manual effort and minimizes potential errors, ensuring that the database remains accurate and up to date.

Feedback Collection

Feedback is crucial for growth. Email is a preferred channel for sending out surveys and customer feedback forms. It allows customers to respond at a time that’s convenient for them. By collecting and acting on this modern feedback system, businesses can continually improve and adapt to their customers’ needs.

Cost-Effective

Lastly, let’s talk about money. Email communication, especially in bulk, can be much more cost-effective than long phone calls. In the long run, these cost savings contribute significantly to a company’s overall profitability.

How to Remember the Essentials to Find Email by Phone?

Finding an email using a phone number can be a valuable tool. But it comes with its set of responsibilities. Remembering these points, you ensure that your actions are respectful, accurate, and ethical.

Stay Within Legal Limits

Your top priority is to collect B2B contacts ethically. Using publicly available resources like online directories is a smart move. Plus, avoid accessing restricted databases, especially those belonging to cell phone providers.

Remember, various laws globally, including the GDPR and CAN-SPAM, dictate how you can reach out to others. Your emails need to offer a straightforward opt-out option, present clear information about you, and justify your reason for contacting the person.

Accuracy Matters

Accuracy is key when you’re on the hunt for an email address. Before searching, make sure you have the correct phone number. Using incorrect or outdated information can lead to miscommunication, errors, or even reaching out to the wrong person.

It’s always a good practice to double-check the details you have. This step can save you from potential embarrassment and ensure that your efforts are directed correctly.

Use Reliable Sources

The internet is huge and full of information, but not everything you find is reliable. When you’re trying to find an email address from a phone number, make sure to use trusted platforms or services. 

You might come across websites that promise fast results, but if something seems too good to be true, it often is. Using reputable sources not only makes sure the information you get is accurate but also helps keep your data safe.

Treat Personal Information with Respect

Securing email addresses is just the beginning. You also need to manage this information responsibly. That means —

• Integrating your Customer Relationship Management (CRM) tool with your data solutions. It keeps your marketing and sales teams aligned, using one system to manage data effectively.
• Committing not to share or sell the personal information you collect. Your use of this data should strictly support your business goals.
• Ensuring data cleanliness by eliminating duplicate entries, updating with new data, and completing any missing details.
