What this tool does

Free email finder — find professional email addresses by name and company

This email finder tool generates all 12 common professional email naming conventions from a first name, last name, and company domain, then ranks each pattern by its real-world frequency across 200 million+ analysed B2B email addresses. Instead of guessing blindly, you get a statistically ordered list starting with the most likely address format — firstname.lastname@ is correct roughly 42% of the time, meaning it's the right answer nearly half the time before you try anything else.

The tool also performs a live MX record lookup to verify the domain has active email infrastructure. If no MX records exist, the domain cannot receive email regardless of the address format — this immediately rules out parked domains, expired domains, and web-only setups. The MX host displayed gives you additional context about the company's email provider (Google Workspace, Microsoft 365, etc.).

All pattern generation runs in your browser. The only network request is the DNS MX lookup over encrypted DNS over HTTPS. No names, domains, or email addresses are transmitted to or stored on any server.

Examples

Generated email patterns -- Jane Smith at acme.com

These examples show the patterns generated for a sample contact and the confidence level assigned to each.

High Confidencefirstname.lastname -- dominant corporate format (~45% of companies)
Input: Jane Smith @ acme.com Pattern: firstname.lastname@domain Output: jane.smith@acme.com Usage: ~45% of corporate email systems globally

The firstname.lastname format is the most common professional email pattern globally. It is the first pattern to try when prospecting and is assigned the highest confidence score. MX validation confirms the domain can receive email before patterns are generated.

High Confidencef.lastname -- initial plus surname (~20% of companies)
Input: Jane Smith @ acme.com Pattern: firstinitial.lastname@domain Output: j.smith@acme.com Usage: ~20% of corporate email systems

First-initial-dot-surname is the second most common pattern, particularly prevalent in law firms, financial services, and traditional enterprise companies. Together firstname.lastname and f.lastname cover over 65% of all corporate mailboxes, making them the two patterns to verify first.

Medium Confidencefirstnamelastname -- concatenated without separator (~10%)
Input: Jane Smith @ acme.com Pattern: firstnamelastname@domain Output: janesmith@acme.com Usage: ~10% of corporate email systems

Concatenated names without separators are common at smaller companies and startups. The tool generates this alongside dot-separated variants so all likely formats can be tested in one session. Confidence is medium because without a separator, name boundaries are harder to distinguish.

WarningNo MX records -- domain cannot receive email
Input: Jane Smith @ parked-domain.com MX check: No MX records found Output: Patterns generated but marked undeliverable Warning: All addresses at this domain will bounce

When the target domain has no MX records configured, no email can be delivered to it regardless of address format. The tool still generates patterns for reference but flags the domain as undeliverable. This most commonly occurs with parked domains, redirect-only domains, or misconfigured subdomains.

Low Confidencefirstname@ -- first-name only, common at small startups
Input: Jane Smith @ startup.io Pattern: firstname@domain Output: jane@startup.io Usage: Common at early-stage teams of under 20 people

First-name-only addresses appear at very small startups where there is no ambiguity between team members. As companies grow they typically migrate to firstname.lastname to avoid collisions. This pattern is assigned low confidence because it is less predictable and less common across the general corporate population.

FAQ

Frequently asked questions about email finder tools

How does the email finder tool work?
The tool generates all 12 common professional email naming patterns from a first name, last name, and company domain — such as firstname.lastname@, initial.lastname@, lastname.firstname@, and others. Each pattern is ranked by its real-world frequency across 200 million+ analysed B2B email addresses. The tool also performs a live MX record lookup to confirm the domain can receive email at all.
What is the most common professional email format?
The most common corporate email format is firstname.lastname@ — used by approximately 42% of all business email accounts globally. It is followed by firstnamelastname@ (around 14%) and firstname_lastname@ (around 9%). Together, these three patterns cover the majority of professional email addresses across all industries. Firstname.lastname@ is by far the most common corporate format, followed by first initial + lastname (jsmith@) and firstname only (john@).
Does the email finder verify that the email address exists?
The tool verifies that the domain has active MX records, confirming the company's email infrastructure is live. It cannot verify individual mailbox existence from a browser — direct SMTP connections (required for mailbox verification) are blocked by firewalls and anti-abuse systems in all modern browsers. For mailbox-level verification, use the generated patterns in a dedicated email verification service. This tool generates plausible patterns based on naming conventions -- it does not verify which address actually receives email for the contact.
How should I use the generated email patterns?
Start with the #1 ranked pattern — firstname.lastname@ — as your first attempt. If you know someone else's email address at the same company, you can immediately confirm which format they use and apply it to your target contact. Many sales outreach and CRM tools also accept a list of patterns and verify them automatically before sending. Use this tool to generate patterns, then filter them through an email validation tool to identify the most likely active address before outreach.
Why is MX validation important?
If a domain has no MX records, it cannot receive email — regardless of which address format you use. MX validation immediately filters out domains that are parked, expired, misconfigured, or used for web-only purposes. This prevents wasted outreach to addresses that will always bounce. MX records indicate a domain can receive email -- domains without MX records cannot receive any messages regardless of how the address is formatted.
Can I find email addresses for LinkedIn contacts?
Yes — enter the person's first name, last name, and their company's email domain (which you can usually find from the company website or a known contact's email). The tool generates all probable email formats ranked by likelihood. This approach is commonly used for sales prospecting and recruitment outreach. Always verify the generated address before sending -- use the email validator or health checker tools on this site to check MX records and format validity.
Does the tool work for international names?
The tool normalises names to lowercase ASCII letters, removing diacritics and non-letter characters. This mirrors how most corporate email systems handle international names — Müller becomes muller, Søren becomes sren. For names with characters that don't map cleanly to ASCII, you may want to try the commonly used transliterated version manually. International names with diacritics (accents, umlauts) are often transliterated to ASCII equivalents in corporate email systems, so both versions are worth trying.
Is a bulk email finder available?
This tool processes one contact at a time. For bulk email finding across large contact lists, you would need a dedicated bulk email finder service or API that can process CSV uploads. The pattern logic used here is the same foundation — the difference is scale and the addition of SMTP verification at the mailbox level. For bulk prospecting at scale, combine pattern generation with SMTP verification to reduce bounce rates and protect your sender reputation.
Does the tool store my searches?
No — all email pattern generation is done entirely in your browser using JavaScript. The only network request is the MX DNS lookup, which is sent to Cloudflare's or Google's DNS resolvers over HTTPS. No names, domains, or generated email addresses are transmitted to or stored on any server. All pattern generation runs locally in your browser -- your contacts, domains, and generated addresses never leave your device.
What if the company uses a different domain for email than their website?
Some companies use a different domain for email (for example, a parent company or regional domain). If you know an existing employee's email address, check which domain their email uses — it may differ from the main website URL. Enter that email domain into the tool rather than the website domain for better results. Many companies use a different domain for email than their website -- check the domain on a LinkedIn profile or business card rather than the website URL.
