Key takeaways
Six methods cover almost every case: the company website, a domain search on Google, social and professional profiles, the email format, the Google Maps listing and bulk collection from websites
Two kinds of address exist: role inboxes such as info@ and sales@ (standardised in RFC 2142) and named mailboxes for a specific person
Verification comes before sending: syntax, MX records and an SMTP check, with catch-all and disposable addresses flagged
B2B outreach has rules: GDPR recital 47 allows direct marketing as a legitimate interest, UK PECR treats sole traders like consumers, and US CAN-SPAM requires a postal address and an opt-out honored within 10 business days
Google Maps does not provide business emails, so the route is listing, then website, then published email
To find a company email address, open the company's website and read the contact page, footer, legal notice and team page. If nothing is published, search Google for the domain with the @ sign, check the business's profiles, or apply the company's email format to a named contact. Then verify the address before you send.
Definition
What is a company email address, and what is an email lookup?
A company email address is any mailbox on a business's own domain, such as info@company.com or maria.lopez@company.com. An email lookup is the process of finding that address from details you already know, such as a name, a domain or a business listing, and then confirming that the mailbox still accepts mail.
There are two kinds of company address, and the one you need decides where you look. A role inbox belongs to a function rather than a person. RFC 2142 defines the standard names info, marketing, sales and support for exactly this purpose. A named mailbox belongs to one employee and usually follows a pattern across the company.

The methods
The 6 ways to find a company email address
Work through these in order. Each one costs more effort than the previous, so stop as soon as you have a published address you can verify:
1
Read the company website first
The contact page, footer, legal notice and team page are the only places the company controls itself. Many sites also publish an address in the privacy policy or terms. Published addresses are the most reliable because the company chose to show them.
2
Search Google for the domain
Type site:company.com "@company.com" into Google. It lists pages on that site that mention an address, including PDFs, press pages and old blog posts that the navigation no longer links to.
3
Find the right person, then apply the email format
Identify a name and role on the team page or a professional profile. Most companies follow one pattern for every mailbox. Our guide to company email formats lists the common ones, and one confirmed address is enough to infer the rest.
4
Check profiles and public documents
Business profiles, directories, conference speaker pages and public registries sometimes show a contact address. Treat these as leads to confirm, since they go stale faster than the company website.
5
Go through the Google Maps listing
A Google Maps listing normally shows a name, address, phone number and website. It does not provide an email, but the website it links to usually does. This is the fastest route to local businesses such as dentists, restaurants or plumbers.
6
Collect emails in bulk when you need a list
For ten companies, manual research works. For a city or a niche, collect the listings and read their websites automatically. Our business leads database guide explains how to structure that data. If you only need a few names, compare free email finder options first.

A list of published emails, to be verified
No single source holds every address, so accuracy comes from cross-checking two or three of them and verifying the result. Which source you trust depends on what you plan to do next: a published role inbox is enough to start a conversation with a small business, while enterprise prospecting needs the named contact.
The expensive mistake is treating "found an address" as "have a contact". An unverified address is a liability: every bounce and spam complaint quietly erodes the sender reputation that decides whether your real emails land at all.
Verification
How do you check that a company email address works?
You check it in three layers without sending a message: syntax, domain and mailbox. A found address that skips these checks is only a guess, and guesses bounce. Our guide on how to verify an email address without sending goes deeper. The short version:
Syntax: the address is well formed, with one @ sign and a valid domain.
Domain (MX): the domain publishes mail exchanger records, so it can receive email at all.
Mailbox (SMTP): the receiving server accepts the specific address, without a message being delivered.
Catch-all and disposable flags: catch-all servers accept any address and hide invalid ones, so treat their results as uncertain.
Addresses decay as people change jobs and businesses close, so verify again before each new campaign.
Legality & mistakes
Is it legal to email a company address you found online?
Usually yes for B2B outreach, though the rules depend on where the recipient is, and they regulate how you use an address more than how you find it. Three frameworks cover most senders:
EU, GDPR: recital 47 of the General Data Protection Regulation says processing personal data for direct marketing may be regarded as a legitimate interest. You still need relevance, transparency and a way to object.
UK, PECR and UK GDPR: the ICO guidance on B2B marketing states that the email marketing rule does not apply to corporate subscribers, but sole traders and some partnerships are treated as individuals. The UK GDPR still applies when you know a person's name.
US, CAN-SPAM:15 U.S.C. 7704 requires clear identification that the message is an advertisement, a valid physical postal address and an opt-out honored within 10 business days.
Our GDPR guide for B2B sales teams covers the full framework. This is general information, not legal advice. In practice, five habits keep you on the safe side:
Prefer business mailboxes over personal addresses.
Make the offer relevant to the recipient's role.
Identify yourself and your company in every message.
Include a one-click opt-out and honor it immediately.
Keep a record of your lawful basis and delete data on request.
Mistake 1: skipping verification
Sending to a found-but-unverified address spikes bounces and can damage your domain. Verify every result before the first send.
Mistake 2: guessing dozens of addresses
Firing at every possible pattern creates bounces and looks like abuse. Confirm one address, then infer the format.
Mistake 3: trusting one source
A single source goes stale fast. Cross-check the website, the format and a directory before you trust an address.
Mistake 4: no opt-out record
Re-contacting someone who opted out is a compliance breach. Keep a suppression list and your lawful-basis notes from day one.
Finding a company email is not a search trick. It is find, verify and contact responsibly, in that order.
How Vonsel helps
How can you find company emails for a whole city or niche?
Search Google Maps and press Start. Vonsel gathers the business results as you explore the map, going beyond the pins you can see at a glance. Pause, continue and save your search when you are ready.
Google Maps does not provide business emails. Vonsel visits the available business websites to find published emails, additional phone numbers and links to up to 118 supported social networks and other platforms. What it finds depends on what each website publishes, so verify the result before you send.
Then keep the businesses on a map, organise them by stage, edit their details and use a Kanban board, calendar, notes, actions, tags and custom fields. If you want to see the extraction first, watch the video tutorial on the Google Maps scraper page. Plans and limits are on the pricing page.
In short:
Start from the company website, then widen the search only if you need to.
Cross-check more than one source and always verify before sending.
For scale, start from local business listings and collect the published emails in bulk instead of looking them up one by one.

Search Maps, collect published website contacts and organise your prospects in the CRM. Free extraction covers 200 businesses a month; AI and export depend on your plan.
ICO: Business-to-business marketing. Explains how PECR email rules differ for corporate subscribers and for sole traders, and that UK GDPR still applies.
Start with the company's own website: the contact page, the footer, the legal notice and the team page. If no address is published, search Google for the domain plus the @ sign, check the business's social profiles, or infer the format from one known address. Verify the result before sending, because a found address is not a working one.
What is an email lookup?
An email lookup is the process of finding the email address linked to a person or company from details you already have, such as a name, a company domain or a business listing. A complete lookup has two parts: finding a candidate address from public sources, and verifying that the mailbox exists and accepts mail.
Can I find a business email address from Google Maps?
Google Maps listings normally show a business's name, address, phone number and website, not an email. The practical route is to take the website from the listing and read its contact pages, which is what Vonsel automates: it visits the available business websites and collects the emails they publish. What it finds depends on what each site publishes.
What if the company does not publish any email address?
Try the contact form, the phone number from the listing, or a named person on the team page whose address you can infer from the company's email format. Some businesses only want to be reached by form or phone, and that is a signal worth respecting. Do not guess dozens of addresses at once, because bounces damage your sender reputation.
Is it legal to email a company address I found online?
Usually yes for B2B outreach, but rules apply. The GDPR says direct marketing may be a legitimate interest, the UK treats corporate subscribers differently from sole traders, and US CAN-SPAM requires a postal address, ad identification and an opt-out honored within 10 business days. Rules vary by country, so check yours before a campaign.
Is info@ or a named address better for cold outreach?
A role inbox such as info@ or sales@ is the safest, most often published address and works well for a first, relevant message to a small business. A named address reaches the decision-maker directly but is harder to find and is personal data in many cases. Use the role inbox to get a reply, then ask for the right person.
How do I check that a company email address works?
Run three checks: syntax, whether the domain has mail (MX) records, and an SMTP check that the mailbox accepts mail, without sending a message. Flag catch-all domains, which accept everything and hide invalid addresses, and remove disposable addresses. Verification keeps bounces low and protects the domain you send from.
Is it better to look up emails one by one or in bulk?
One by one suits a handful of named targets. For prospecting a city or a niche, start from a list of local businesses with their websites and collect the published emails in bulk, then verify before sending. It saves hours of manual searching and keeps every contact in one place for follow-up.
