Google Maps hides the email behind the business website. Here is how an email scraper gets it, how to check the list, and how to send to it legally.
An email scraper is a tool that collects the email addresses published on web pages and saves them as a list. Google Maps profiles show no email, so a Google Maps email scraper first captures the listings, then visits each business website and reads the contact details published there. Vonsel does both steps in a free Chrome extension.
Google Maps shows no emails because the listing was never designed to hold one. A profile carries a name, category, address, phone, website, hours, rating and reviews. The same is true for developers: the Places API data fields list a phone number and a website URI, and no email field at all.
The email lives one click away, on the business website. Most owners publish an address like info@ or hello@ on a contact page, an about page or the footer. A useful email scraper for Google Maps is really two steps: capture the map results, then visit every website and read what it publishes.
That is also why a generic email scraper that only reads the page you have open is a poor fit for local prospecting: it never sees the list of businesses, only one page at a time. The table compares the four ways people usually try to get emails from Maps.
| Method | Finds the list of businesses | Finds the email | Effort |
|---|---|---|---|
| Copy and paste by hand | Yes, one listing at a time | Only if you open each website and find it | An afternoon per hundred businesses |
| Generic email extractor on a page | No, it reads the page you have open | Only on that page | One URL at a time |
| Google Places API | Yes, through code | No, there is no email field | API key, billing and code |
| Maps scraper with website enrichment | Yes, from the map as you move | Yes, from the website when one is published | Search, press Start, export |
You scrape emails from Google Maps in five steps: install the extension, search, press Start, move around the map, then save and export. Everything runs in Chrome on the Maps page you would open anyway. Prefer to watch it first? Watch the video tutorial on the extension page.
If you only need contact data from sites you already have, the same idea works on a single domain: see how to scrape a business website for contacts. For the wider version of the Maps workflow, read the free Google Maps data extractor guide.
It finds what each business chose to publish and misses the rest, so expect gaps: a scraper cannot invent an address that no page shows.
Typical gaps are businesses with no website, sites that only offer a contact form, and shared inboxes like info@ where you wanted a named owner. The first group is still useful: a business with no website is a good prospect for web design and booking tools, and you can find them with businesses without a website near you.
| Data point | Where it comes from | Always present? |
|---|---|---|
| Business name, category, address | Google Maps listing | Yes |
| Phone and website | Google Maps listing | When the owner added them |
| Rating and reviews | Google Maps listing | When the place has reviews |
| Business website | Only if the site publishes one | |
| Extra phones and WhatsApp | Business website | Only if the site publishes them |
| Social network links | Business website | Only if the site links them |
Each export has one column per data point, so the file opens cleanly in a spreadsheet or imports into tools like HubSpot, Pipedrive, Instantly, lemlist or Mailchimp.
Check them in four passes: remove duplicates, separate generic from personal inboxes, verify that each address can receive mail, and send in small batches. A raw scraped list always contains stale and shared addresses, and sending to them damages your domain.
The mailbox providers set the bar. Gmail's email sender guidelines ask bulk senders, defined as 5,000 or more messages a day to Gmail, to keep the spam rate reported in Postmaster Tools below 0.30% and to support one-click unsubscribe in marketing messages. Small senders are not exempt from the reputation logic, only from the formal threshold.
Collecting a business email that a company published is common B2B prospecting, but sending to it is regulated. The rules depend on where you send. This is general information, not legal advice.
United States. The CAN-SPAM Act, in 15 U.S. Code § 7704, requires clear identification that the message is an advertisement, notice of how to opt out, a valid physical postal address, and no commercial email more than 10 business days after an opt-out request. It also treats addresses harvested from a website that carries a no-transfer notice as an aggravated violation.
United Kingdom. The ICO's business-to-business marketing guidance explains that the PECR electronic mail rule does not apply to corporate subscribers, while sole traders and partnerships are treated as individuals. It also states that an address which identifies a person, even in their business role, is personal data under UK GDPR.
Elsewhere in Europe the rules are similar in spirit but differ by country, so read our guide to Google Maps scraping and GDPR and the overview on whether scraping Google Maps is legal before a first campaign.
Turn each address into a conversation about something specific to that business, since replies come from relevance. Vonsel keeps every captured business on a map, in a CRM with a Kanban board, calendar, notes, tags and custom fields, so the email stays attached to the context you need to write it.
For agencies and freelancers, that context is usually the Google reviews and the missing website. Use it to write a short first line that proves you looked, then adapt one of the cold email templates for local agencies instead of sending the same text to everyone.
On cost: the extension is free, the Free plan lets you try 200 businesses, and paid plans add larger limits, exports and AI. You can see the current options on the pricing page.
