Phone, email and address unlock in Mantis
16,744 businesses with WhatsApp on their website, out of 1,29,173 business websites we have read ourselves. This page is the WhatsApp marketing leads list: who they are, where they are and what their sites show — with contact details unlocked in Mantis.
Updated 24 October 2026 · For whatsApp Business API providers, chatbot builders and WhatsApp marketing agencies.
A business that puts a WhatsApp button on its own website already sells through WhatsApp — it is not a new channel to convince them of, it is one they are running by hand. Automation, catalogues and broadcast are the upgrade.
We detect WhatsApp links on the website itself.
Built for whatsApp Business API providers, chatbot builders and WhatsApp marketing agencies.

From our own reads of each business's website. Mantis fetches the site, detects the platform, tracking tags, booking, careers pages, WhatsApp links and contact details, and stores what it found with the date. Nothing here is bought from a data vendor.
Yes, where the business publishes one. Of the websites we have read for this list, 81% show at least one email, and 2,025 name a decision-maker. Emails are graded: a named person's address above a role inbox above a generic one.
Not from this page — names are shown here because they are already public on Google Maps; phone numbers, emails and addresses are what you unlock in Mantis, a business at a time or in bulk, and export from there. Free to start: every account gets 500 credits once.
These are businesses, contacted at their published business details. B2B outreach is generally allowed, but the rules differ by country — the UK and EU expect a legitimate-interest basis and an easy opt-out, India's DPDP Act covers personal data. Mantis adds unsubscribe handling to email campaigns; check the rules for the countries you sell into.
A bought list is a snapshot — often years old, priced per record, and blind to businesses without a website. This one is built from live map data and our own website reads, and Mantis re-checks a business when you use it, so you are not paying for closed shops and dead inboxes.
Free to start with 500 credits. Tell Mantis what you sell and where — it builds the list, finds the contacts and drafts the outreach.
