Cold Email

Find Emails at Lemlist Companies

Lemlist is a personalized cold email and outreach platform. Find and verify professional email addresses at companies using Lemlist — from decision makers to company-wide contacts — with real-time SMTP verification.

Why target Lemlist companies?

Technology usage is one of the strongest intent signals in B2B outreach. Companies using Lemlist share a common profile: they've invested in a specific cold email solution, which tells you a great deal about their size, priorities, and buying behavior.

Knowing a company uses Lemlist lets you write a more relevant pitch, reference their existing stack in your outreach, and identify which buyer persona is most likely to respond — before you send a single email.

How to find emails at Lemlist companies

1

Identify Lemlist companies

Use a tech stack detection tool (BuiltWith, SimilarTech, Wappalyzer) to export a list of companies using Lemlist. Each company comes with a domain.

2

Find decision-maker emails

Pass each company domain to emailfinder.dev's decision-maker endpoint to get the email, name, and title of the right buyer — CEO, VP Sales, CTO, or Head of Marketing.

3

Or find all company emails

Use the company endpoint to return up to 20 verified email addresses per domain — useful for multi-threading your outreach across multiple stakeholders.

4

Verify and send

Every result is verified live via SMTP before it's returned. You only pay for confirmed deliverable addresses, so your list is clean before you send a single email.
