What is the best free tool to find business emails

buzzlist.io gives you 100 revealed business emails a month, free, with no credit card and no end date. You search around 270 million people by title, industry, company size and location, see who has an email before you spend a contact, and save lists for later. What Free does not include is the AI: Buzz picking people from a sentence, Sales Briefs and written emails are paid.

What Buzz does with that

  1. Say who you want

    Search with filters: job title, industry, company size, state, city or ZIP radius. Every result shows whether a business email, personal email, mobile or direct phone is available.

  2. Buzz finds and reveals

    Ranked people with a reason each. Business email, personal email, mobile and direct phone where available. 100 reveals a month free, then flat monthly plans with no seats.

  3. Buzz writes

    Four emails per person from their real website, threaded, spaced over two weeks. Buzz Send is available in the customer portal with a gradual sending ramp.

Questions people ask next

What counts as using one of the 100?

Only a reveal: when Buzz shows you an email or phone you did not already have. Searching, filtering and saving never count. A person with nothing to reveal costs nothing.

Are the free emails verified?

The main set of people is not deliverability-checked. Growth and Scale add deeper business profiles with checked work emails and a status you can see before sending.

Does the free plan expire?

No. 100 new contacts arrive at the start of every month for as long as you use it.
