How we ranked them
Each tool scores one point for each of these 6 criteria it meets. Ties go to the lower pay-as-you-go cost per 1,000; a tool with no published per-1,000 price sorts after those with one. Where our sources do not say, the cell reads "Not stated" and scores nothing. 67Leads is scored the same way from live figures, and we sell it, so weigh that.
- Is a Chrome extension. It installs in Chrome and works on the pages you browse.
- Finds local businesses by kind and place. You can get a list of a kind of business in a place, not only the page or domain in front of you.
- Returns email addresses. Email addresses are part of what it returns.
- Free allowance renews. The free part comes back every day or month, rather than once at sign-up.
- Email verification offered. It offers a check on whether an email address is deliverable.
- Published price per 1,000. A price per 1,000 rows is published, or can be worked out from a published plan.
