Scalelist finds the work email and mobile number of a prospect, then charges a credit per result rather than a flat fee per user, so a small outbound team can pull a large list without buying seats it does not use.

One credit buys an extracted lead or a found email; a verified mobile number costs 10 credits, and the 5,000-credit plan covers 5,000 emails or 500 mobiles a month.
Triple verification, bulk CSV enrichment, the Chrome extension, a mobile finder and API access with Zapier and Make are included on every plan, with unused credits rolling over.
Annual billing during the sale gives 12 months for the price of 7, so the 5,000-credit plan costs $1,433 for the first year instead of $2,388, covering 60,000 credits.

Larger volumes are handled as custom plans, and every plan can be tried free before billing starts.
