Fentner Business Spotlight

Pricing changed on 2026-09-28. Plans now start at $2,000/month.

Many outbound retainers quietly depend on a data tool the client pays for separately. We checked nine cold email agencies for the opposite arrangement, where the agency does the sourcing, the cost sits in the fee and the client can take the contacts away. Sales.co came out on top.

  • Sourcing method stated — a waterfall that continues past standard databases, credited by Sales.co with 42% more valid contacts
  • Beyond LinkedIn — decision makers without a profile still come back with an email address and a mobile number
  • Exclusions first — the client's do-not-contact file is applied before the first send
  • No per-record billing — up to 1,000 intent leads at $1,000 a month, or up to 20,000 profile matches at $2,000
  • Lists sold separately — $295 per verified B2B list for buyers who want data only
  • Gaps elsewhere — a $499 platform charge at CIENCE, a price given only on a call at SalesHive, no figure at Belkins
