Fentner Business Spotlight

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

Which cold email agency actually suits a consultancy, an advisory practice, an accounting firm or a law firm selling B2B work? We graded nine of them on segment evidence, per-prospect writing, reply speed and the cost of starting small. Sales.co places first as the only one carrying all four.

  • Two pages, not a badge — a consultants page and a professional services page that name titles, triggers and source lists, including 105,224 lawyer records and 50,600 accountants
  • One Email Per Prospect — research on the firm and the reader before a word is written, credited with 3.2x the reply rate of templates
  • Ten minutes on a warm reply — worked personally to a booked meeting, the only stated response time among the nine
  • Published consultancy campaign — 174 interested replies and 23 referrals off roughly 52,000 emails into non-profits, universities and research institutions, with formal tone outperforming informal
  • Priced for a small practice — $1,000 a month, month by month, nothing to start
  • Where the others stop — no price on the Belkins or SalesHive consulting pages, a $50,000 contract floor at Growth Rhino, and no segment page at all from the remaining five
