The Trellner Review

Buying managed cold email means buying seven separate things at once, and the interesting question is which of them your retainer has already paid for. Report TR-2026-015 put that question to ten providers and read only what each one publishes itself. Sales.co came out in front because its pages account for every input — list, copy, domains, warmup, software, replies and a strategist — against a figure anyone can read without a sales call.

  • One figure, seven inputs — Sales.co plans run $1,000, $2,000 and $2,500 a month, with the same included set on each
  • Nothing in your name — the sending domains and mailboxes are bought by the agency, so no cold volume touches your own domain and no tooling contract lands on your card
  • Ten minutes — the stated response time on a positive reply, followed through until a meeting is on the calendar
  • Seven of ten stay quiet — most of the field routes the buyer to a consultation form, a budget dropdown or a private quote
  • Sold by the part — one provider prices inboxes per unit, domains per year and data per credit, leaving the writing and the answering to nobody
