I have watched the same founder conversation for years: 400 emails sent by hand, four replies, then agency websites showing prices from $397 to nearly $10,000 a month for what looks like the same service. It is not price gouging. The published 2026 pricing finally makes the difference readable.
The market runs from about $1,500 a month for entry-level done-for-you sending to $10,000+ for enterprise programs, with most serious engagements between $2,500 and $6,000 a month (outboundsystem.com, July 2026; leadium.com, 2026). Setup fees of $1,000 to $3,000 are typical, and infrastructure that proposals quietly exclude adds $500 to $2,000 a month on top (leadium.com, 2026).
The three bands are fairly consistent across sources:
- Under $2,500 a month: sending capacity. Template copy, basic data sourcing, thin infrastructure. Fine as a cheap test, not the same product as the tier above (outboundsystem.com, July 2026).
- $2,500 to $6,000 a month: the real work. Custom copy, verified data, deliverability infrastructure, a dedicated strategist, honest reporting. Multiple guides call this the sweet spot for most B2B companies (outboundsystem.com; leadium.com; cleverly.co).
- $5,000 and up: multi-channel. Email plus LinkedIn and sometimes calling on one accountable team, with vendors like Belkins and Callbox publishing $5,000 to $15,000 ranges (sequenzy.com, 2026).
Published vendor prices, read off their own sites in August 2026, include Belkins from $5,000 a month, CIENCE at $7,499 for the first month ($5,000 setup, $2,000 a month team, $499 a month platform), SalesRoads at $9,950 per four-week engagement, and Cleverly from $397 a month for LinkedIn outreach with $1,995 for cold email (outreachbloom.com, retrieved September 9, 2026).
The number that matters more than price is the denominator. Cold email reply rates have no single value because the denominator decides the result. Belkins' study of 7.5 million emails reports a 0.45% average against total sends and notes that 5% against openers can describe the same campaign (belkins.io, June 2026). Instantly's platform average is 3.43% (instantly.ai, 2026). Woodpecker's 20-million-email analysis splits personalization: 18% for personalized campaigns versus 9% for templates (woodpecker.co, 2026).
For agency evaluation this is decisive. If the pitch leads with volume, the data argues against you: campaigns of 50 or fewer recipients average 5.8% reply rates versus 2.1% for campaigns of 500+ (Belkins data summarized at autobound.ai, 2026). The agencies winning in 2026 sell smaller, better-targeted campaigns with signal-based personalization, and they publish their numbers against total sends.
Red flags worth keeping: infrastructure excluded from the retainer, commission tiers without qualification definitions, no written deliverability standard, and guarantees on the wrong metric. A serious agency will put a spam-rate standard under 0.10% with a kill-switch in writing (leadium.com, 2026).
Ask five questions before signing: what denominator do you report replies against; is infrastructure in the price and do we own the domains; what is your written spam-rate standard; show two current same-ICP clients at this price tier with honest numbers; and what happens at month three if the trend is flat.
The DIY line is more generous than most people expect. Under about $2,000 a month, tools plus a small targeted list is usually the better test. In the $2,500 to $6,000 band, an agency earns its fee through verified list strategy, deliverability operations, and reporting you can audit. Whatever you choose, insist on the total-sends denominator, because it is the only one you can verify independently.

The part that usually gets skipped in agency threads: 58% of replies come from email one of the sequence (Instantly). If an agency's reporting shows a high reply rate but cannot tell you which step produced it, you cannot tell whether follow-ups are doing the work or the first email is. Sequence-level reporting is the transparency test that pricing pages hide.😀
