CIENCE review

Weak — 2 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 22% of the total score.

Benchmark — across the 88 other agencies evaluated in this discipline, this dimension runs Excellent 9 · Strong 36 · Adequate 28 · Weak 12 · Poor 3. The typical agency here scores Strong, and 73 of them score higher than this one.

What this dimension measures: The entire point of the engagement. THE TRAP: open rate is meaningless in 2026 (Apple Mail Privacy and bot-clicking inflate it) and raw send volume is a deliverability red flag, not a result — discount both heavily and demand cost-per-qualified-meeting and pipeline.

Scores low — Scores 4-5: 3+ recent case studies showing qualified meetings booked, positive reply rate, cost per qualified meeting, and downstream pipeline or closed-won, with named clients willing to be reference-called and a stated definition of what counts as 'qualified.' Scores 1-2: vanity volume ('we sent 80,000 emails,' '45% open rate'), meeting counts with no qualification definition, no referenceable client, or screenshots of reply notifications with no business outcome. Case studies dated 2024 or earlier as primary proof score 1-2; deliverability has changed too much.

What we found — Documented case: 2 of 10 promised weekly appointments after 7 months / ~$80k. Outcomes inconsistent.

On the record — “A mid-market client reports 2 of 10 promised weekly appointments after 7 months and ~$80k, citing database inaccuracy.” salesso.com ↗

pipeline — the dollar value of open, qualified deals sales is working. “Pipeline created” ties marketing to money, where lead counts don’t.

deliverability — deliverability: whether cold email actually lands in the inbox rather than spam. The tell is infrastructure talk — warmed sending domains kept separate from your main domain — because a burned domain outlasts the engagement.

Adequate — 3 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 20% of the total score.

Benchmark — across the 88 other agencies evaluated in this discipline, this dimension runs Excellent 8 · Strong 19 · Adequate 43 · Weak 11 · Poor 7. The typical agency here scores Adequate, and 27 of them score higher than this one.

What this dimension measures: The single most common way these agencies destroy value is by torching the buyer's domain reputation. THE TRAP: an agency that brags about huge monthly send volume ('we'll send 100k emails/month') is advertising a deliverability liability — the better shop sends less, lands in the inbox, and can explain exactly how it protects your domain.

Scores high — Scores 4-5: spins up dedicated sending domains (never the buyer's primary domain), warms inboxes before sending, configures SPF/DKIM/DMARC, keeps low daily volume per mailbox (roughly under 30-50/inbox), monitors inbox placement and blocklists, and isolates each client's infrastructure.

Scores low — Scores 1-2: sends from or risks the buyer's main domain, no warming, packs high volume per inbox, can't speak specifically to placement monitoring, or runs all clients through one shared sending setup.

What we found — Established infrastructure, but platform pivot reduces hands-on human oversight. That is between the two bands, which is why it scored Adequate.

Benchmark — across the 88 other agencies evaluated in this discipline, this dimension runs Excellent 7 · Strong 44 · Adequate 29 · Weak 7 · Poor 1. The typical agency here scores Strong, and 51 of them score higher than this one.

What this dimension measures: Garbage in, garbage out — and bad lists also wreck deliverability via bounces. waterfall enrichment / Clay-style workflows), bounce-scrubbing and suppression/exclusion handling, and use of intent or trigger signals to tighten targeting. THE TRAP: 'we have a database of 200M+ contacts' is a recycled-list red flag, not an asset — the value is precision and freshness for YOUR ICP, not size.

Scores high — Scores 4-5: a real ICP-discovery process, verified and enriched data (e.g.

Scores low — Scores 1-2: recycled scraped lists reused across many clients, a raw Apollo/ZoomInfo dump with no verification, no ICP discovery, or implied high bounce rates.

What we found — 140M+ contact universe, but reviewers cite database inaccuracy in practice. That is between the two bands, which is why it scored Adequate.

ICP — ideal customer profile: the specific kind of company or buyer an offer fits best. A vendor who asks for yours before quoting is showing their process.

What this dimension measures: Once deliverability is solved, the message is the lever. Ask to see the actual sequences they would send.

Scores high — Scores 4-5: research-based, human-written or human-edited copy, help sharpening the offer and positioning (not just sending whatever the buyer says), genuine personalization tied to the prospect's context, and structured A/B testing of angles.

Scores low — Scores 1-2: generic templates, fake personalization (a {{first_name}} token and a scraped company line), identical sequences reused across clients, or 'spray and pray.' THE TRAP: AI-generated slop marketed as 'personalization at scale' — high-volume, low-relevance copy that reads like a robot wrote it and gets the domain flagged.

What we found — More automation post-pivot; personalization depth uncertain. That is between the two bands, which is why it scored Adequate.

What this dimension measures: A booked meeting is worthless if it is unqualified or no-shows. THE TRAP: a high meeting count with a buried no-show/disqualification rate — the headline number looks great and the buyer's calendar fills with tire-kickers.

Scores high — Scores 4-5: qualification criteria agreed with the buyer up front, humans managing replies and objections, no-show and reschedule handling, clean CRM handoff, and reporting on lead-to-meeting and meeting-to-opportunity rates.

Scores low — Scores 1-2: books anyone who replies 'sure,' no qualification, dumps raw replies on the buyer to sort out, or hides no-show rates.

What we found — Offshore reps with little sales experience; qualification quality complaints. That is what the low band describes, which is why it scored Weak.

What this dimension measures: Pitch-vs-delivery bait-and-switch and offshore copy mills are the failure modes here. undisclosed offshore freelancers), and a sane number of accounts per operator. Ask explicitly: who writes my sequences, who manages my replies day-to-day, their LinkedIn, and how many other accounts they carry.

Scores high — Scores 4-5: a named account owner, clarity on who writes the copy and manages replies (in-house vs.

Scores low — Scores 1-2: a slick founder on the sales call with the account actually run by a junior plus an offshore VA, unnamed pooled staffing, or copy outsourced to undisclosed freelancers.

What we found — Mix of full-time and offshore outsourced teams; the pivot moves work toward tooling. That is what the low band describes, which is why it scored Weak.

What this dimension measures: marked up), and the buyer OWNS the sending domains, mailboxes, and data when the engagement ends. Note the model tension: pure pay-per-meeting can incentivize booking unqualified meetings to hit the count — pair it with the qualification dimension.

Scores high — Scores 4-5: a clear model (retainer, pay-per-meeting, or hybrid), month-to-month or short term with an out-clause, infra and data costs disclosed (passed through vs.

Scores low — Scores 1-2: long lock-ins with auto-renew, undisclosed markups on data/tools, or the agency keeping the domains and warmed inboxes hostage so the buyer can't leave without losing the asset. Unenforceable 'X meetings guaranteed or your money back' promises score 2 (usually marketing, not a real SLA).

What we found — $5k GTM setup + $2,499+/mo; many report $8-12k/mo with inconsistent results and misaligned retainer incentives. That is between the two bands, which is why it scored Adequate.

retainer — a fixed monthly fee regardless of hours or output — predictable, but worth tying to a defined scope.

SLA — service-level agreement: a contractual promise about speed or quality of delivery.

What this dimension measures: Hygiene factor with real downside. Necessary, rarely a differentiator on its own, but a hard fail if absent given the regulatory and deliverability exposure.

Scores high — Scores 4-5: works within CAN-SPAM / GDPR / CASL, honors opt-outs, uses sensible lookalike sending domains that shield the buyer's primary brand domain, and can articulate how it keeps the buyer off blocklists.

Scores low — Scores 1-2: shrugs at compliance, no opt-out handling, or sending practices that expose the buyer to brand-domain blocklisting and reputation damage.

What we found — Standard compliance posture. That is between the two bands, which is why it scored Adequate.
