Research-backed first lines for outbound agencies and B2B founders. Structured prospect research, QA-scored openers, CSV delivery in 24 to 48 hours.
Dossier is a B2B service that researches each prospect and writes three QA-scored cold email openers you import into Smartlead, Instantly, Lemlist, or any CSV-based sequencer. We do not send emails or access your inboxes.
For every prospect, we extract a verifiable public signal (LinkedIn post, launch, hiring news, or company update), draft three opener variants, run a separate QA pass (1 to 5 scale), and return a CSV with signals, scores, and thin-profile flags within 24 to 48 hours for a 100-prospect pilot.
Each line cites a real public signal instead of name-and-title filler, which is why pilot campaigns moved from 3.1% to 9.6% reply rate in early case studies.
Low-specificity openers are flagged or rewritten so your reps never import slop into a warmed domain.
CSV delivery only. You keep deliverability, volume, and offer control while we handle prospect research and opener QA.
Dossier is a done-for-you research service for outbound agencies and B2B founders. We review public signals per prospect, including LinkedIn posts, product launches, hiring moves, and company news, then write three QA-scored first lines you import into your sequencer.
Every delivery includes the research signal, confidence scoring, and thin-profile flags. Typical pilot turnaround is 24 to 48 hours for 100 prospects. No inbox access, no campaign permissions, and no credit card required to start the free pilot.
Dossier does not send emails on your behalf. You keep full control of volume, offer, and deliverability while we handle prospect research and opener quality assurance.
We capture what the prospect publicly said in the last 90 days and anchor the opener to a specific idea, not a job title.
New features, rebrands, and ICP changes give concrete hooks that generic templates miss.
Open roles and leadership hires signal priorities you can reference without flattery.
Press releases and credible third-party coverage help us write fact-checked openers with traceable signals.
We connect the prospect's situation to patterns seen across similar B2B companies so the line reads researched, not generated.
Upload a CSV with names, LinkedIn URLs, company names, and emails. Clay, Apollo, and manual lists all work.
Each prospect gets three opener variants plus the signal used, a QA score from 1 to 5, and a confidence flag.
Deliveries are formatted for Smartlead, Instantly, Lemlist, EmailBison, Clay, and Apollo CSV workflows.

No. Bulk AI generation produces detectable slop. The value is structured lead research, signal selection, multi-variant generation, and a separate QA scoring pass. Openers that fail QA get rejected or retried before you see them.
No. We only deliver personalized first lines in a ready-to-import CSV. You keep full control of your inboxes, sending sequencer, offer, and volume. No campaign access requested or required.
Low-confidence prospects are flagged in the deliverable. You see which leads have thin signal and decide whether to pull them, use the lower-confidence opener, or re-queue them.
Pilot batch: typically 24 to 48 hours for 100 prospects. Ongoing runs for larger batches can be scheduled at regular intervals.
We review results together. If the openers beat your baseline, we discuss a rollout plan covering pricing, volume, and cadence. No automatic billing or commitment from the pilot.
Outbound agencies, B2B founders doing cold email, and SDR teams with large prospect lists where reply rate is the primary KPI. Best for companies targeting decision-makers at 10 to 200 person companies.
