data quality

Your AI agent is only as good as its data.

Scalelist finds verified professional emails and mobiles, so fill rates stay high where single-database tools have coverage gaps.

Every result is verified and the junk is filtered out before it ever reaches your agent’s output, so your AI sales assistant acts on data you can actually use.

Feed your agent good data only.

Verified work emails

Triple-checked, <5% bounce rate.

Verified work emails

Validated against real line ownership.

Bad data filtered out

Before it reaches your agent’s output.

Real prompts and skills your team can paste today. Use Scalelist as an AI prospecting tool, or wire it into your AI SDR agent.

Build a lead list from a description

Describe who you want; the AI finds them and returns a clean table with verified emails and phones.

Goal: a verified, deduped lead list, one decision-maker per company. Target: exactly 25 people whose current title is one of ["VP Marketing","Head of Marketing","CMO"] (fall back to "Marketing Director" only if none exist at that company), at B2B SaaS companies, HQ country = United States, headcount 50 to 200, founded 2015 or later. Process: 1. Build a 30-company shortlist (over-fetch to cover misses) and print it as a numbered list with company + employee count. STOP and wait for my "go". 2. After "go", pick the single best-fit person per company (one per company, no duplicates). 3. Enrich with Scalelist: verified work email + direct mobile. Cap spend at 60 credits; if you'd exceed it, stop and ask. Output table, columns in this exact order: Rank | First name | Last name | Title | Company | Employees | HQ city | Website | LinkedIn URL | Email (lowercase) | Email status (valid/risky) | Mobile (E.164). Rules: include ONLY rows with a valid email; drop risky/not-found; sort by Employees descending; never fabricate a value (leave blank + note). Finish with: rows returned, emails found, mobiles found, credits used.

Enrich a CSV without leaving the chat

Drop a CSV of LinkedIn URLs, names, or domains; the AI enriches every row.

I'm attaching a CSV. Identifier per row is either (Full name + Company domain) OR a LinkedIn URL. Process: 1. Tell me the row count detected and which identifier you'll use. If >200 rows, process in batches of 100 and confirm after each batch. 2. Enrich every row with Scalelist: verified work email + direct mobile. Verify each email and label it exactly valid / risky / not_found. Output: return my ORIGINAL columns and row order unchanged, then append, in this order: Email (lowercase) | Email_status | Mobile (E.164) | Mobile_status (found/not_found) | Reachable (Yes if Email_status=valid OR Mobile_status=found, else No) | Note (short reason when not reachable). Then print a summary: rows processed, valid emails, risky, not_found, mobiles found, reachable %, credits used. Misses cost 0 credits, never delete unreachable rows, only flag them. Finally export as "enriched_<original-filename>.csv".

Write outreach that doesn't look like outreach

The AI pulls career history and company context, then writes tailored emails, DMs, or call scripts.

Write a personalized cold email for each of these 10 enriched contacts. My context: I sell [product] to [audience]. Primary outcome: [metric/result]. Proof point: [1 customer + result]. CTA: interest-based, not a meeting ask. For each contact, mine their Scalelist profile for ONE concrete, verifiable hook, in this priority: (1) job change in last 6 months, (2) company signal [hiring/funding/launch], (3) specific role scope. If none exist, mark "needs manual review" and skip, never fabricate a hook. Hard rules: subject ≤ 42 characters, no emoji; body 50 to 90 words; ≤ 9th-grade reading level; plain text; exactly one CTA phrased as a question; banned phrases: "hope this finds you well", "quick question", "I noticed you're the [title]", "synergy", "circle back", "game-changer". Output table: # | Name | Company | Hook type used | Subject | Body | Word count.

Map an org before your first call

Company or domain in; org chart, hierarchy, and who to contact first out.

Map the GTM org at [company.com] so I know exactly who to open with. My offer: [what I sell + outcome + who owns it]. Process: 1. Use Scalelist to find current employees in Sales, Marketing, and RevOps/Operations at this domain. 2. Group by function; within each, rank by seniority: C-level > VP > Senior Director > Director > Senior Manager > Manager > IC. 3. Recommend a Primary and Backup first-contact for my offer, each with a one-line reason tied to budget or problem ownership (not just seniority). 4. Enrich ONLY the Primary and Backup with verified email + mobile (max 2 credits). Output: (A) org chart as an indented list grouped by function, each person = Name, Title, tier; (B) "Contact first" block with Primary {name, title, why, email, mobile} and Backup {same}. Edge case: if the company has <10 employees or no GTM titles, say so and name the founder/CEO as the entry point. End with credits used.

Build a sequence from scratch

The AI designs timing, channel mix, branches, and a breakup message.

Build a 5-touch outbound sequence for these 20 enriched leads. I sell [product]; outcome [result]; proof [stat]; CTA style = soft/interest-based. Exact cadence (business days): Day 1 Email, Day 2 LinkedIn DM, Day 4 Email, Day 6 LinkedIn DM, Day 9 Email (breakup). Angle per touch (no repeats): T1 problem hook → T2 one-line credibility → T3 new proof/use case → T4 light social-proof nudge → T5 breakup with an easy out. Personalize every touch from each lead's Scalelist profile (role, company, signal); the T1 opening line must be unique per lead. Emails 50 to 90 words, DMs ≤ 45 words, one CTA each. Output: one master table. Lead | Company | Touch | Channel | Send day | Subject (emails only) | Message | Word count. Then: (a) the 1 variable I should A/B test first and why; (b) any lead with too little data flagged "generic, needs review" rather than guessed.

Prep for a meeting in 30 seconds

LinkedIn URL or name in; a full brief out.

I have a call with [name] at [company] in 10 minutes. Pull their profile + company via Scalelist and brief me in EXACTLY this structure, total ≤ 220 words, no fluff: 1) Who they are, title, seniority tier, time in current role, previous role/company (1 line). 2) Company, what they sell, segment, employee band, and 1 recent signal with rough date. 3) Their likely top 2 priorities + 1 pain for this exact seat. 4) Fit, one sentence mapping [my product] to point 3. 5) Opener, one tailored line referencing point 1 or 2 (not generic). 6) Discovery, 3 questions ordered easy → hard, each ≤ 20 words. 7) Landmine, 1 objection/sensitivity common to this persona + a one-line counter. If any field is unknown, write "unknown, not in data" rather than guessing. Don't enrich email/mobile.

Push to CRM in one prompt

The AI detects your CRM, maps fields, checks duplicates, and pushes.

Push these 20 enriched contacts to my [HubSpot/Salesforce/Pipedrive]. Process (do NOT write anything until step 3 is approved): 1. Dedupe: match existing records on email (exact, case-insensitive); if no email, match on (Last name + Company domain). 2. Show me a preview: New (n), Duplicate (n, with matched record name+ID), Conflict (n, where my data differs). Wait for my approval. 3. On approval: create New; for Duplicates only fill BLANK fields (never overwrite); skip Conflicts and list them. Field mapping: First name, Last name, Title, Company, Email (lowercase), Mobile (E.164), LinkedIn URL, Lead source = "Scalelist MCP". Apply tag/list "Scalelist. Q2 2026". Add a note per record: "[industry], [employees], fit: [one line]". Output: summary table. Created | Updated (blanks filled) | Skipped duplicate | Skipped conflict | Failed (with reason).

Source candidates like a headhunter

Describe a role; the AI searches, enriches, and tiers candidates.

Source 15 candidates for: [Senior Backend Engineer]. Must-have: [Python] + [5+ yrs backend]. Nice-to-have: [AWS, Kubernetes]. Location: [remote, France or CET ±2h]. Hard exclude: anyone currently at [our company] or [competitors]. Process: 1. Build a 20-name shortlist (over-fetch); print Name | Current title | Company | Location; wait for my approval. 2. On approval, enrich each with Scalelist (verified email + mobile; cap 30 credits). 3. Score fit 1 to 3 (1 = best) against must-haves only; nice-to-haves break ties. Output table, sorted Tier 1→3 then years desc: Tier | Name | Current title | Company | Location | Years relevant | Must-haves met (y/n) | Why (≤15 words) | Email | Email status | Mobile (E.164). Flag candidates with an "open to work"/recent-departure signal as "⚡ priority". End with count per tier + credits used. Never include an excluded company.

Find contacts that look like your best customers

Share a converted contact; the AI reverse-engineers the ICP and finds lookalikes.

Seed (a customer who converted last month): [LinkedIn URL or Name + Company]. Process: 1. Profile the seed + company via Scalelist and output a 1-line ICP: industry | employee band | role+seniority | region | 1 to 2 buying signals. 2. Wait for my "go" / edits on that ICP. 3. Find 10 lookalike contacts at OTHER companies (exclude the seed's company and [my company]); one per company. 4. Score each 0 to 100 on ICP fit, weighting: role/seniority 40, industry 25, company size 20, region 15. Enrich ONLY contacts scoring ≥ 60 (top 5 max) with verified email + mobile. Output: (A) the final ICP line; (B) ranked table sorted by score desc: Rank | Name | Title | Company | Employees | Region | Match score | Score reason (≤15 words) | Email | Mobile (E.164). Rules: don't enrich anyone < 60; if fewer than 10 hit the bar, return only those and say why. End with credits used.

Scalelist works with any MCP-compatible client: Claude (Desktop and web), ChatGPT via its MCP connector, Cursor, and any other AI assistant or agent that supports the Model Context Protocol. Add the Scalelist MCP server once by pasting the connector URL (https://mcp.scalelist.com/mcp) and it's live everywhere you work.
Once connected, your AI assistant runs your whole prospecting stack from chat: find verified work emails and direct mobile numbers, enrich a CSV or a list of LinkedIn URLs, build lead lists from a plain-English description, map a company's org chart, write personalized outreach, prep meeting briefs, and push enriched contacts to your CRM. It turns Claude or ChatGPT into an AI sales assistant on top of verified B2B data.
Scalelist verifies every professional email and mobile number before it reaches your agent. Email accuracy is around 99%, bounce rates stay under 5%, and coverage reaches up to 95% of B2B emails and mobiles worldwide. The database is refreshed weekly, so you act on current contacts, not stale ones.
You never pay for misses. Credits are only spent when Scalelist returns verified data. If we can't find a valid email or mobile for a contact, that contact is free. Verification is included in the credit, so a valid result is already checked for deliverability.
