LeadSignal lives on LinkedIn, Sales Nav, Apollo, and ZoomInfo. One click returns a deliverability-checked work email plus a personalized opening line your AE didn't have to write.
No credit card · Bounces auto-refunded · Chrome + Edge
No more juggling Apollo + Hunter + Lavender. The whole workflow runs from a single browser button.
LinkedIn, Sales Nav, Apollo, or ZoomInfo. The LeadSignal popup detects who you're looking at.
Our server runs a 4-provider cascade (Hunter → Dropcontact → Datagma → FindyMail) until it returns a verified hit. You only spend a credit when an email comes back.
We read the prospect's last 3 LinkedIn posts and Claude writes a one-sentence cold open that references something they actually said.
4-provider cascade. ~95% deliverability. Bounces are refunded, no questions.
Claude-written first line from the prospect's last 3 posts. Tone presets per persona.
Send + follow-up engine with working-hours gating and per-day caps so you don't get account-flagged.

For full-time SDR/AE work.
For sales teams of 3+.
The outreach engine ships with conservative defaults — randomized delays, working-hours gating, daily caps, and skip rate. Almost every account ban from "automation" is from tools that send 100+ requests/day with zero pacing. We default to 20-50/day.
The 4-provider cascade (Hunter → Dropcontact → Datagma → FindyMail) returns a "verified" status only when SMTP-level checks pass. Real-world deliverability sits in the 92-96% range. Any hard bounces inside 7 days are credited back automatically — no support ticket required.
From the prospect's last 3 public LinkedIn posts, fetched in your browser session (we don't proxy your LinkedIn account). Claude then writes a single sentence that references something they actually said — not "I see you're a VP at X" generic.
No. LeadSignal is fully usable from LinkedIn alone. If you already pay for Apollo or ZI, we just use them as a richer list source and push the contacts into our sequence engine.
Enrichment data is sourced from providers with their own consent + opt-out infrastructure (Dropcontact in particular is fully GDPR-compliant). Every prospect can email us to be added to a global suppression list. Details in the privacy policy.
Yes. No annual contracts. Prorated refund if you cancel inside the first 14 days.
