LeadSignal - Verified Emails + AI Cold Openers

Turn any LinkedIn, Sales Nav, Apollo, or ZoomInfo profile into a verified email plus an AI cold-opener from their last 3 posts.

LeadSignal is a lead-research extension built for sales reps who already spend their day on LinkedIn, Sales Navigator, Apollo, or ZoomInfo. One click returns a deliverability-checked work email. A second click drafts a personalized opening line from the prospect's last 3 LinkedIn posts. WHAT YOU GET - Verified email finder running a 4-provider cascade (Hunter, Dropcontact, Datagma, FindyMail). Bounces are auto-refunded within 7 days. - AI cold opener (Claude) that reads the prospect's recent posts and writes a one-sentence opener that references something specific they said. - Throttled outreach engine with daily caps, working-hours gating, and randomized delays so your account stays safe. - Native bridge to Apollo and ZoomInfo for teams already paying for those tools. - Pipeline view at leadsignal.com for sequences, replies, and team reporting. HOW IT WORKS 1. Open a prospect's profile on LinkedIn, Sales Nav, Apollo, or ZoomInfo. 2. Click the LeadSignal icon. The popup detects the profile and lets you press "Find email" or "Draft opener". 3. Find email runs our verified-email cascade server-side and returns the deliverability-checked address in 2-4 seconds. Only verified results consume a credit. 4. Draft opener reads up to 3 recent posts from the prospect's Activity tab and generates a personalized first sentence you can paste into Gmail, Outlook, or your sequencer. WHO IT'S FOR - Solo founders running their own outbound - SDRs and AEs who want better reply rates without writing every opener by hand - Sales managers running teams of 3 or more PRICING - $49/mo Starter (500 credits) - $99/mo Pro (2,000 credits) - $149/seat Team (5,000 credits, 3+ seats) - Free trial: 25 credits, no credit card required PRIVACY LeadSignal does not log into your accounts and does not transmit private messages.
