Early-stage SaaS founders do their own sales, and their contact data is a patchwork: waitlist form exports, beta sign-ups, community DMs, and hand-built prospect research. Before a founder can run a clean onboarding sequence or a targeted outreach batch, that patchwork needs to become one deduplicated, qualified list.
This workflow helps founders extract addresses from every early channel, drop personal and disposable accounts that won't convert, dedupe against existing users, and export a clean list for founder-led outreach.
The workflow
1
Extract from waitlists and sign-ups
Paste waitlist exports, beta sign-ups, and research lists into the bulk extractor to collect every address.
2
Qualify to business accounts
Filter to business domains and drop disposable addresses that signal low-intent sign-ups.
3
Dedupe against current users
Compare the list against your existing user export so you don't pitch people who already signed up.
4
Export for outreach
Convert to CSV ready for your outreach tool or onboarding sequence.
