How to Find & Verify Unlimited Emails in Clay Without Paying Per Credit

1. Outbound prospecting at scale

You're pulling 5,000-50,000 prospects per week from LinkedIn Sales Nav, Apollo, or your ICP filters in Clay. Each one needs an email. With credit-based providers, that's $250-2,500/week in enrichment costs alone.

With RevoScale as your first waterfall touch, you find ~80% of those emails for $0 extra (flat rate). Only the remaining 20% hit your paid providers. Then run all emails through RevoScale verification (also unlimited) before pushing to Instantly or Smartlead.

2. Inbound lead enrichment

A lead fills out a form with just their name and company. Your sales team needs their direct email, phone number, and company data before the first call. With Clay + RevoScale, the enrichment happens automatically: the form submission triggers a Clay workflow that hits RevoScale's API to find the work email, verify it, and populate the lead record in your CRM.

3. CRM data hygiene & re-verification

Your CRM has 100,000 contacts. How many of those emails still work? People change jobs, companies rebrand, domains expire. Pull your contacts into Clay, run them through RevoScale's verifier (unlimited, remember), and flag the invalid ones. Then use the Email Finder to replace stale addresses with current ones.

This is where unlimited verification really shines. Verifying 100,000 emails with a credit-based provider costs $100-1,000. With RevoScale, it's included in your flat monthly rate.

4. Account-based marketing (ABM) list building

You have a list of 500 target accounts. For each account, you need to find 5-10 decision makers and their emails. That's 2,500-5,000 email lookups per campaign. With per-credit pricing, that's $12-50 per ABM campaign. With RevoScale, it's $0 extra because you're already paying your flat monthly rate.

5. Event & conference follow-up

You come back from a conference with 2,000 badge scans. Half have emails, half don't. Import the list into Clay, use RevoScale to find the missing emails from names + company domains, verify everything, and push to your sequencer the same day. Speed matters — the faster you follow up, the higher the conversion.

6. Hiring & recruiting outreach

Recruiters and talent teams use Clay to build candidate lists from LinkedIn. The challenge is finding personal or work emails for passive candidates. RevoScale's Personal Email Finder and Email Finder APIs work in Clay to surface both personal and professional addresses — unlimited lookups, no per-candidate cost.

Always put RevoScale first in your waterfall

Since RevoScale is unlimited, it costs nothing extra per lookup. Let it handle the first pass. Only rows where RevoScale returns null should fall through to credit-based providers like Clearbit, Hunter, or Apollo. This alone can cut your enrichment spend by 60-80%.

Use verification as a quality gate

Regardless of which provider found the email, always run it through RevoScale's verifier before outreach. Filter for is_reachable = "safe" to only send to verified, deliverable addresses. This keeps your bounce rate near zero and protects your sender reputation.

Filter before enriching to save Clay credits

Use Clay's conditional filters to only run the enrichment on rows that are missing an email. This avoids redundant API calls and keeps your Clay workflow efficient. RevoScale's API is unlimited, but Clay still counts each enrichment step.

Chain all RevoScale tools in one Clay table

You're not limited to the Email Finder and Verifier. Add additional HTTP API steps for RevoScale's Personal Email Finder (/api/v1/personal-email-finder) and Mobile Phone Finder (/api/v1/mobile-phone-finder) to build complete contact profiles without leaving Clay.

Use confidence scores for lead prioritization

RevoScale returns a confidence score (0-100) with every email found. Use Clay's filtering to create a confidence >= 90 column for your top-priority outreach list, and a separate bucket for lower-confidence leads that might need manual review.
