Put verified contacts into every Outreach sequence.
Cleanlist verifies and enriches Outreach prospects so every sequence reaches a real inbox and a real direct dial. Its 15+ provider waterfall verifies 98% of work emails and finds 85% direct dials, well above the 70 to 80% email and 30 to 60% phone coverage typical of single-source tools. Every prospect syncs back with the firmographic and AI fields your sequences need to personalize.

Outreach integration FAQ
How does this protect deliverability?
+
Cleanlist verifies each address before it reaches a sequence, catching invalid and catch-all domains that would otherwise bounce and hurt your sender reputation.
Can I enrich prospects already in Outreach?
+
Yes. Enrich existing prospects in any sequence or across your whole database, and records update in place without disrupting active cadences.
What data gets added?
+
Verified work emails, direct dials, job title and seniority, company firmographics, and any custom AI columns you configure.
How accurate are the emails and phone numbers?
+
In a public 500-lead benchmark, Cleanlist's 15+ provider waterfall verified 98% of work emails and found 85% direct dials, versus 70 to 80% email and 30 to 60% phone from single-source tools. That accuracy is what keeps Outreach sequences out of the bounce folder.
