Push enriched leads straight into lemlist campaigns.
Cleanlist verifies and enriches your leads, then pushes them straight into the lemlist campaign you choose, deduplicated and ready to send. Its 15+ provider waterfall verifies 98% of work emails before anything reaches a campaign, well above the 70 to 80% typical of single-source tools, so you protect sender reputation instead of burning it on bounces. Connect with your lemlist API key in seconds.

Lemlist integration FAQ
How does the connection authenticate?
+
With your lemlist API key, found in your lemlist account settings. Paste it once and Cleanlist handles the rest.
Does it avoid duplicate leads?
+
Yes. Cleanlist deduplicates against the leads already in your campaign before pushing, so contacts aren't added twice.
Are emails verified before they're sent?
+
Yes. Every lead is verified during enrichment, so invalid and risky addresses are filtered out before they reach a campaign.
How accurate are the emails pushed to lemlist?
+
Cleanlist verifies every address through a 15+ provider waterfall before it reaches a campaign. A public 500-lead benchmark measured 98% verified work emails, well above the 70 to 80% typical of single-source tools, so your lemlist campaigns run on deliverable data.
