Sales EngagementAPI keyOne-way push

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.
