Push enriched leads straight into lemlist campaigns.
Cleanlist AI verifies and enriches your leads, then pushes them into the lemlist campaign you choose, deduplicated. Every address is checked before it reaches the campaign, and catch-all or risky addresses are flagged so you can hold them back. Connect with your lemlist API key. On our 500-lead benchmark the waterfall returned 98% verified work emails.

The Lemlist integration: a contact enriched in Cleanlist AI, with a verified work email, a phone number and a LinkedIn profile, is written into the matching Lemlist record. Empty fields are filled and existing values are kept.

Cleanlist AI adds each person to the Lemlist campaign you pick, and Lemlist sends from your team's own accounts. Sequences in Cleanlist AI is the other way to send.

custom A field you create once in Lemlist and pick during mapping. Everything else is stock.
Duplicates A lead already in the campaign is never added twice. Send to Sequencer updates it, and an agent skips it.
What you can do with Cleanlist AI and Lemlist
Cleanlist AI finds and verifies contact data across 25+ providers and writes it into Lemlist.
- 01
Push to any campaign
Send enriched, verified leads from Cleanlist AI directly into the lemlist campaign of your choice.
- 02
Protect deliverability
Verify every address before it's pushed, so your lemlist campaigns don't burn sender reputation on bounces.
- 03
Dedupe automatically
Cleanlist AI checks against existing leads so the same person doesn't land in a campaign twice.
- 04
From an agent
An agent's Add to sequence step can enroll each person it verifies in a lemlist campaign, and skips anyone already in it.
How it works
Paste one key, choose the destination, and the results land in the fields above. Lemlist is on Pro and Enterprise, and in the 14-day Pro trial.
- Step 01
Add your lemlist API key
Paste your key from lemlist's settings to connect in seconds. One key connects the whole workspace.
- Step 02
Pick a campaign
Choose the destination campaign and map the fields lemlist expects.
- Step 03
Enrich and push
Cleanlist AI verifies and enriches your leads, then pushes them with Send to Sequencer or an agent's Add to sequence step. No one is added to the same campaign twice.
What reaches Lemlist is already verified
Cleanlist AI looks up each record across 25+ providers and checks every address (syntax, domain, mailbox) before it writes anything. Catch-all and risky addresses come through with a flag on them.

98% verified work emails and 85% phone numbers on our 500-lead benchmark.
A demo of Clu, the Cleanlist AI agent, doing this for a whole list. Asked: Find the verified work email for everyone in Series B sales leaders Clu runs the tools, asks for confirmation before spending credits (Find work emails for 212 leads on Series B sales leaders, 212 credits), fills the list row by row and reports: 197 verified emails on the list, 15 not found. Want phone numbers for the 197 next?
How does the connection authenticate?
With your lemlist API key, found in your lemlist account settings. Paste it once and Cleanlist AI 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 address is verified during enrichment. Risky and invalid addresses are flagged so you can hold them back, and an agent's Add to sequence step skips them.
How accurate are the emails pushed to lemlist?
Cleanlist AI verifies every address through a 25+ provider waterfall before it reaches a campaign, working to a 98% verified work email spec with syntax, DNS/MX, and SMTP checks on each one, so your lemlist campaigns run on deliverable data.
