Frequently Asked Questions
How does Cleanlist improve Lemlist campaign deliverability?
+
Cleanlist triple-verifies every lead email before your Lemlist sequence begins. Invalid, catch-all, and disposable addresses are flagged and can be excluded from campaigns, keeping bounce rates under 2% and protecting your sending domains from reputation damage.
Can Cleanlist find emails that Lemlist's built-in finder misses?
+
Yes. Cleanlist uses waterfall enrichment across 15+ data providers, which means if one provider does not have an email, the next one is queried automatically. This typically finds 30-50% more verified emails than any single-provider tool, including Lemlist's built-in finder.
Does Cleanlist add personalization data for Lemlist campaigns?
+
Yes. Beyond email verification, Cleanlist enriches leads with company name, industry, employee count, funding stage, and tech stack data. These are mapped to Lemlist custom variables so you can use them in dynamic email templates for personalized outreach at scale.
How fast does enrichment happen for Lemlist campaigns?
+
Individual lead enrichment completes in 30 to 60 seconds. Bulk list enrichment processes at roughly 1,000 leads per minute. Most teams run enrichment before launching a campaign, so there is no delay to the actual send schedule.
