Cleanlist AI Reviews

The lead identification is top-notch, I can't argue with it. It picks up emails and phone numbers that Dropcontact doesn't find.

The only issue-- and it's really a non-issue, are the limits.

I wish I could use it for all my lead research, but I find myself using it sparingly-- because these are the big guns.

So it still get a 5 star review because the alternative is literally £100/mo.

Tier-5 (API) buyer, reviewing the API and support experience with dates, so you can judge for yourself.

The enrichment itself works: the waterfall found verified emails and we only paid for hits. Five tacos for that alone. The rest is why this review isn't five.

The API design has a trap. v1's POST /enrich/bulk writes every result into one system list ("Extension Leads") with no destination parameter. That list is capped at 500, delete-protected, and when it fills, every enrichment call returns 403 lead_cap_reached. Your pipeline just stops. The portal can't clear it: "Delete leads" errors on that list (we tested with 500 rows and with 2), and there's no move-to-list, only copy.

The support timeline, from the ticket:
- Jul 28: reported the blocked pipeline with full detail. The AI bot's answer recommended a "move to another list" feature that does not exist in the product.
- Jul 28: asked for a human. Got "the team will be back in 2 hours."
- Jul 30: a support rep said he was raising it with the CTO.
- Aug 4: nothing. Asked again.
- Aug 8: told we were "using the wrong endpoint" and should use the new v2 API.
- Aug 9: we tested v2 with a real contact and replied the same day: v2 lets you pick the destination list, but its status endpoint returns no per-contact results at all ("result": null, no linkedin_url, no provider), so there is no way to verify who was actually found. We offered a workflow_id to reproduce. The CTO joined and said "I'm looking into this."
- Aug 13: silence. Asked again.
- Aug 18: gave a final date of Aug 21 before posting this review.
- Aug 25: still nothing. Total: four weeks, zero fixes delivered by support.

We unblocked ourselves: v2's list endpoints let us drain the full list with our own API key, which support apparently didn't know when telling us it was impossible. That's also the fix for anyone else hitting the 403: DELETE /api/v2/lead-lists/{id}/leads works on "Extension Leads."

What's still broken today: safe enrichment (v1, the only version that returns per-contact results) is still hard-wired into a capped list, so the jam will recur for every API customer at 500 contacts.

I'll update this review the day either fix lands: per-contact results on the v2 status endpoint, or a lifted cap on the v1 list. Both are small. The ticket has everything needed to reproduce.

I’ve tried some of the bigger names in this space, including Apollo and Clay, so I wasn’t expecting much from a lifetime deal. Cleanlist has truly surprised me. The waterfall enrichment is probably the biggest selling point for me. Rather than relying on a single database, it can fall through multiple providers when the first source doesn’t have the contact, which makes a lot of sense because every data provider has its own coverage gaps. You end up with a much better chance of filling in missing email, phone or company data without having to manually check several different platforms.

I can take a list I already have, enrich it, verify the results, and get useful contact information without turning the process into a project. I also like that the enrichment isn't just about finding an email. You can fill in the broader contact and company record, which makes the resulting list much more useful for actual prospecting and CRM work.

It’s not perfect, and there are still some UX areas that could be polished, but the core product works well and the data quality has been better than I expected. It’s one of those tools that can quietly save a lot of time when prospecting.

Excellent product! I found the setup process to be quick and easy after a slight learning curve, which was not that difficult. You are able to perform general prepared searches, or perform a customized search similar to a LinkedIn advanced search. I was able to locate two old friends of mine as I knew their location area, which provided their phone number and email addresses. The amount of credits used is kind of high, but I do not perform many searches per day. I will probably upgrade to the next level for more monthly credits. I highly recommend this product.

Cleanlist is a strong choice for sales teams that need accurate, CRM-ready contact data without managing several separate tools. It combines waterfall enrichment, real-time email verification, phone-number discovery, deduplication, and AI-assisted research in one workflow.

Compared with ZoomInfo, Cleanlist is generally more flexible for enriching existing lists and avoids typical seat-based pricing. Compared with Apollo, it is more focused on data quality and enrichment than being an all-in-one prospecting database and outreach platform. And compared with standalone verification tools such as NeverBounce, Cleanlist goes further by enriching records, finding missing details, scoring leads, and syncing results to CRMs.

Its strongest advantage is the ability to return verified data from multiple providers and only charge for successful results. It is best suited to GTM, RevOps, and outbound teams that want cleaner records, fewer bounced emails, and less manual research.
