How Warmerly does it
Warmerly, in detail.
Companies from Warmerly's own database found by sentence or filter, an email finder, an email verifier with monthly allowances by plan, and a LinkedIn people search that needs a connected account.
01
Search a company database in plain words
Lead finder turns a sentence such as 'dental practices in the UK' into filters, shows the matching companies, and lets you export a CSV or add them to a campaign. Searching is free. Only exporting and adding leads to a campaign use your monthly lead allowance. The AI step never touches the database: it only produces filters.

02
An email finder
Email finder takes a company website, domain or LinkedIn URL, or a person's name plus their company. It shows the address with a status, a confidence score and how it was found. A lookup counts against the monthly allowance only when an address is actually found.

03
An email verifier
Email verification checks one address or a bulk list and answers Safe to send, Send with caution, Do not send or Unknown, with a confidence score and a plain reason. A standard check does not send a message to the address.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Check the price per found address
Dux-Soup's credit price is not on the pages we read, and Warmerly's allowances are written into each plan.
Verification matters before you send email
Warmerly's verifier answers Safe to send, Send with caution, Do not send or Unknown.
LinkedIn-only outreach may not need a database
If you reach people through LinkedIn search, the lookup may be enough.
Building a list of 500 dentists
On Warmerly you search the company database in plain words for free, and exporting or adding 500 leads uses 500 of Starter's 500 monthly lead exports, or 5,000 on Growth. On Dux-Soup you need LinkedIn profiles of those dentists first.
Finding 300 emails
Warmerly's Starter plan allows 1,000 lookups a month, and a lookup counts only if an address is found. On Dux-Soup 300 found emails mean 300 credits, bought in the STACKED Store at a price its article does not state.
Cleaning a bought list
Warmerly's verifier answers safe to send, send with caution, do not send or unknown for a list, 5,000 a month on Starter. Dux-Soup lists no verifier.
Moving prospects between tools
Dux-Soup exports prospects to CSV or a CRM. Warmerly imports a CSV with an Email column, so only prospects with an email carry over.
