The best ContactOut alternative is the one that finds the most verifiable contacts on your own prospect list. Contact finders differ mainly in method: stored databases, checks made at the moment you ask, chains of data providers, and LinkedIn browser extensions. Here are eight finders, unranked and grouped by how they work.
Contact finders look alike on the surface, but they don't get their data the same way, and that's what decides how many of your prospects they'll find.
ContactOut finds work and personal emails and phone numbers for outreach. The tools below do similar jobs with different methods: some search a stored database, some check contacts at the moment you ask, some query a chain of providers, and several work inside LinkedIn as a browser extension. They're in no particular order. These tools handle personal data, so the rules on how you use what they find matter as much as the tool itself.
Stored database, live check or waterfall?
Wiza says it verifies contact data at the moment you request it, rather than relying on a pre-loaded database. FullEnrich says it combines more than twenty providers in sequence, a method often called waterfall enrichment: if the first source has nothing, the next one is tried, and so on down the chain.
Neither method is automatically better. A live check may be fresher; a waterfall may find more. A stored database is quick but only as current as its last refresh. The only fair test is your own list, which is why the advice at the end of this page starts there.
Eight contact finders in one table
| Tool | Method | Good for |
|---|---|---|
| Dropcontact | Email finder and enrichment | Getting emails from a name and website |
| Evaboot | Sales Navigator export extension | Turning Sales Navigator searches into clean lists |
| FullEnrich | Waterfall enrichment | Checking many data vendors in one pass |
| Kaspr | LinkedIn extension and web app | Prospecting European contacts from LinkedIn |
| LeadIQ | B2B prospecting platform | Following champions when they change jobs |
| Skrapp | Email finder and verifier | Building lead lists from LinkedIn |
| Voila Norbert | Email finder | Lead research, PR and recruiting |
| Wiza | Prospecting with live verification | Checking contacts at the moment you ask |
Extensions that work inside LinkedIn
Kaspr works through a LinkedIn Chrome extension and web app, and the vendor stresses European profiles. Skrapp combines an email finder, a verifier and a Chrome extension for building lead lists from LinkedIn. Evaboot is built for Sales Navigator: it exports your search to a CSV and looks for verified emails along the way.
Extensions are quick to start with, but check LinkedIn's own terms for what's allowed on your account before one becomes part of your daily routine.
Finders that start from a name
Dropcontact says a first name, last name and company website are enough to return a verified email, and positions itself as GDPR compliant. Voila Norbert is a plain email finder aimed at lead research, recruiting, PR and HR, useful if you don't need a full platform and want something your whole team can pick up in minutes.
A full prospecting platform
LeadIQ goes beyond finding contacts, with buying signals, personalised outreach and a power dialer. Its job-change tracking is the feature to look at: the vendor says it follows your champions when they move companies so you can reconnect quickly.

Check the rules before you send
Rules on contacting people by email or phone, and on storing their details, vary by country and by whether you're contacting a business or a person. Check the regulator in the countries you target, or ask an adviser, before you load a list into a sequence. A vendor's compliance claim covers how it collects data; how you use that data is still your responsibility.
Contact finder tools, A to Z
Dropcontact
Best for: Teams enriching lists from a first name, last name and company website, from a vendor that positions its email finding as GDPR compliant.
Evaboot
Best for: Sales Navigator users who want lists exported to CSV with verified emails, in what the vendor calls a one-click move to a clean list.
FullEnrich
Best for: Teams that want emails and phone numbers found by querying many data vendors in sequence, which the vendor says draws on more than twenty premium sources.
Kaspr
Best for: Sellers prospecting on LinkedIn who want B2B contact data through a Chrome extension and web app, with the vendor stressing European profiles and compliance.
LeadIQ
Best for: Sales teams that want prospect data, buying signals, personalised outreach and a power dialer together, plus alerts when champions change jobs, per the vendor.

Wiza
Best for: Prospectors who want verified emails and phone numbers from filtered searches, with the vendor saying it checks data on request instead of using a pre-loaded database.
My advice for picking a contact finder
Run the same real list through two or three tools before you commit. Take a few dozen prospects you'd contact anyway, run them through each tool, and count only the emails and numbers you can verify, not the ones a tool shows. Then compare what each tool found that the others didn't. That overlap tells you whether one tool is enough or whether a second one earns its place.
Match the tool to how you work, too. If you live in Sales Navigator, an extension saves clicks. If your lists arrive as spreadsheets, a finder that starts from a name and company website will fit better. And if your team runs calls as well as email, a platform with a dialer saves switching between tabs.

Frequently asked questions
What is waterfall enrichment?
It's when a tool asks several data providers in turn for a contact, moving to the next one when the first has nothing. One tool in this list says it works that way.
Do contact finders give personal emails?
Some say they find personal as well as work details. Check whether you're allowed to use personal contact details for outreach in the countries you target.
Are LinkedIn extensions allowed?
Check LinkedIn's own terms and each extension's documentation before you rely on one for daily prospecting.
How do I test a contact finder's accuracy?
Run the same list of real prospects through each tool and verify the results, for example by sending to a small sample and watching for bounces.
Does a GDPR claim cover my outreach?
No. A vendor's claim covers how it collects data. Your own use still has to meet the rules where you and your prospects are, so check with the regulator or an adviser.
Is this list of contact finders ranked?
No. The tools are in no particular order and grouped by how they find contact data.
