Hunter.io is a popular, well-built email finder. Its domain search and email verifier are fast and simple, and for email-only outreach it does the job. But Hunter is focused on email addresses. If your outbound motion includes cold calling, WhatsApp follow-ups or SMS, you need a tool that returns direct dial and mobile numbers alongside verified emails.
This guide compares Hunter.io alternatives that find both emails and phone numbers, explains what to look for, and helps you pick the one that fits the way your team actually prospects.
Short answer
If you want a Hunter.io alternative that also finds phone numbers, look at tools that combine an email finder with a phone database and a LinkedIn Chrome extension: Apollo, Lusha, Kaspr, ContactOut, RocketReach, SignalHire and PeakAI are the most common options. The right choice depends on the regions you sell into, whether you need a full sales platform or just contact data, and how the credit model works for your volume.
What to look for in a Hunter.io alternative with phone numbers
- Phone type: Does the tool return direct dials and mobile numbers, or mostly company switchboard numbers? Direct dials are what make cold calling productive.
- Regional coverage: Data depth varies a lot by country. A tool that is strong in the US may be thinner in Europe or India, and vice versa. Test with contacts from your real target market.
- Email verification: You still want verified emails to protect your sender reputation, so the tool should validate addresses, not just guess patterns.
- Workflow: A LinkedIn Chrome extension, bulk enrichment from CSV, and CRM integrations (HubSpot, Salesforce, Pipedrive) save hours compared with copy-pasting.
- Credit model: Many tools charge separate credits for emails and phone numbers, and phone credits are often more expensive. Check current pricing on each vendor's site and work out cost per usable contact, not cost per credit.
- Compliance: Look for clear GDPR and opt-out handling, and if you sell in India, awareness of the DPDP Act.
The alternatives
1. Apollo
Apollo is an all-in-one sales platform: a large B2B database, email sequencing, a dialer and a Chrome extension. It returns both emails and phone numbers. It suits teams that want prospecting and outreach in one place. If you only need contact data, you may end up paying for features you do not use, and phone number reveals are typically limited by plan. Check current pricing on Apollo's site.
2. Lusha
Lusha is known for its simple Chrome extension that shows emails and phone numbers on LinkedIn profiles and company websites. It is easy to roll out to a sales team and integrates with major CRMs. Coverage is generally strongest in North America and parts of Europe. Phone numbers consume more credits than emails, so model your usage before committing.
3. Kaspr
Kaspr is a LinkedIn-focused Chrome extension with a strong reputation for European phone data. It is a good fit for SDR teams prospecting into Europe who mainly work from LinkedIn. It is lighter on extras than a full platform, which many users see as a plus.
4. ContactOut
ContactOut is popular with recruiters and sales teams for finding personal and work emails plus phone numbers from LinkedIn profiles. It works well for candidate sourcing as well as sales. Check how it labels personal versus work contact details, and use them in line with your compliance policy.
5. RocketReach
RocketReach offers a large searchable database of professionals with emails and phone numbers, plus an API and bulk lookups. It suits teams that search by company, title and location rather than working profile by profile on LinkedIn.
6. SignalHire
SignalHire provides emails and phone numbers via a Chrome extension, web search and API, and is used by both recruiters and sales teams. It is a flexible option if you want pay-as-you-go style usage. As with any vendor, test match rates on your own target list.
7. PeakAI
PeakAI (thepeakai.com) is a focused B2B contact-data tool rather than a full sales platform. It finds verified emails and phone numbers, works on LinkedIn through a Chrome extension, and can enrich existing CRM records with missing contact details. It is worth considering if you want contact data without paying for a sequencing suite, and especially if you prospect into India, where many global databases are thinner. Like every option here, run a trial on a sample of your real prospects before deciding.
