1. Email Finding
Hunter IO： Domain Search returns all publicly available emails for any company website. Email Finder locates specific people by name and company. Both features pull from Hunter’s database of over 100 million indexed email addresses. Chrome extension works directly on LinkedIn profiles.
Mailshake： Data Finder searches for prospects by role, location, or company. The tool comes with limited free credits on each plan. Quality varies and doesn’t match dedicated prospecting platforms. Most teams bring their own lists rather than relying on Data Finder.
⚠️ Warning: Mailshake’s Data Finder is not its core strength. If email finding is your priority, Hunter IO is the clear winner here.
2. Email Verification
Hunter IO： Built-in Email Verifier checks deliverability before you send. Uses 0.5 credits per verification. Returns status as valid, invalid, accept-all, or unknown. Bulk verification available through the dashboard and Google Sheets add-on.
Mailshake： Includes basic email verification as part of list cleaning. Checks addresses before sending campaigns. Not as detailed as dedicated verification tools. Works best for cleaning imported lists rather than bulk verification projects.
3. Cold Email Campaigns
Hunter IO： Campaigns tool sends email sequences through your connected Gmail or Outlook account. Supports basic personalization and follow-ups. Limited to 2,500-15,000 recipients depending on plan. Best for simple outreach rather than complex sequences.

⚠️ Warning: Hunter IO’s campaign features are basic. If cold email is your main use case, Mailshake offers far more automation and control.

Mailshake： Send LinkedIn connection requests and messages as part of your sequences. Profile views add another touchpoint. Automation runs in the background while you focus on replies. Available on higher-tier plans only.
5. Phone Dialer
Hunter IO： No phone dialer or calling features. Hunter IO focuses entirely on email finding and verification. You need a separate tool if phone outreach is part of your sales process.

6. Email Deliverability
Hunter IO： No built-in email warmup or deliverability tools. Relies on your email provider’s sending limits. Verification helps reduce bounces, but you need separate warmup if sending cold emails at scale.

7. 浏览器扩展程序
Hunter IO： Chrome extension finds emails while you browse any website. Works on company sites, LinkedIn profiles, and anywhere else you research prospects. Save leads directly to your Hunter account with one click.

8. 集成
