Best Practices for Prospecting

1. Layer Your Tools

Don't rely on a single source. Use multiple tools:

Example stack:

• Apollo.io for initial prospect lists
• LinkedIn Sales Navigator for research and warm intros
• Hunter.io to verify/find emails
• Clearbit to enrich data

2. Verify Before Outreach

Always verify contact data before adding to sequences:

• Bounce rates over 2% hurt deliverability
• Invalid phone numbers waste time
• Old job titles reduce relevance

3. Enrich Your Data

Add context to improve personalization:

• Recent company news
• Technologies they use
• Hiring activity
• Funding rounds

4. Keep Data Fresh

Contacts change jobs, companies change focus:

• Re-verify data every 90 days
• Remove bounced emails immediately
• Update job titles quarterly
• Check company changes monthly

5. Respect Privacy

Follow data privacy regulations:

• Honor unsubscribe requests
• Don't spam
• Have legitimate business interest
• Provide opt-out mechanisms
