How many prospects should I have in my list?

Quality matters more than quantity. Most SDRs are most effective with 200-500 well-enriched prospects per month, allowing for personalized multi-touch outreach. If you're sending generic emails to 10,000 contacts, you'll get worse results than targeted outreach to 500 ICP-matched prospects.

What data do I need for effective prospecting?

At minimum: verified email address, job title, company name, and company size. For best results, also include: direct phone number, LinkedIn URL, industry, tech stack, and any relevant intent signals. The more complete the data, the more personalized and effective your outreach.

How do I keep my prospect data fresh?

Re-verify email addresses before each campaign, re-enrich contacts quarterly to catch job changes, and remove prospects who have bounced or explicitly opted out. Set up automated enrichment for new prospects entering your pipeline to maintain quality from day one.
