Start with who you are not selling to
Most lead lists fail because they start too broad. Before you pull a single contact, write down the companies and roles that have never become good customers. Excluding them early makes every later step cheaper. A tight exclusion list also gives your team a shared sense of what a bad lead looks like, which makes qualification faster and less subjective.
Define your ideal customer
- Industry and sub-industry
- Company size and growth stage
- Region and time zone
- The roles that actually sign off on a purchase
Verify before you reach out
An unverified email is a cost, not an asset. Bounces damage your sender reputation and waste a rep's attention. Verify every contact, and re-verify lists that are more than a few months old.
