How to validate B2B contacts before sending?
- Validating B2B contacts before sending reduces waste, protects reputation, and improves targeting.
- Technical validation:
- Run addresses through verification services
- Check for syntax errors and typos
- Identify catch-all domains (delivery uncertain)
- Flag disposable or temporary email providers
- Data quality checks:
- Verify the company still exists and is active
- Confirm the person still works there (LinkedIn, company website)
- Check that their role matches your targeting criteria
- Assess data age (when was this record created or updated?)
- Relevance validation:
- Does this person's role relate to what you're offering?
- Is this company in your target market?
- Are there signals suggesting interest or need?
- Suppression checks:
- Compare against your unsubscribe list
- Check for previous bounces or complaints
- Verify against any global suppression lists you maintain
- Validation takes time but prevents sending to people who can't, won't, or shouldn't receive your messages.
