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.
