- Compliance: If you operate in the EU/EEA or care about auditability, look for source tracking, suppression lists, approval-first sending, and clear documentation (e.g. GDPR, ePrivacy).
- Outreach vs. database-only: Some tools focus on contact data; others add email sequences, follow-ups, and reporting. Match the product to your workflow.
- CRM integration: Check that your CRM is supported and whether sync is included at your plan level.
- Cost per lead and TCO: Compare listed price, lead limits, and cost per lead (and per qualified lead) over 6–12 months.
