- Extensive integrations with major CRMs (HubSpot, Salesforce, Pipedrive, Zoho) and 5,000+ apps via Zapier
- Transparent email sourcing showing where each address was found on the public web
Cons
- Credit-based system means heavy users can burn through allowances quickly, especially on lower tiers

Cons
- Pricing is split across three separate products (Sending, Leads, CRM) — full functionality requires multiple subscriptions
- Entry-level sending plan limits contacts to 1,000 and emails to 5,000/month, which is restrictive for active outreach
- Primarily focused on email outreach — multi-channel capabilities (calling, SMS) are limited to higher CRM tiers
- Credit-based lead database pricing can be confusing with variable ranges (e.g., 1,500-2,000 credits)
