FAQ

What matters most before buying an AI outreach tool?

Confirm data quality, deliverability practices, CRM fit, compliance requirements, and whether the team can write a clear ICP.

Can AI personalize sales emails at scale?

Yes, but only when enrichment data is reliable. Bad account data creates shallow personalization and can hurt reply rates.
