Voice, native
Lead Gen & CRM has no native calling; call data comes through a paid CallRail integration. Mercury's AI voice agents answer every call, qualify, and book 24/7.
Mercury vs SharpSpring
SharpSpring, now Lead Gen & CRM by Constant Contact, automates marketing without the phones. Mercury adds AI voice, a dialer, and dispatch.
