Voice, not just email
ActiveCampaign has no native calling or AI voice; both come from third-party apps. Mercury includes an AI front desk that answers every call 24/7, a full outbound dialer, and SMS follow-up.
Mercury vs ActiveCampaign
Email automation is not a phone system. Mercury adds the AI voice, dialer, and dispatch your follow-up is missing.
