Since telemarketing involves reaching out to prospects or customers through outbound calling, telemarketing software should offer automated dialing capabilities along with features like lead scoring, intelligent lead distribution, local caller ID, number reputation management, automated voicemail drop, and DNC list filtering to ensure compliance. Additionally, features like lead management, real-time call monitoring, call recording, and reporting are equally essential. You may also want to make sure the telemarketing software can be integrated with your CRM system to give your team a unified view of customer interactions.
