Cost-Effective: Once set up, AI SDRs eliminate ongoing salary expenses, reducing the cost per lead.
Consistent Messaging: AI ensures every prospect receives uniform, high-quality communication.

Challenges of AI SDRs

Limited Relationship Building: AI cannot replicate the human touch required for building deep relationships.
Dependence on Data: AI performance is contingent on the quality and accuracy of the data it processes.
