Editorial Face-off

The Case for Buzz

Buzz offers a compelling multichannel approach to sales engagement. The combination of LinkedIn, email, and phone in one sequence builder is its key differentiator. However, limited pricing transparency and a smaller ecosystem compared to established players like Outreach may give some teams pause.

The Case for Reply.io

Reply.io is one of the most complete multichannel outreach platforms available. Its AI SDR and built-in data make it excellent for teams wanting everything in one place. Best suited for SMB sales teams and agencies.
