Robust buying signals with reliable contact data
Amplemarket
Duo, Amplemarket’s AI sales copilot, tracks multiple signals from diverse sources and delivers a frequently refreshed database with over 70 million updates every few weeks. Duo ensures accurate and comprehensive contact information, so no leads are missed.
Common Room
Surfaces many signals but struggles with contact data. Applying filters like "primary email" drastically reduces usable contacts, excluding over 70% of leads. This requires users to integrate more data sources, increasing costs and complexity.
Multichannel sequences with intent-based hooks
Amplemarket
Duo automatically generates complete multichannel sequences with personalized hooks, such as company news, job changes, or social activities. Duo enables outreach across email, social media, and creative channels like voice and video messages.
Common Room
Roomie AI creates only first-touch emails, requiring manual edits and external tools (like Outreach or Salesloft) to run campaigns. Its single-channel focus limits outreach flexibility.
Automated social prospecting and outreach
Amplemarket
Automates lead sourcing and outreach from social platforms, including voice and video messages, for a creative and efficient approach to prospecting.
Common Room
Offers social outreach plays. Unlike Duo, signal sourcing is manual, and execution requires additional tools; adding unnecessary effort.
Advanced deliverability solutions
Amplemarket
Ensures high deliverability with features like multi-domain/mailbox support, inbox placement tests, warmups, and mailbox rotation.
Common Room
Lacks deliverability solutions, restricting users to data and signals without ensuring their outreach reaches the right inbox.
“Amplemarket has made the task of gaining trust with our prospects that much easier with its AI Copilot.”
