ProspectRoom vs Instantly
Instantly is best for teams doing pure high-volume cold email. ProspectRoom is best for teams where every touch needs to convert at a higher rate.
What each tool does
Instantly.ai is a cold email platform optimised for sending at scale. It offers unlimited email sending across multiple connected accounts, a large email warmup network that rotates sends across domains to maintain deliverability, built-in sequencing, and A/B testing. It is primarily used by agencies, lead generation operators, and high-volume outbound teams who measure success by reply count.
ProspectRoom takes the opposite approach to volume. Rather than sending thousands of emails per day, you send a smaller number of short messages with links to fully personalised rooms. Each room opens with the prospect's name and includes an AI agent that handles the full conversation. The strategy is quality per touch, not total volume.

Which one to choose for your situation

Some teams use Instantly for broad top-of-funnel email outreach and send ProspectRoom rooms to prospects who open an Instantly email but do not reply. This second-touch strategy uses Instantly's volume for initial reach and ProspectRoom's conversion for warm follow-up.
