Cold email at scale, without the busywork
Scale cold email without hiring or babysitting tools. ProspectHalo finds prospects, personalizes emails, protects deliverability, follows up, and books meetings.
Updated July 2026
Scaling cold email usually means more tools, more mailboxes, and more manual work, or hiring someone to run it. ProspectHalo lets you scale the outcomes without scaling the busywork, because an AI agent does the finding, writing, sending, and following up.
You keep control of your offer and targeting; the agent handles execution and deliverability, and pairs email with LinkedIn so you are not limited to one channel.
No manual list-building
The agent finds and verifies ICP-matched prospects for you.
Personalized at scale
Every email is written for the recipient, even across large volumes.
Inbox placement
Verification and paced sending protect your domain reputation.
Follow-up handled
Multi-step follow-ups run automatically and stop on reply.
Scale outcomes, not headcount
The point of automation is more meetings without more people or more hours. ProspectHalo runs the full cold-email motion so a founder or a lean team can operate at a volume that would otherwise require an SDR, while keeping quality high.
