Cold email automation that gets replies
ProspectHalo automates cold email end to end: it finds prospects, writes personalized emails, verifies deliverability, follows up, and books meetings, alongside LinkedIn in one agent.
Updated July 2026
Cold email still works, but only with verified lists, sharp personalization, strong deliverability, and disciplined follow-up. Doing all of that by hand is a full-time job. ProspectHalo automates the entire motion with an AI agent.
It is not just a sender. ProspectHalo finds the right people, writes each email for them, protects deliverability, and follows up, then hands you booked meetings, not a spreadsheet of sends.
Personalized, not templated
Each email is written from the prospect's real context, so it reads like a one-to-one message.
Deliverability protected
Contacts are verified and sending is paced to keep you out of spam.
Follow-ups that add value
Each follow-up brings a new angle, not a generic 'just bumping this'.
Multichannel
Email runs alongside LinkedIn in one agent, with a single reply inbox.
Deliverability comes first
The best-written email is worthless in spam. ProspectHalo verifies contacts before sending and paces volume to protect your domain reputation, so your emails actually reach the inbox.
Follow-up is where replies come from
Most replies arrive on the second or third touch. ProspectHalo runs the follow-up sequence automatically, varies the angle each time, and stops instantly when someone responds, so nobody gets a follow-up after they have already replied.
