What is ProspectHalo?

ProspectHalo is an AI sales-engagement platform. Describe your ideal customer in plain English to find the right prospects with verified contact details, then run one multichannel sequence across your own LinkedIn and email accounts, with AI personalizing every message, and manage every reply in one unified inbox. It brings prospecting and personalized follow-up into a single place.

Does ProspectHalo send the messages for me?

Yes. Connect your own LinkedIn and email accounts, pick a method (LinkedIn, email, or both together in one multichannel sequence), and AI writes a personalized message for every step. Messages send from your own accounts at a safe, randomized daily pace, and you can connect multiple accounts to spread the volume. Every reply lands in a unified inbox sorted by intent.

How does ProspectHalo personalize each message?

AI writes a unique message for every prospect using their role, company, and industry. Before reaching out, it checks the prospect's current role on LinkedIn so the message matches who they are today, not an outdated title, and skips anyone who no longer fits your target. On Pro, prospect research also lets AI read each prospect's company website and tailor the message to their actual business and likely pains. It only references details it can verify, so it never makes things up.

Can AI reply to prospects automatically?

Yes, with Autopilot (Pro). When a prospect replies, AI writes and sends the next reply from your own account, driving the conversation toward your goal and sharing your booking link to set up meetings. It only auto-replies to interested prospects, stops and hands off to you if someone is not interested or after a few replies, and you can take over any conversation in one click. Prefer to handle replies yourself? Leave Autopilot off and reply manually with AI draft help.

Is my account safe when sending messages?

ProspectHalo sends from your real profile through an official integration, caps each account at a conservative daily limit you control, and spaces messages with randomized gaps to respect platform limits. Connecting more accounts lets you send more without pushing any single account too hard.

Is this data accurate and up to date?

Profile and company data comes from verified business sources, then we check each prospect's current role against their live LinkedIn before reaching out, so an outdated title never ends up in a message. We also verify every email in real time right before it sends, so dead mailboxes get filtered out instead of bouncing from your account. Most addresses deliver cleanly, and any bounce is on us, not your reputation, and never counts against your limit.

What kind of contact data do you provide?

Business (B2B) contact details only: names, roles, companies, LinkedIn profiles, and work emails. Profile and company records come from verified business sources and are refreshed regularly, and every email is validated in real time before it sends. We do not sell consumer data.

How is ProspectHalo different from Apollo or ZoomInfo?

Traditional platforms make you learn their software to build a list, then move it into another tool to reach out. ProspectHalo does both in one place: describe who you want, get verified prospects, and send personalized LinkedIn and email messages from your own accounts, with replies in one inbox.

What happens when I hit my monthly limit?

Your plan pauses gracefully. You will not get surprise overage charges. Upgrade your plan in two clicks if you need more, or wait until your monthly reset on the 1st.

Is ProspectHalo GDPR compliant?

Yes. We only handle business (B2B) information: names, work emails, roles, and companies. We do not sell consumer data. You are responsible for following GDPR, CAN-SPAM, and CCPA when you contact anyone.

Can I cancel anytime?

Yes. Two clicks in the billing page. No guilt screens. No retention calls. Your data exports stay yours after you cancel.

What counts as one contact?

One complete contact record: name, work email, phone, role, and company details. If we return zero contacts for a search you pay zero. Bounced emails do not count against your limit.
