What the Prospecting Agent Actually Does
HubSpot just gave every sales team an AI-powered SDR. It's called the Prospecting Agent, and it lives inside Breeze, HubSpot's AI engine.
Our team attended a HubSpot Expert event where they demoed the full setup. The short version: it researches prospects, writes personalized emails, and sends them at scale. All from inside your HubSpot workspace.
It's impressive. It's also dangerous if you set it up wrong.
Forget basic email sequences with merge tags. This agent does real research before it writes a single word.
It scans the web and your CRM for buying signals. New funding rounds, job changes, company news. Then it writes outreach emails that reference those specific details. Not "Hi {First_Name}, I noticed your company is growing." More like referencing the exact initiative a prospect just announced on LinkedIn.
The setup takes about 15 minutes. You create a Selling Profile by plugging in your website URL. The agent pulls your mission, value proposition, and the pain points you solve. You pick who the emails come from, set your CTA (meeting link, document, or custom URL), and configure your tone of voice.
You can run it in two modes: review before sending or fully automatic. Review mode shows you every draft before it hits an inbox. Automatic mode lets the agent run on its own.
The Speed Difference Is Real
Manual prospect research takes a rep 15 to 20 minutes per contact. The Prospecting Agent does it in under 60 seconds.
That means a rep who could research and email 20 prospects a day can now cover hundreds. The personalization quality stays high because the agent pulls real context, not just a name and company.
For teams running outbound at scale, the math is hard to ignore.
Here's the Problem Nobody Is Talking About
When our team brought this to me, my first response wasn't "let's turn it on." It was a warning.
The Prospecting Agent sends emails from your connected HubSpot inbox. For most companies, that means your core business domain. If you're grantbot.co, it sends from @grantbot.co.
This is a serious problem.
Cold outreach gets flagged as spam. That's just reality. Even well-written, personalized emails get marked by recipients who didn't ask to hear from you. When enough people flag your emails, email providers (Gmail, Outlook, Yahoo) start throttling your entire domain.
Once your core domain reputation tanks, every email from that domain suffers. Your invoices. Your client updates. Your team's internal communication with external partners. All of it lands in spam.
I've seen this firsthand. At a previous company, we ran outbound from the primary domain. People flagged the cold emails, and within weeks we couldn't reliably deliver any email from that domain. The company had to migrate everything to a new domain. That meant updating every system, every link, every piece of collateral. It cost months of work and real revenue.
What to Do Instead
Never run cold outbound from your core domain. Buy separate domains specifically for outreach.
Here's the setup that protects you:
Your core domain (yourcompany.com) stays clean. It handles client communication, transactional emails, and marketing to people who opted in. You purchase secondary domains (like yourcompany-outreach.com or tryyourcompany.com) and warm them up over 2 to 4 weeks before sending any volume.
Run the Prospecting Agent through those secondary domains. If one gets flagged, you rotate to another. Your core domain never takes a hit.
This is standard practice for any team doing outbound at scale. The fact that HubSpot's default setup points you toward your primary domain is a blind spot in the product.
The Credit System
HubSpot charges 100 credits per contact per month for the Prospecting Agent. Your credit allowance depends on your plan:
Starter plans get 500 monthly credits. Professional gets 3,000. Enterprise gets 5,000.
Before you turn it on, do the math. If you're enrolling 50 contacts at 100 credits each, that's 5,000 credits per month. That might eat your entire Enterprise allowance on a single agent.
Should You Use It?
Yes, but with guardrails.
The Prospecting Agent is a real upgrade over static sequences. The research quality is strong. The personalization is better than what most human reps produce under time pressure. And the speed advantage compounds fast.
But treat it like any powerful tool. Set it to review mode first. Run it through secondary domains. Monitor your email health metrics weekly. And don't let the ease of setup trick you into skipping the infrastructure that protects your business.
If your team is running outbound and you want to set up the Prospecting Agent the right way, with proper domain infrastructure and CRM configuration, book a strategy call with our team. We'll build it so your core domain stays untouched and your outbound actually lands in inboxes.
