Compared with HubSpot’s marketing agents
HubSpot’s marketing agents plan, draft and personalize your campaigns inside the CRM, where your contacts and deals already are. None of the agents HubSpot lists runs your paid ads.
What it does well
HubSpot’s agents work on the whole CRM: a campaign is planned from your contacts, deals and past results, and reported on attributed revenue and deal influence. For a B2B team already in HubSpot, its campaign, content and nurture agents are a strong start.
- Planning campaigns from your CRM: contacts, deals and past performance.
- Reporting attributed revenue, ROI and deal influence.
- Drafting content, landing pages and nurture emails in HubSpot.
- Personalizing automated emails for the share of recipients you choose, half by default.
Where it stops
- 1None of the agents HubSpot lists runs paid ads. In HubSpot you edit budgets and bids yourself, with AI to draft ad copy and Google’s recommendations to apply.
- 2The campaign agent plans and drafts; you review, approve and publish each asset.
- 3Its nurture agent is set email by email: locked text, the CRM data it reads, the share of recipients who get a personalized version, and a monthly credit cap.
Side by side, with cost.
| Question | HubSpot’s marketing agents | Heraldic |
|---|---|---|
| What it runs | Campaign plans, content and nurture email in HubSpot; none of its listed agents runs paid ads | Paid ads and lifecycle email, with an agent for each job |
| Who acts | Its marketing agents plan and draft for you to publish; the nurture agent personalizes sends once on | Agents propose; for each kind of action, you choose whether it waits for you |
| Your limits | Set email by email for the nurture agent: locked text, data sources, share of recipients, credit cap | Daily spend caps, a 20% limit on each change, and contact and content rules, checked before every change; no raise once the month’s cap is reached |
| Judged on | Attributed revenue, ROI and deal influence in your CRM | Your conversion events, each valued by what it’s worth to you |
| The record | Previews show why it changed the text; sent versions viewable for 30 days | Every action, with who proposed it, why, the checks it passed and who approved it |
| Creative | Drafts content, emails and ad copy | Images and copy drafted from your approved library; none runs until it’s approved |
| What it costs | HubSpot Credits, $10 per 1,000; Marketing Studio needs Marketing Hub Pro or Enterprise. | Not set yet. Ad spend goes straight to the ad platforms |
When to choose it instead
If you’re a B2B team in HubSpot that wants help planning and drafting campaigns, and someone else runs your paid ads. If you want ads and email run every day under one set of rules, judged on your pipeline, that’s what agents here do.
Questions about this comparison
Can agents judge on closed deals instead of form fills?
Yes. Send stages such as qualified lead and signed contract as conversion events, from your CRM or the events API, and agents judge on them, each valued by what it’s worth to you.
What do agents do that HubSpot’s don’t?
Run your paid ads alongside your email. Agents propose budget, bid, pause and launch changes and email sends, under spend caps, change limits and contact rules, and every action is logged in one place.
What about a long sales cycle?
Until closed deals arrive in numbers, agents steer by earlier steps, like qualified leads, and act less often. When there isn’t enough evidence, the report says it’s too early to call.
