An agentic marketing platform works a bit like a dishwasher. You still load it and you still put the plates away, but the messy part in the middle runs while you do something else, and a good one doesn't need you standing at the sink to check on it.
This list covers five agentic marketing platforms, each built around a different kind of marketing work. We built Contengi, so it goes first, and each of the others is a strong pick for something we don't do. The rest are in no specific order.

1. Contengi: best for when you want content agents that write in your voice
Contengi, the agentic content platform we built, runs agents for SEO blogs, social posts, newsletters, press releases, opinion articles, and YouTube packages, all reading the same brand knowledge base of strategy, tone of voice, and hard rules. A hard-rule linter checks every draft, and blogs publish to WordPress, Shopify, Webflow, Framer, or a site built with Claude or v0, with updates going back to the same URL.
Automations and workflows let you describe a recurring job in plain English, run it on a schedule, and add approval gates where you want a say. The platform also reads Search Console, plans updates to live posts, and tracks mentions across five AI engines. Pricing is from $50 a month with no seats, plus your own Anthropic key, and it's in beta with strategist setup included.
What it doesn't do: Contengi has no CRM, doesn't run ads, and doesn't send email, so newsletters leave the send button to you.
Choose it if: content is your main growth channel and you want agents that research, write, and publish it without sounding like a robot.
2. HubSpot: best for when you want agents working inside your CRM
HubSpot's Breeze agents sit inside Marketing Hub, next to your contacts and campaign data. The Content Agent creates blog posts, social content, and landing pages grounded in your brand voice and audience data, the Campaign Agent plans a campaign from a goal, and the Nurture Agent rewrites each nurture email for the contact receiving it.
Marketing Hub has a free plan, and paid tiers are priced per seat, with a limited-time discount on Starter for new customers. The agent builder is included in Starter, Professional, and Enterprise, and custom agents use HubSpot credits.
Choose it if: your customer data already lives in HubSpot and you want agents that act on it directly.
3. Jasper: best for when you want a ready library of marketing agents
Jasper offers more than 100 specialised marketing agents, including a research agent that writes cited reports, an SEO and AEO rewriter, campaign brief and landing page agents, and a translation agent that covers 27 languages with glossary enforcement.
Jasper Pro costs $59 a month per seat billed yearly, or $69 billed monthly, with two brand voices, five knowledge assets, and three audiences, plus a seven-day free trial. Agents run on credits, and Business plans are custom priced on a 12-month commitment.
Choose it if: you run a marketing team with lots of campaign formats and want a pre-built agent for each one.
4. Zapier Agents: best for when the work spans lots of apps
Zapier Agents connect to your business data and carry out tasks across thousands of apps, on command or on a schedule. Templates include a lead enrichment agent that researches new leads, a sales email writer, and a content agent that researches trends and scripts videos.
The free Agents plan covers up to 400 activities a month, and Agents Pro costs $33.33 a month, billed annually at $400 a year, for up to 1,500 activities a month.
Choose it if: your marketing admin is scattered across forms, sheets, and inboxes and you want one agent tidying it up.
5. Relevance AI: best for when you want to build your own agent team
Relevance AI lets you build agents for specific marketing roles. Its marketing templates include an MQL qualifier, a lifecycle marketer for nurture campaigns, a content repurposer, and an SEO brief writer, and you shape each one around your own process.
Pro costs $19 a month billed annually, or $29 monthly, with 2,500 actions a month. The free plan is retired for new signups, so budget for Pro from day one.
Choose it if: you like building systems and want agents designed around exactly how your team works.
How to start with agentic marketing on a small team
- Pick one repeatable job. A weekly blog, a lead follow-up, or a monthly report each make a good first agent, and a vague "do my marketing" brief never does.
- Write the rules down first. Agents copy whatever you feed them, so set up your tone of voice and hard rules before the first run, the way you would maintain brand voice with AI for a person.
- Start simple. The simplest solution that works is usually the right one, and complexity only earns its place when a simpler setup fails.
- Add an approval gate. Anything that reaches a customer, a post, an email, or a reply, go past a person first.
- Borrow a proven workflow. Copy one of these agentic workflow examples instead of designing from scratch.
- Check the output for AI tells. Run a sample through the AI slop cleaner every week, since an agent that drifts does it slowly.
