Who needs an AI agent for campaigns?
Any team that repeats the same 5 campaign jobs, from audience to report, on every campaign can hand part of the work to an agent. An AI agent is software that takes steps on its own, such as drafting an email or picking who gets it, instead of waiting for a click.
It covers marketing tools only. If you sell to a short list of target companies, see AI agents for account-based marketing. For outbound sales messages, see AI SDR tools for outbound sales.
Which jobs can an AI agent take over in a campaign?
An AI agent can take over 5 campaign jobs, and each of the 6 tools here does at least one of them.
| Job | What the agent does | Tools with an agent or AI feature for it |
|---|---|---|
| Build the audience | Finds or groups the people to reach | HubSpot, ActiveCampaign, Klaviyo, Brevo |
| Write the content | Drafts emails, posts and landing pages in your brand voice | HubSpot, ActiveCampaign, Brevo, Klaviyo, Salesforce, Zapier |
| Launch the campaign | Builds the campaign and sends it, on email and, in HubSpot, on LinkedIn and Meta ads | HubSpot, Klaviyo, Salesforce, ActiveCampaign, Brevo |
| Test | Compares versions and picks the send time | Klaviyo, Brevo, ActiveCampaign, Salesforce |
| Report | Explains what worked and what to do next | Klaviyo, HubSpot, Salesforce, ActiveCampaign, Brevo |
Agents differ in how much they do alone, so check who approves each step before anything goes to your list.
Which AI agents help build the campaign audience?
Four of the 6 tools have an agent or AI feature that builds or sharpens the audience: ActiveCampaign, Klaviyo, Brevo and HubSpot.
| Tool | What the agent or AI feature does | Where it sits |
|---|---|---|
| ActiveCampaign | Suggests segments from your contacts, and its AI campaign builder starts from them | All plans |
| Klaviyo | Builds segments with generative AI, and Composer can create a segment from a plain request | Email plan and up; Composer |
| Brevo | Aura AI suggests audience groups from behavior and attributes | Professional plan, $499 a month |
| HubSpot | Audience Segments find and target anonymous website visitors by fit and intent, and Lookalike Lists find people like your best customers | Marketing Hub |
A segment is a group of contacts who share something, such as a purchase or a page they visited. Start with the segment that already buys from you, then let the agent suggest the next group to test.
Which AI agents help write the campaign content?
All 6 tools can draft campaign content, from email copy to blog posts.
| Tool | What the agent or AI feature does | Where it sits |
|---|---|---|
| HubSpot | The Content Agent (beta) writes blog posts, LinkedIn content and landing pages after it researches competitors and keywords | Marketing Hub |
| ActiveCampaign | Generative AI writes email copy and images, and a Brand Kit holds your voice | Plus plan and up |
| Salesforce | The Campaign Agent creates on-brand, channel-ready content from your brand guidelines | Growth edition (agentic content) and up |
| Brevo | An AI content generator drafts subject lines and email copy and changes the tone | Starter plan and up |
| Klaviyo | Composer drafts campaigns and flows, and builds email and SMS for one campaign from a single description | Composer |
| Zapier | Zapier Agents run a marketing template that creates researched, scripted content in a document | Zapier Agents |
Brand voice matters more than speed here. Give the agent three of your best past emails or posts before the first draft, and read every draft before it goes out.
Which AI agents help launch a campaign?
Five of the 6 tools help launch a campaign. All five send email, and HubSpot also manages ads on LinkedIn and Meta.
| Tool | What the agent or AI feature does | Where it sits |
|---|---|---|
| HubSpot | Manages ads on LinkedIn, Meta, Google, TikTok and more in one place, and its Social Media Management tool posts and answers across social channels | Marketing Hub; the ads tool is free |
| Klaviyo | Builds and sends email and SMS campaigns in one conversation, and Meta Ads in Composer lets you see which Meta ads bring customers back | Composer |
| Salesforce | Agentic campaigns build a campaign for every channel from a goal and guardrails and adjust as it sends; conversational email, RCS, SMS and WhatsApp are on the same edition | Advanced edition; Growth has multi-channel journeys |
| ActiveCampaign | Its AI automation builder and AI campaign builder set up the sends, and cross-channel marketing starts on Plus | All plans; cross-channel from Plus |
| Brevo | Runs unlimited multi-step automations from Standard, and adds WhatsApp, pop-ups and push messages on Professional | Standard and Professional plans |
Launching is where a mistake costs the most. Send the first version to a small test list, and keep a person in the loop for anything that goes to your whole list or spends ad money.
Which AI agents help test campaigns?
Four of the 6 tools run tests for you: Klaviyo, Brevo, ActiveCampaign and Salesforce.
| Tool | What the agent or AI feature does | Where it sits |
|---|---|---|
| Klaviyo | Composer sets up an A/B test across email and SMS in one conversation; A/B testing starts on the Email plan | Email plan and up |
| Brevo | A/B tests on subject lines or content, and AI send time optimization that sends when each contact is most likely to engage | Standard plan, $18 a month |
| ActiveCampaign | Predictive sending picks each contact's best time, and Active Intelligence keeps tests and reviews running in the background | Pro plan for predictive sending |
| Salesforce | Agentic campaigns optimize as they send, using customer intent signals, and AI-powered engagement scoring is on the same edition | Advanced edition |
An A/B test sends two versions of one message to two small groups and keeps the one that wins. Test one thing at a time, such as the subject line or the send time, so you know what changed the result.
Which AI agents help report on campaign results?
Five of the 6 tools turn campaign data into a report or a next step: Klaviyo, HubSpot, Salesforce, ActiveCampaign and Brevo.
| Tool | What the agent or AI feature does | Where it sits |
|---|---|---|
| Klaviyo | Composer analyzes your performance on request, runs scheduled reports and audits, and turns an answer into a dashboard you can share | Composer |
| HubSpot | Marketing Analytics, dashboards and, on advanced reporting, multi-touch attribution that links revenue to campaigns | Marketing Hub |
| Salesforce | AI Campaign Summaries explain results in the Marketing Intelligence add-on, and attribution reporting is in Growth | Growth edition; Marketing Intelligence add-on |
| ActiveCampaign | Active Intelligence sends a weekly review of what worked with one next step you can apply | Active Intelligence, with limits on every plan |
| Brevo | The AI Data Analyst answers plain-language questions about your data | Professional plan |
Ask for one report in the same format every week. A report that changes shape each time hides whether the numbers moved.

Which AI agent fits your team?
Team size and where your data lives decide the fit, and 5 kinds of team cover most cases.
A small team with a small budget
ActiveCampaign Starter is $15 a month billed yearly, Brevo is free or $9 a month, Klaviyo is free up to 250 profiles and Zapier Agents is free for 400 activities a month. Start with the free plan that matches your channel, and move up when you hit a limit.
An online store
Klaviyo is built for consumer brands and online stores, and Composer covers email, SMS, tests and reports in one place. Meta Ads in Composer lets you see which Meta ads bring customers back.
A B2B team that works in a CRM
HubSpot keeps the campaign, the contact record and the ad data in one system, so the agents use the same data you sell from. Check which agents are still in beta before you plan around them.
A team with tools spread across many apps
Zapier Agents work across more than 9,000 apps, so one agent can work in several of your tools. Agents Pro is $50 a month billed monthly. Pair it with one of the campaign platforms above.
A large team with governance needs
Salesforce Marketing Cloud Next starts at $1,500 a month per org and adds engagement scoring on Advanced. It suits teams that already run on Salesforce.
What should you check before you choose an AI campaign agent?
Check 5 things before you pay, because they decide the real cost.
- Which plan holds the agent? Predictive sending is on ActiveCampaign Pro, A/B tests and send-time tools are on Brevo Standard, and Salesforce has agentic content on Growth and agentic campaigns on Advanced.
- What counts as usage? HubSpot uses credits, Klaviyo gives $5 of Composer usage on the free plan, ActiveCampaign gives 500 AI credits on every plan and Zapier Agents count activities.
- Does the price rise with your list? ActiveCampaign, Klaviyo and Brevo set the price by contacts, profiles or emails, so price your list size, not the entry plan.
- Does the agent act or only suggest? Klaviyo's Composer drafts and you review. In Salesforce you set the goal and guardrails. Decide who approves before anything goes to your full list.
- Is the agent still in beta? HubSpot's campaign, content and nurture agents are in beta. Test them on a small list first.
Prices are as of 5 November 2026 and can change.
