How to choose an AI marketing agency that gets results you can check

What is an AI marketing agency?

An AI marketing agency is a marketing company that uses AI tools as a core part of its work. It still does the usual jobs of an agency, such as content, ads, email and social media. The difference is that AI does much of the drafting, testing and reporting, and people direct and check it.

These agencies tend to fall into two groups:

• Campaign agencies: They run your marketing for you and use AI to make content and ads faster.
• Automation agencies: They build systems that run your marketing tasks on their own, such as lead follow-up, chatbots and email flows.

Many agencies offer some of both. Ask which one is their main strength, because the skills are different.

Worth separating two different things people mean by this term. One is a marketing agency that uses AI internally to do its own work faster, writing copy, building ad creative, analyzing campaign data, the agency's process, not something it hands to you. The other is an agency, or a builder like me, who builds AI marketing systems that become your business's own asset: a lead follow-up workflow, a chatbot, a CRM connection you keep and run yourself. This guide covers hiring the second kind. If you specifically want to know how marketing agencies themselves are using AI to serve clients, see my guide to AI for marketing agencies instead.

What do AI marketing agencies do?

• Content and SEO: They research topics, draft blog posts and update old pages. A good agency has an expert edit every piece before it goes live.
• Ads: They write many versions of an ad, test them and move budget to the ones that work.
• Email and text campaigns: They write messages, split your list into groups and send each group the right offer.
• Chatbots: They set up an AI chat on your website that answers questions and books calls.
• Lead follow-up: They make sure every new lead gets a fast reply and a set of follow-ups.

What is AI marketing automation?

AI marketing automation means software that runs marketing steps on its own, with AI making some of the choices. Here are some common examples:

• New lead flow: A lead fills in your form. The AI reads the answers, scores the lead and sends a reply that fits their need. Leads who are ready to buy get a booking link right away. My guide to AI lead qualification covers this in depth.
• Website chat: An AI chatbot answers common questions at any hour and passes serious buyers to your team. See my guide to an AI chatbot for business.
• Review requests: After a job is done, the system asks happy customers for a review.

The best automation is connected to your CRM. Then every message, reply and sale is in one place, and you can see what brought in revenue.

What rules apply to AI marketing?

Using AI does not change the law. The FTC launched Operation AI Comply in September 2024. Its chair at the time said, "Using AI tools to trick, mislead, or defraud people is illegal." These rules matter most for AI marketing.

Fake reviews

The FTC's final rule on fake reviews, announced in August 2024, bans reviews that claim to come from someone who does not exist. The FTC names AI-generated fake reviews as an example. It also bans reviews from people who never used your product, and it lets the FTC seek civil penalties against knowing violators.

AI content and Google

Google does not ban AI-written content. Its guidance says the content must still meet its search rules and spam policies. Google warns that using AI to make many pages without adding value for users may break its policy on scaled content abuse. It also says to fact-check and review all AI-generated content, because AI predicts likely words and can get facts wrong.

Marketing email

The CAN-SPAM Act applies to every marketing email, whether a person or an AI wrote it. Each email needs an honest subject line, your postal address and a clear way to opt out. You must honor opt-outs within 10 business days. The FTC says you can't contract away your legal duty by hiring someone else to send your email. Penalties reach up to $53,088 for each email that breaks the law.

Texts and AI calls

Marketing texts sent with an automated system need the customer's prior express written consent under FCC rules. In February 2024, the FCC ruled that AI-generated voices count as "artificial" voices under the TCPA. That means AI voice calls need the person's prior express consent unless an exception applies. If the call sells something, the FCC requires prior express written consent. My guide to text message marketing covers the texting rules in full.

If an agency breaks these rules for you, your business can still be held responsible. Ask any agency how it handles each one.

How do you choose an AI marketing agency?

Look for proof you can check

Ask for live campaigns, real websites or reports you can see. Ask what changed for that client, such as more leads or more booked calls.

Ask who checks the AI's work

Every piece of AI content should have a named person who reads it before it goes live. For claims about health, money or the law, that person should know the subject.

Keep your accounts in your name

Your ad accounts, analytics, email platform and website should belong to your business. The agency should work inside them as a user. If you part ways, you keep your data and history.

Tie reports to sales

Clicks and views are easy to grow. Ask the agency to report on leads, booked calls and revenue, using data from your CRM.

Questions to ask any AI marketing agency

• Which tasks does AI do, and which do people do?
• Who reviews AI content, and what do they check?
• Which AI tools will you use, and does our customer data go into them?
• Who owns the accounts, content and automations you build?
• How do you follow the FTC review rule, CAN-SPAM and texting consent rules?
• What happens to our work if we end the contract?

What are the red flags?

• Guaranteed rankings: No one can promise a top spot on Google.
• Hundreds of AI pages a month: Mass content with no expert input risks Google's scaled content abuse policy.
• Review services: Any offer to write or buy reviews breaks the FTC rule.
• A secret "proprietary AI": If they can't show you what it does, treat the claim with care.
• They hold your accounts: You should never have to ask for access to your own ad account.
• Long lock-in contracts: A good agency is happy to start with a short first phase.

How do AI marketing agencies charge?

Most agencies use one of these models:

• Monthly retainer: A set fee for an agreed set of work each month.
• Project fee: A fixed price for one piece of work, such as setting up a lead follow-up flow.
• Performance fee: Part of the fee depends on results, such as leads or sales.

Prices vary a lot by scope and agency. Ask each agency for a written scope, a fixed price on the first phase and a clear list of what is not included. Ad spend and tool fees are often billed on top, so ask about those too.

When should you skip the agency?

You may not need an agency at all if your budget is small or your needs are simple. Many email, social and CRM tools now include AI writing and basic automation. If you or a staff member can spend a few hours a week on marketing, these tools may be enough.

An agency makes more sense when you have a real ad budget or need a lot of content. It also helps when nobody on your team has time to run campaigns.

When does a custom AI marketing system make sense?

I build this kind of system: AI workflows and software, such as lead follow-up systems, chatbots and CRM connections that fit how your business sells. I would start by mapping where your leads come from and what happens to each one today. Then I would build the flow, connect it to your CRM and test it with real leads. The lead flow and every account stay in your business's name, and I keep the system working after it goes live.
