What changes at the agency with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. These are four everyday situations at the agency before and after the CertuAI agent.

What does a conversation handled by the AI look like?
Example conversation
Agency AI agent
Customer: How much does it cost to manage my paid traffic?
AI agent: The investment range for traffic management is your price. What is your industry and media budget?
Customer: I want to schedule a call with you
AI agent: I have your open time slots on the sales calendar.
Is an AI agent or manual customer service worth more for marketing agencies?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. With manual service, someone at the agency has to stop what they are doing; with the CertuAI agent the answer goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Lead asking for a quote while the team is in a meeting | Waits hours for a response, at an agency that sells fast response | Answered right away, with industry, budget, and goal gathered in the conversation |
| Qualification before the call | The manager finds out in the meeting that the lead has no media budget | Revenue, budget, and goal arrive ready, and the call only happens if it is worth it |
| Proposal sent with no reply | Sits forgotten in the outbox until the client closes with someone else | A polite, persistent follow-up reopens the conversation days later, on its own |
| Booking the diagnostic meeting | Five rounds of messages just to find a time | Calendar checked and meeting closed within the same conversation |
| Active client asking for a report on WhatsApp | The request gets lost among lead messages and turns into a complaint at renewal | Recorded in the CRM and routed to the person in charge of the account right away |
