What an iTeam agent does with the ActiveCampaign API
E-mail click becomes a conversation
When a lead clicks the offer, the webhook triggers the agent, which pulls the context and opens a WhatsApp conversation with the person.
Clean tags
The agent reviews duplicate or unused tags and proposes a consolidation for marketing to approve.
Qualified event lead
Webinar registrants get questions from the agent. Those who fit the profile become deals in the pipeline with a priority tag.
Unsubscribe respected everywhere
Anyone who asks to stop on WhatsApp is marked in ActiveCampaign by the agent, so they receive no more campaigns.
