The practical reason to use it.
Brevo works best when the production workflow is explicit, not just the integration label. Brevo gives InsertChat assistants access to 21 actions that can read data, update systems, and move work forward without leaving the conversation. Instead of asking users to switch tabs, your assistant can use Brevo to look up records, trigger actions, and keep the next step attached to the same conversation. You decide exactly which assistants get Brevo access, so support, sales, operations, and product workflows stay scoped to the right conversations. InsertChat keeps Brevo access scoped through authenticated accounts, so assistants act with the right user or workspace context. Use the same Brevo-enabled assistant across website embeds, the admin app, and API workflows so your team does not rebuild logic for every channel.
Teams usually adopt Brevo when they need record lookups, workflow actions, authenticated tasks, operational handoffs to happen inside the same assistant experience instead of bouncing into another portal. That is where the combination of user accounts, per-assistant access, knowledge base, embeds matters, because the chat surface has to stay grounded, helpful, and ready to hand off when the next step needs a human owner.
Brevo keeps scoped access, action execution, and handoff attached to the same conversation from start to finish, which is more useful in production than a connection that only exposes an app name.
