Answer Everfit Inbox messages with an AI agent

1. Open Inbox in the web app, or tap the Inbox icon in the coach app, and use the Unread tab to bring conversations that still need an answer to the top.
2. Open a conversation. To answer one specific message on the web, hover over it and click Reply; on mobile, swipe left or press and hold the message.
3. The panel on the right of the conversation shows the client's local time, notes and activity updates. Limitations, injuries and this week's training calendar need the client overview, opened by clicking the client's name.
4. If AI Smart Response is on, a Draft badge marks conversations with a reply ready. Review the draft in the chat box, edit it and send.
5. Repeat per client. Reply with AI is offered on a client's text message, and a reply sent with a mistake can only be edited within 60 minutes.

Every evening, go through my unread Everfit Inbox, check each client's workouts this week and their notes, draft a reply to the simple questions, and flag anything about pain, injuries or billing for me.

1. 01

   Start from Unread, oldest first

   list_conversations with unread_only gives the queue, and teammate chats never show up in it. The agent works from the longest wait down, so the client who wrote yesterday morning is not buried under tonight's messages.

2. 02

   Read the thread and the client together

   get_conversation shows the recent messages, including what you already said, so a question you answered an hour ago in another message gets no second answer. get_client adds limitations and notes, and list_workouts adds this week, so "can I swap rows?" is answered against Thursday's actual session.

3. 03

   Draft only what is safe to draft

   Logistics and exercise swaps that fit your notes get a draft. Pain, injury, medication, refunds and billing get none: the agent flags them with one line on what the client asked. A message that is only a voice note or a video is flagged for you to open in Everfit.

4. 04

   Keep your voice, promise nothing new

   Drafts follow the length and tone of your past replies in that thread and use the client's first name. When the right answer needs a calendar change, the draft says you will update it, and the agent lists the change for you instead of making it.

5. 05

   Send after approval, one reply at a time

   send_message waits for your OK per reply by default, and approved replies go out under your name. When you rewrite a draft, the agent reuses your wording for the next similar question in the same run.

• Everfit Inbox stores every chat that has no client in it, the ones with teammates, in a separate Team tab.
• Everfit lets a coach edit only their own plain text messages, sent within the last 60 minutes and edited fewer than 5 times; images, videos, GIFs and voice messages cannot be edited.
• One Everfit Inbox message can carry up to 5 images or videos, on web and mobile.
• Everfit AI Smart Response spends AI credits on each draft; when a coach reaches the monthly limit, drafting pauses, manual messaging keeps working, and unused credits expire at month end.

send_message asks for your OK by default. To run it daily without you, switch confirmation off for that tool in your dashboard.
