InboxNest

InboxNest gives founders who run several products a branded support address for each one (support@, billing@, hello@ and so on) and one shared inbox to answer them all. This connector lets Claude work in that inbox.

Claude can list the products on your account, list and search conversations across every product, and read a full conversation with each customer message. Reading never marks anything as read in InboxNest.

Replies are drafts first. When you ask Claude to answer a customer, it saves a draft on the conversation. You see it in InboxNest above the reply box, labeled as an AI draft, and you choose to send it, edit it, or discard it. Each conversation holds one draft, and a new one replaces the old.

Sending is off by default. Only the account owner can turn on "Allow AI apps to send replies" in Settings, and you must also tick the send permission when you connect. Even then, Claude cannot choose the recipient or the From address: replies always go to the customer on the conversation, from that product's branded address, and InboxNest's sending limits, suppressions and safety pauses still apply. With that switch on you can also allow Claude to flag conversations for follow-up, mark spam, or move them to Trash.

You connect by pasting the URL and signing in to InboxNest. There is no API key. You pick the permissions on the consent screen, can disconnect at any time in Settings → Connected AI apps, and can see every action Claude took in the activity log there. Customer-written text is labeled as customer content so it is treated as data, not instructions.
