In their own words, as submitted to SaaSHub.

Leads arrive at info@, at sales@, and in each salesperson's own inbox, mixed in with client questions, invoices and noise. On a busy day some are never answered, and you are the one answerable when a real lead goes quiet. InboxAgent watches the mailboxes you already have, on Microsoft 365, Gmail,...

As answered by people managing InboxAgent and Black-Screen.dev.
InboxAgent's answer
It is read-only. InboxAgent reads the mailboxes you already have and never sends mail from them, never moves a message, and never files or deletes anything. Most tools in this category work by forwarding your mail into their own system, after which your own mailbox stops being the record of what arrived. Nothing here changes your mailbox.
For Microsoft 365, Gmail and Zoho Mail that is enforced by those providers rather than promised by us. The permissions we request are read-only, so you can check it on the consent screen before you click Allow.
InboxAgent's answer
InboxAgent's answer
Businesses whose sales inquiries arrive by email, at shared addresses like info@ and sales@ as well as in individual inboxes. Typically service businesses that sell by email: agencies, professional services, trades and field service, suppliers and distributors.
It fits particularly well where email is the main source of leads and there is no proper place to manage them. Every lead lands on a board with an owner and the original email attached, moves through stages you name yourself, carries up to ten fields of your own, and can be exported to CSV at any time.
InboxAgent's answer
Sales inquiries arrive in the same mailbox as invoices, supplier mail and noise. Everyone can see them and nobody owns them, so on a busy day some are never answered, and the business often finds out only when a customer goes elsewhere.
InboxAgent exists to answer one question about that mailbox: who owns this email, and has anyone actually dealt with it.
InboxAgent's answer
.NET on Microsoft Azure App Service. Microsoft Graph, the Gmail API, the Zoho Mail API and IMAP for mailbox access, all with read-only permissions. OpenAI for classification.
