# Connect an SMTP/IMAP sender email

`POST /sender-emails`

## Request

- Base URL: `https://api.emailchaser.com/r`
- URL: `https://api.emailchaser.com/r/sender-emails`
- Auth: HTTP bearer

Connects an SMTP/IMAP mailbox to the workspace using an app password, with no browser step. Google and Microsoft mailboxes are not supported here because both require an interactive consent screen; connect those in the app. The address must be a business domain.

## Request body

- ModelsConnectSenderEmailRequest
  - `email` string, required
  - `firstName` string
  - `imapServerUrl` string, required: ImapServerUrl and SmtpServerUrl accept the provider's host, optionally with a port, for example "imap.fastmail.com:993".
  - `lastName` string
  - `loginString` string: LoginString defaults to the email address when omitted, which is what most providers expect.
  - `password` string, required
  - `smtpServerUrl` string, required
