MailSlurp provides programmable email and SMS inboxes, sending, testing, webhooks, and deliverability tools through a REST API.

## Tools

- **Create Inbox** — Create a MailSlurp HTTP or SMTP inbox. HTTP inboxes are the default and can send and receive; SMTP inboxes are receive-only.
- **Delete Inbox** — Permanently delete one MailSlurp inbox by UUID, including its email address and all emails it contains. This destructive action cannot be undone.
- **Get Account Info** — Return the connected MailSlurp account identity, state, account type, subscription type, and creation time. Use this to check account availability before attempting quota- or plan-sensitive operations.
- **Get Email** — Get one fully hydrated received email by UUID, including parsed headers, body content, recipients, and attachment IDs. Fetching hydrated content may mark the email as read.
- **Get Inbox** — Get one MailSlurp inbox by UUID, including its email address, type, labels, and lifecycle state.
- **List Contact Groups** — List saved MailSlurp contact groups with optional creation-time filters. Returns one page and a continuation cursor.
- **List Contacts** — List saved MailSlurp contacts with optional search and creation-time filters. Returns one page and a continuation cursor.
- **List Domains** — List custom domains configured for the connected MailSlurp account, including identifiers, domain type, and DNS verification state.
- **List Emails** — List received emails across the account or one selected inbox with unread, exact-search, favorite, plus-address, and time filters. Returns one page and a continuation cursor.

- **List Inboxes** — List MailSlurp inboxes with optional search, tag, type, domain, favorite, and creation-time filters. Returns one page and a continuation cursor.
- **List Sent Emails** — List sent-email records, optionally filtered by source inbox, exact identifier/address search, and creation time. Returns one page and a continuation cursor.
- **Send Email** — Send an email from a specific MailSlurp inbox to addresses, saved contacts, or one contact group. Supports plain text or HTML, uploaded attachment IDs, and saved templates. The legacy endpoint confirms acceptance but does not return a sent-
