What does sendEmail do?

Send an email. It is one of the tools The Cloud MCP server gives every connected AI.

How do I use sendEmail from Claude or ChatGPT?

Connect your AI to The Cloud at https://mcp.thecloud.so/mcp and sign in once. Then ask Claude, ChatGPT, Cursor or any AI connected to The Cloud "email X", and it calls sendEmail.

Is sendEmail safe to let an AI call?

sendEmail deletes or sends, and calling it again does not undo it, so a careful client confirms with you before it runs. It reaches a system outside The Cloud on your behalf.

Arguments

blocksobject[]optionalStructured rich email body. When present, it wins over richBody and body for the HTML part; bodyHtml wins over it.
bodystringoptionalPlain text email body. Required unless `bodyHtml`, `blocks` or `richBody` is provided; when combined with any of them, this is the explicit text/plain part (otherwise that part is derived from the HTML).
bodyHtmlstringoptionalYour own finished HTML email (a designed transactional email: receipt, confirmation, welcome) sent 1:1 as the HTML part. Precedence: bodyHtml wins over blocks and richBody for the HTML part; `body` is the explicit text part, else the text…
richBodystringoptionalMarkdown email body for formatted mail. Supports paragraphs, h1-h3 headings, bold, italic, links (a bold link is `[**text**](url)` or `**[text](url)**`), lists, blockquote, inline and fenced code, horizontal rules, image URLs, and inline…
acknowledgedstring[]optionalBuilt-in outbound checks you are knowingly relaxing for THIS send. Pass ["humble-ask"] only when the user wants the text sent as written after the humble-ask refusal; acknowledgedReason is required with it.
acknowledgedReasonstringoptionalWhy the acknowledged check is relaxed for this send, in one line. Logged with the rail and the phrases it let through.
accountIdstringoptionalAlias of `from`: the accountId from listMailAccounts. Takes precedence over `from` if both are given.
attachmentsobject[]optionalCloud files to attach, in order: up to 20 files, 25 MB in total. Page exports are not attachable, so attach the PDF as a Cloud file if there is one. Only promise an attachment after the result comes back with it in `attached`.
bccstringoptionalBCC email address (optional)
ccstringoptionalCC email address (optional)
docContractstringoptionalThe type-slug of the doc contract this is filed under (e.g. "handoff-memo"), when it is a staple rather than ordinary prose. The server validates the text against that contract and refuses a malformed one, handing back the contract's…
fromstringoptionalAccount to send AS. "shop-sender" requires the verified sender for the Space in scope. An accountId or email from listMailAccounts always sends as that Gmail account, even when a Space is in scope. Omit from to use the verified shop…
overridebooleanoptionalExplicit escape hatch for a legitimate 1:1 human send to a suppressed OR recently-touched recipient. Omit/false by default: a suppressed (unsubscribed/bounced/complained) address is refused, and so is a CRM contact already touched inside…
replyAllbooleanoptionalReply to EVERYONE on the original (its sender plus every To recipient in To, its Cc in Cc), minus the user's own addresses. Only meaningful with replyToMessageId and no explicit `to`.
replyTostringoptionalReply-To address for a new shop-sender email. Omit to use the shop sender's configured reply address.
replyToMessageIdstringoptionalMessage ID to reply to (optional)
spaceIdstringoptionalSpace id from listPageSpaces. With from omitted, its verified shop sender is used. Gmail is the fallback only when that sender is not verified. An explicit Gmail from ignores this and sends as that account.
subjectstringrequiredEmail subject line
tostringoptionalRecipient email address. Omit ONLY when replying (replyToMessageId set): the recipients are then composed from the original message.
viastringoptionalWhich account carries the send. "gmail" (default): the user's connected Gmail. "resend-connection": their own Resend account and verified sending domain (see connectResend); replies are not supported on that rail. The consent floor is…
