Can Claude send emails? Yes.

Short answer: Claude can send real emails — not just drafts — through your own SMTP server, from any mailbox (Gmail, Outlook, iCloud, OVH, Infomaniak, custom), using the Model Context Protocol (MCP).

The catch: Anthropic's first-party connector inside Claude.ai is limited to Gmail and Outlook, and focuses on draft creation. To actually send confidently from any provider, you need an MCP email server like MailMCP. Here is how it works.

2-minute setup

Create a free MailMCP account at mailmcp.io
Add your mailbox in the dashboard (IMAP host + SMTP host + credentials)
Copy the generated MCP URL into Claude Desktop's claude_desktop_config.json
Restart Claude Desktop — the tools appear automatically
Ask Claude: "Send an email to alice@example.com saying we are on for Thursday"

Why the native Claude email integration is not enough

Anthropic provides Gmail and Outlook connectors inside Claude.ai. They work well within their narrow scope: read recent mail, draft a reply, summarise a thread. Three real limits become obvious within a week:

Gmail and Outlook only. OVH, Infomaniak, iCloud, custom domains — not supported.
Draft-first behaviour. Real sending requires extra clicks; many actions stop at drafting.
Claude.ai only. If you also use ChatGPT, Cursor, Windsurf or n8n, you need a separate integration each time.

MCP solves all three. One MailMCP setup works across every MCP-compatible AI client and supports any IMAP/SMTP provider.

What Claude can actually do with your inbox

Once MailMCP is connected, Claude has 15 tools available. The most-used:

send_email

Real send via SMTP, with attachments, Cc, Bcc, Reply-To.

schedule_email

Send at a future date — Monday 8:45am, "in 3 days", etc.

draft_email

Save a draft in your Drafts folder for human review.

list_emails + read_email

Browse and read messages directly in conversation.

search_emails

Full IMAP search by sender, subject, date range, keywords.

move_email, mark_read, flag_email

Full folder + flag management — triage like a real client.

Example prompts that just work

"Reply to Carole confirming Thursday 2pm and add the event to my calendar."

"Find unpaid invoices in my inbox from the last 30 days and forward them to comptabilite@mycompany.com."

"Schedule a follow-up to alice@startup.example for Monday 8:45am: friendly tone, two paragraphs, reference last week's call."

"Triage my inbox: archive newsletters, draft replies to clients, flag anything urgent."

Frequently asked

Can Claude send emails without my approval?

Yes, if you instruct it to. Claude will send any email you ask it to send through MailMCP. You stay in control: you decide whether to ask Claude to draft (review before send) or to send directly. There is no autonomous sending without your prompt.

Does Claude send emails from my real email address?

Yes. Emails are sent through your own SMTP server using your real address. Recipients see the exact same From, Reply-To, and signature as if you sent the message yourself from your mail client.

Can Claude send to multiple recipients or with attachments?

Yes. Multiple recipients (To, Cc, Bcc) and file attachments are both supported. You can also schedule a send for a future date and reply to existing threads with proper In-Reply-To headers.

Does it work with Gmail only?

No. MailMCP works with any IMAP/SMTP mailbox: Gmail, Outlook, iCloud, OVH, Infomaniak, LWS, Yahoo, Free, Orange, or any custom mail server.

Is this an Anthropic feature?

Anthropic ships first-party Gmail and Outlook connectors inside Claude.ai, but they are limited to those two providers and focus on drafts. To send real emails from any provider, you need an MCP server like MailMCP that exposes the full send/reply/schedule capabilities of your SMTP.
