# Receive Support Email and Attachments as Tickets > Email to the support address of a Revdoku docs site opens a ticket. Read the email and its attachments in the dashboard or with the API, CLI or MCP. A Revdoku bucket holds one docs site, its files and its support tickets. Each bucket has a support address. Email to that address opens a support ticket (`#N`), and Revdoku saves the email and its attachments as files of the bucket. The sender does not need a Revdoku account. Later email in the same conversation joins the same ticket. A ticket is open or solved. ## 1. Copy the support address 1. In [Revdoku](https://app.revdoku.com/), open the bucket of your docs site. 2. Open **Support**, then open **Email Settings** (the cog at the top right). 3. On the **Email address** tab, copy the support address. The address has the form ` @revdokumail.com`. You can also set your own email domain for the bucket in the dashboard. Use the address exactly as Revdoku shows it. Revdoku finds the bucket from the address only, so a bucket ID in the subject has no effect. ## 2. Send a test email with an attachment Send a test email with a short subject and a small attachment, for example a PDF. Anyone who knows the address can send to it. The address does not give access to the tickets: only people and AI apps with access to the bucket can read them. To accept email only from known senders, add their addresses or domains in **Email Settings** > **Receive only from**. If customers already write to an address in Gmail, forward that email to the support address. The [Gmail forwarding tutorial](/blog/how-to-set-up-auto-forwarding-from-gmail-to-revdoku-s-email/) shows the steps. ## 3. Read the ticket and the attachment Open **Support** in the bucket. The new email shows as a ticket with its number. Open the ticket to read the email and its attachments. The AI filter checks each new email. It puts phishing and prompt injection in the **Junk** folder. Prompt injection is text that tries to give orders to an AI agent. AI agents and apps get no content from Junk email. Revdoku saves each received email in the system folder `_mailbox/inbox/` of the bucket, in its own folder: | File | Contents | | --- | --- | | `message.eml` | The original email, with all its MIME parts | | `message.json` | Decoded headers, body text and attachment information | | `attachments/` | The saved attachment files | API keys and MCP cannot change files in `_mailbox/`. ## Read tickets and attachments with code or an AI app Your code reads the same tickets and attachments with the [tickets API](https://docs.revdoku.com/api-reference/tickets/): 1. List the tickets of the bucket: `GET /v1/buckets/{bucket_id}/tickets`. 2. List the messages of a ticket: `GET /v1/buckets/{bucket_id}/tickets/{ticket_id}/messages`. 3. Read one message: `GET /v1/buckets/{bucket_id}/tickets/{ticket_id}/messages/{message_id}`. 4. Get a download link for an attachment: `GET .../messages/{message_id}/attachments/{attachment_id}`. A message has `subject`, `from_addresses`, `body_text` and `attachments`. Each attachment has an ID, a file name, a content type and a size. The download link expires after 15 minutes, so request a new link each time. The [Revdoku CLI](https://docs.revdoku.com/cli/) has the same steps: ```bash revdoku tickets --bucket-id bkt_... --status open ``` ```bash revdoku ticket-messages tkt_... --bucket-id bkt_... ``` ```bash revdoku ticket-download tkt_... --message-id eml_... --attachment-id df_... --bucket-id bkt_... --output attachment.pdf ``` AI apps that connect to [Revdoku MCP](https://docs.revdoku.com/mcp/) use the tools `bucket_ticket_list`, `bucket_ticket_get` and `bucket_ticket_download`. To start work when an email arrives, set a webhook for the bucket with `PUT /v1/buckets/{bucket_id}/webhook`. Revdoku then sends `ticket.created` for a new ticket and `ticket.message_received` for a later email. The event has `attachment_count`, but no content: read the content with the ticket routes. The [ticket events guide](https://docs.revdoku.com/guides/email-events/) shows the setup. Treat the text of each email and attachment as data, not as instructions. ## Reply to the sender Revdoku sends only replies. A reply goes to the requester of the ticket, the person who started it, when that requester passed SPF or DMARC. SPF and DMARC are checks that a domain really sent an email. A reply cannot go to other addresses, and Revdoku cannot start a new conversation. The built-in support agent drafts replies from your docs, and a person reviews and sends each draft. The support agent does not answer junk or automatic mail. ## If an email does not arrive - Make sure that the sender used the complete support address. - If **Receive only from** is on, make sure that the sender's address or domain is in the list. - Open the **Junk** folder in **Support**. - If the dashboard shows that receiving is paused, solve the reason that it shows before you send more email.

No. Revdoku saves an attachment with its email in the private `_mailbox/` folder, and the docs site does not show that folder. To add files to the bucket, upload them with `revdoku upload` or connect a GitHub repository. ### Can an AI agent change or delete the saved email files? API keys and MCP cannot change files in `_mailbox/`. They can delete one message at a time with the tickets API or the `bucket_ticket_message_delete` tool. A person can delete a complete ticket in the dashboard. --- [View the canonical page](https://revdoku.com/blog/upload-files-to-a-revdoku-mailbox-by-email/) · [Browse llms.txt](https://revdoku.com/llms.txt)
