# Revdoku vs Mailtrap for AI Agent Email

Mailtrap is an email delivery and testing platform with email infrastructure for AI agents, sometimes called the Mailtrap agent mailbox: hosted inboxes, parsed incoming email and replies through an API. Revdoku gives each agent its own mailbox, keeps email and attachments as files and connects to AI apps through a hosted MCP server.

## Short answer

**Choose Mailtrap** if your agent must send email as well as receive it, you already use Mailtrap for sending or testing, or you need a SOC 2 report today.

**Choose Revdoku** if your agent mostly receives email and documents, works from ChatGPT, Claude or a coding agent, and should get mail that is checked for malware and prompt injection first.

## Mailtrap inbound email vs a Revdoku mailbox

| | Revdoku | Mailtrap |
| --- | --- | --- |
| Address | One per mailbox, on Revdoku's domain or your own | Hosted inboxes on `inbound-mailtrap.io`, or your own domain ([receiving docs](https://docs.mailtrap.io/inbound-email/receiving-emails.md)) |
| How mail reaches your code | Signed webhook, WebSocket or polling | Signed webhooks, retried every 5 minutes, or polling the Messages API ([webhooks](https://docs.mailtrap.io/inbound-email/webhooks.md)) |
| Attachments | Saved as files in the mailbox | Download links |
| Replies | Replies to people who emailed the mailbox | Reply, reply-all and forward; hosted inboxes have a reply limit until you add your own domain ([agents page](https://mailtrap.io/email-infrastructure-for-ai-agents/)) |
| AI apps (MCP) | Hosted MCP server with sign-in in the browser | Local MCP server that runs with npx |
| Spam and malware | Malware scan and known spammers blocked; AI labels mark malicious prompts as `Junk` | Spam verdicts for inbound email under development |
| Activity log | For each person and agent | Enterprise plan |
| Compliance and data | EU region | SOC 2 Type II; data regions coming soon |
| Before you pay | Free to try, no card needed | Free plan with a monthly email pool ([pricing](https://mailtrap.io/pricing)) |

## When Mailtrap fits better

- Your agent sends new emails, not only replies.
- You already use Mailtrap for sending or for testing email.
- You need SDKs in many languages, such as Java, .NET or Elixir.

- Your agent receives documents and needs them stored as files for later tasks.
- Several agents share a mailbox, each with its own access.
- AI apps connect through a hosted MCP server without local setup.
