SendRaven vs AgentMail
AgentMail gives your agent a mailbox. SendRaven lets it run your product's mail.
AgentMail starts from a different primitive: the inbox. An agent gets a real address, persistent history, threads, labels and drafts, over an API and an MCP server. If what you are building is an agent that has its own email identity and corresponds on its own behalf, that is the right shape and we are not it.
SendRaven starts from your product. Mail goes out from your domain to your customers, campaigns and automations included, and the agent holds the conversation under limits a person set. Threads and stripped replies are in both. The cap, the allowlist, the approval hold, the reputation gate and the one-meter pricing are only here.
Inboxes for AI agents: each agent gets its own address, threads and webhooks. Checked 2 September 2026 against agentmail.to.
- An inbox per agent, with labels, drafts and websockets. If the agent is the correspondent rather than your product, this is the model.
- Per-tenant isolation through pods, which matters if you are building a platform where each customer gets its own agent.
- Longer message retention than SendRaven's thirty days of raw inbound.
Feature by feature
What each one does when you ask it to.
| Edge | SendRaven | AgentMail |
|---|---|---|
| Priced per email sent, never per contactPricing by list size charges most to the customer whose list is growing, which is the point of the product. | Yes. One meter. A contact is free. | No. per inbox and per plan: $20/mo for 10 inboxes and 10,000 emails |
| Transactional, campaigns and automations on one planTwo products means two suppression lists that disagree and a price gap that rewards mislabelling campaigns as transactional. | Yes. One key, one plan, one dashboard, one suppression list. | No. no campaigns or automations |
| The reply is a thread, not a webhookA webhook hands you a raw message and leaves you to work out which conversation it belongs to. | Yes. Joined on Message-ID to the message it answers. | Yes. |
| Quoted history stripped from repliesThe third reply in a thread is mostly the first two quoted back. A model reading it pays for that and gets confused by it. | Yes. text is what they typed; raw_text is the whole body. | Partly. thread objects; stripping not documented |
| One query for what is awaiting a replyThis is the poll an agent actually runs. Without it you build a state machine over inbound events. | Yes. GET /v1/threads?awaiting_reply=true | Partly. labels and drafts; no awaiting-reply query documented |
| Per-key daily cap and recipient allowlistA workspace quota trips after an agent has mailed thousands of people. A key limit trips before. | Yes. daily_send_limit and allowed_recipients on the key, checked on every send. | No. |
| Human approval hold on a keyThe only way to let an agent write mail without letting it send mail. | Yes. requires_approval drafts the message and waits for a person. | No. |
| Campaign refused before it starts on bounce or complaint rateReputation dashboards report the damage. A gate prevents it. | Yes. Checked in the send path; the preview call says whether it will be allowed. | No. |
| Unsubscribe cancels queued sends and ends the sequenceDoing only the first is how a working unsubscribe still delivers day three of a welcome series. | Yes. Two writes: suppress the address, cancel what is scheduled for it. | No. no sequences |
| Opt down by topic, per personGiven only all-or-nothing, people press spam instead, and a complaint costs the domain far more than an opt-out. | Yes. Preferences on (email, topic), not on a contact row. | No. |
| Remote MCP server with no stored credentialsA server that holds its own database credentials is a shared identity for every caller. | Yes. mcp.sendraven.ai, OAuth or a Bearer key, reaches exactly what the key can. | Yes. |
| llms.txt and an unauthenticated OpenAPI documentA model decides what it is holding from the description document. Generated ones say what, not which. | Yes. Both public, written by hand, so an agent can read them before it has a key. | Partly. |
| Errors written for an agentA client that backs off on 429 retries a payment problem forever. A model that sees an error retries a held draft. | Yes. 402 for out of plan, not 429. pending_approval is a status, not an error. | No. |
| Inbound included and freeCharging for the reply discourages the half of email that makes it a conversation. | Yes. Replies cost nothing and land in the thread. | Yes. the core product |
| Free tier without a cardA trial that expires is a deadline, not a tier. | Yes. 3,000 emails a month, inbound included. | Yes. 3 inboxes, 3,000 a month |
| Overage per 1,000 at the entry paid tierThe overage rate is the real price for anyone who grows. | Yes. $0.30 on Pro, $0.20 on Scale. | Not applicable. plan-capped |
| Usage pricing without tier cliffsTiers do not hurt at the boundaries. They hurt in the middle, which is where most senders live. | Yes. Included allowance, then a flat rate per thousand. | No. |
Questions
Asked by people choosing between the two.
Is SendRaven an AgentMail alternative?
For an agent that needs its own mailbox, no; AgentMail is built for that. For a product that sends transactional mail and campaigns from its own domain and wants an agent to handle the replies safely, yes. The two overlap on threads and MCP and differ on everything around sending.
Try it on one domain first.
