Mailgent vs Amazon SES
SES is a high-volume sending API. Mailgent is an identity and inbox for agents. Here's where the line falls, and why you usually want both at different layers.
Amazon SES is a workhorse for sending and receiving email at volume. It's cheap, scalable, and battle-tested — but it's infrastructure, not an agent's mailbox. You get an SMTP endpoint and an API; everything above that you build.
Mailgent operates a layer up. It gives an agent a real address, threaded inbox tooling, and the surrounding identity — vault, 2FA, calendar, signing key, wallet — so the agent can actually operate, not just emit messages.
What SES gives you
SES handles raw send and receive with strong deliverability once you've configured domains, DKIM, and reputation. It scales to millions of messages and bills per thousand.
What it doesn't give you: thread management, labels, rules, a per-agent identity, credential storage, 2FA, or anything agent-shaped. You assemble those yourself on top of S3, Lambda, and your own database.
What Mailgent adds
Mailgent gives each agent a distinct address and a typed API for threads, replies, labels, and rules — over REST or MCP. Around the inbox sit the capabilities an operating agent needs: a vault for secrets, TOTP for 2FA gates, a calendar, a did:web identity for signing, and a USDC wallet for payments.
It's the difference between a pipe and a mailbox with a person behind it. SES moves bytes; Mailgent gives the agent a presence.
When to use which
Use SES when you're blasting transactional or marketing mail from your application at scale and want the lowest per-message cost. Use Mailgent when an autonomous agent needs to receive, reason about, and act on email as itself — with identity and controls attached.
They aren't mutually exclusive: your app can keep sending bulk mail through SES while your agents live on Mailgent.
FAQ
Does Mailgent replace SES?
Not for bulk application sending. Mailgent is for giving agents an inbox and identity, not for high-volume transactional blasts.
Can I use both?
Yes. Many teams send app mail via SES and run their agents on Mailgent for the inbox and identity layer.
Does Mailgent handle deliverability?
Yes. Agents send from verified senders with DKIM and SPF configured, so you don't manage reputation infrastructure yourself.
Give your agent an inbox.
A real email address, a vault, 2FA, and an identity in one API call.
