Email Bump vs AgentMail
AgentMail sells an inbox API for AI agents and does it well. Email Bump is a full email platform whose receiving side does the same job, priced on a different axis and attached to contacts, campaigns and flows.
The short version: they are better if you need IMAP. We are better if you need a lot of addresses, or anything that happens after the mailbox.
Which one you want, in three sentences
Choose AgentMail if a human needs the mailbox in a mail client IMAP lets a person open the same inbox an agent is working, in Apple Mail or Outlook. We have no IMAP: mail is read over the API, a WebSocket, the CLI or the dashboard.
Choose Email Bump if you need more than a handful of addresses There is no inbox object, so every address on your receiving domain already works. An address per ticket, per customer or per agent run costs nothing and needs no provisioning call. On a per-inbox plan, 150 of them is $200 a month.
Choose Email Bump if the agent's job grows Contacts, consent, campaigns, automated flows and delivery analytics are the same product, not a second vendor. The reply an agent sends is logged next to every other email that person has had.

Where AgentMail wins
Real-time push A WebSocket delivers a message to a connected agent the moment it arrives. Our webhook is a POST to your endpoint — usually a second later, but it is a different shape, and if you are holding an interactive session open theirs is the right one.
IMAP You can open an AgentMail inbox in any mail client. That makes a human and an agent sharing a mailbox trivial. Here a human uses the dashboard and the agent uses the API, which is fine for most teams and wrong for some.
Purpose-built for exactly this Their whole product is the agent mailbox — drafts with scheduled sending, labels, multi-tenant Pods for platform builders. Ours is an email platform whose receiving side happens to serve agents very well. If you want nothing but the mailbox, theirs has fewer concepts in the way.
Email Bump vs AgentMail, asked and answered
Is Email Bump a drop-in replacement for AgentMail?
For the common path — get an address, receive, read, reply, forward, and be pushed a notification over a socket — yes, and there is no inbox to provision. Not if you depend on IMAP, which we do not have.
How do I give each agent its own address?
Pick one. `[email protected]` receives without being created, as does every other local part. There is no registry to keep in sync and nothing to clean up when an agent is retired.
What does it cost to run 150 agent inboxes?
Nothing extra — addresses are not a billable unit here. Plans are priced by contacts, so what you pay depends on how many people you store, not how many addresses your agents answer on.
Can an agent do all of this without a human opening a browser?
Yes. Sign-up, email confirmation with a code, domain setup, sending and receiving are all API calls, and there is an MCP server and a set of skills that teach an agent the sequence.
