AgentMail comparison

Different jobs: an agent's inbox, or a harness for your product's mail.

AgentMail gives an AI agent its own email identity. The agent signs up for things, receives confirmations and holds real conversations as itself. Reclario is a private catch-all domain where you catch, read and assert on the mail and calendar invites your product sends. Most teams that compare the two need one of them, not both. This page is for working out which.

The difference

Where the two products diverge.

Participant vs harness

AgentMail's inbox belongs to the agent, which acts as a person would. Reclario's addresses belong to your test. Nobody is pretending to be a user; you're watching what your product sent and checking that it's right.

Catch-all, nothing provisioned

Any address on a Reclario domain takes mail without being created first, through the API or otherwise, and there's no per-address limit. AgentMail bills per inbox, so each persona is created and counted.

Calendar auto-RSVP

Send a real ICS invite to a tagged address and Reclario emails an iTIP reply to the organizer: accept, decline or propose a new time, after a delay if you tag one. AgentMail's documented product is email, and we found no calendar, ICS, or RSVP support.

Flat per domain

Reclario is $49/mo per domain with unlimited addresses. AgentMail prices by inbox count: free at 3, $20/mo at 10 plus $2 for each extra inbox, and $200/mo at 150, as of August 2026. Which one costs less depends on how many personas you need.

Private by default

Only members you invite can read mail on a Reclario domain, and nothing on it is listed or searchable. That matters because test mail routinely carries candidate names and offer details.

Built for assertions

With API keys and webhooks, CI can provision addresses, read messages and get a callback on delivery. Sandboxed rendering plus .eml and attachment downloads let you inspect exactly what shipped.

The pricing crossover is about 25 addresses.

Below roughly 25 addresses AgentMail is cheaper, and at three it's free. If you need a handful of agent inboxes, AgentMail is the better deal. Above that it flips. Reclario is $49/mo per domain with no address limit, so a hundred personas cost the same as three. At AgentMail's 150-inbox tier ($200/mo, August 2026), Reclario is still $49.

When AgentMail is the right call.

Use AgentMail when your agent needs to be somebody: own an address long-term, sign up for third-party services, receive replies and act on them, and carry a threaded conversation as itself. That's what AgentMail is built for, and Reclario is not a substitute. Reclario is the right tool when the mail is evidence. Your product sent it, and you need to catch it, read it and assert on it without borrowing a colleague's Gmail or writing to a real person.

FAQ

Common questions.

Is Reclario an AgentMail alternative?
Only for one job. AgentMail gives an AI agent its own inbox so the agent can take part as a real participant: it signs up for services, receives confirmations and holds threaded conversations. Reclario sits on the other side of the glass. It's a private catch-all domain for testing the mail and calendar invites your product sends. If your agent needs an email identity, use AgentMail. If you need to catch, read and assert on your product's outbound mail, use Reclario.
Do I have to create an inbox per address?
Not on Reclario. Your domain is a catch-all, so an address exists as soon as mail arrives for it. Make one up for each persona, ticket or test run without an API call or any provisioning. AgentMail bills by the inbox (3 on the free tier, 10 on Developer, 150 on Startup, as of August 2026), so each persona is something you create and count.
Which is cheaper?
It depends on how many addresses you need. AgentMail is free at 3 inboxes and $20/mo at 10, which is cheaper than Reclario. Reclario is $49/mo per domain with unlimited addresses, so it comes out ahead from roughly 25 addresses up and stays ahead from there. At AgentMail's 150-inbox Startup tier ($200/mo), Reclario is still $49. See Reclario pricing.
Does AgentMail answer calendar invites?
Its documented product is email: inboxes, threads, attachments, drafts, scheduled send, SDKs and an MCP server. We found no calendar, ICS, or RSVP functionality. Reclario replies to a real ICS invite for you. Send one to interview+accept@yourteam.reclar.io and an iTIP reply goes back to the organizer, so your scheduling flow can run to the end. More in calendar invite testing.
Can I use Reclario to staff an agent's product walk?
Yes. It suits that job because nothing has to be provisioned. An agent walking a product as several people (an admin, a colleague, a committee, a hiring manager) needs every one of those addresses to work before it starts, and on a catch-all domain they already do. See agent product testing.
Can I try Reclario free?
Yes. The public sandbox at public.reclar.io is free; you need a work email but no credit card. It is receive-only, so you can watch mail land but it won't send RSVPs. Auto-RSVP needs a private domain, and private domains come with a 14-day free trial.

Give your whole cast an address.

A private catch-all domain is $49/mo per domain and starts with a 14-day free trial. To watch mail land first, use the free public sandbox at public.reclar.io. It is receive-only and needs a work email, not a credit card.
