Is AgenticEmail a drop-in Mailinator replacement?

For programmatic use, yes and more: POST /v1/inboxes gives you a private address instantly, GET returns parsed messages, and webhooks push new mail in real time. For quick manual browser checks, try our free fake email generator tool - no signup needed.

Are AgenticEmail inboxes public like Mailinator's?

No. Inboxes are private to your organization and readable only with your API key or dashboard session. There is no public webmail view of your mail.

Can I keep an inbox permanently?

Yes. Inboxes persist until you delete them, so an address can serve a long-running agent or workflow rather than expiring like a temp inbox.

Alternatives

Mailinator alternative: private inboxes your code can send from

Mailinator popularised the public disposable inbox: any address @mailinator.com exists implicitly, and anyone can read it. That is brilliant for quick manual checks - and exactly wrong for anything private, persistent, or two-way.

AgenticEmail approaches the same problem from the infrastructure side: inboxes are private resources you create with one API call, they can send and reply (not just receive), and every inbound message arrives as parsed JSON via webhook or WebSocket. If you have outgrown pasting addresses into a public inbox site, this is the next step.

Mailinator vs AgenticEmail at a glance

Feature	Mailinator	AgenticEmail
Inbox privacy	Public inboxes on the free tier - anyone who knows the address can read the mail. Private domains are a paid feature.	Private by default. Every inbox belongs to your org and is only readable with your API key.
Sending & replying	Receive-oriented; built around inspecting incoming messages.	Full two-way: send, reply (with automatic threading), and forward from any inbox.
Programmatic access	API available on paid plans.	API-first from the free tier: REST, TypeScript & Python SDKs, webhooks, WebSocket stream.
AI agent support	Not a focus.	Hosted MCP server, per-inbox agent prompts, auto-parsed attachments (PDF to markdown) in webhook payloads.
Custom domains	Supported on paid plans.	Bring your own domain; SPF, DKIM, DMARC and receiving records generated, pushed to your DNS, and verified for you.

Competitor details reflect public information and can change - always confirm on their site.
