TrashMail alternative: GrabMail vs TrashMail (Aionda Mail)

At a glance

Fourteen rows. Every TrashMail cell is what mail.aionda.com’s home page, imprint, privacy page and API reference said on 2 September 2026; every GrabMail cell is read from the constants the service enforces. “Partly” means a paid tier or a caveat the row cannot hold — the sections below say which.

Checked 2 September 2026. trashmail.com redirects permanently to mail.aionda.com, and the product now presents itself as encrypted groupware with disposable addresses inside it. Its API reference is a PDF from the TrashMail.net era, with session-cookie authentication. Where a figure is not published, the cell says so.

What TrashMail does well

TrashMail has been the German answer to “Wegwerf-E-Mail” for over twenty years, and the forwarding model has real advantages. Four things it does that GrabMail does not:

• The mail comes to you. A disposable address forwards to your real inbox, so a receipt, a newsletter or a password reset lands where you already read mail. GrabMail holds mail on its side, in public, for 5 days.
• Each address has a fuse. A lifetime in days and a number of forwards, set per address, so the one you gave a shop dies after three messages and the one you gave a friend never does. GrabMail has one rule for everything.
• Real privacy, on paper and in law. Zero-knowledge encrypted mailbox, servers in Germany, an imprint with a company behind it, and a Plus plan that lets you send under your own domain. GrabMail’s mailboxes are readable by anyone who knows the address.
• Two euros buys everything. Plus at 1.99 € a month: 10,000 addresses, unlimited forwarding, custom domains, a gigabyte of encrypted drive. GrabMail’s paid plan is for developers who need off-blocklist domains and starts at $24.

Where GrabMail is different

GrabMail is for the sign-ups whose mail you never want to see again, and for the programs that read mail for you.

• Nothing to create, nothing to manage. TrashMail is an address manager: log in, create, set the fuse, delete later. GrabMail has no account and no manager; trial@grabmail.io is an inbox because mail arrived at it, and it is nobody’s job to clean up.
• The mail stays away from your real inbox. A forwarder brings the mail to you; that is its purpose and its cost. For a one-time code or a download link, an inbox that keeps the mail on its side for 5 days and then deletes it is the cleaner tool. Burner, alias or temp mail is the longer version of this paragraph.
• A keyless API and an MCP server. TrashMail’s API logs in and carries a session cookie; it manages addresses rather than reading mail, because the mail is in your inbox. GrabMail’s three endpoints read a mailbox with a GET, and its MCP server lets an agent open one and wait up to 25 seconds for a message with nothing to sign up for.
• Your own domain, free. TrashMail’s custom domains are a Plus feature. Here one MX record at smtp.grabmail.io turns any domain into a catch-all inbox — public, unlimited, no plan.

Price, side by side

Aionda Mail’s prices are in euros per month; refund terms are not published. GrabMail’s only paid plan buys access to a pool of domains kept off the disposable-mail blocklists; everything in the table above stays free.

For developers: reading a mailbox

TrashMail’s API manages addresses, not messages — the messages are in your own inbox — so this section compares two different jobs. The command below reads a GrabMail mailbox with no header, no key and no account:

$ curl -sG https://grabmail.io/api/v1/mailbox --data-urlencode "address=anything@grabmail.io" | jq '{count, alias}'

TrashMail’s API, documented in a PDF from its TrashMail.net days, logs in with cmd=login, keeps a session cookie, and creates an address with a chosen name, domain, forward count and expiry. It is an automation of the address manager, and it works. What it cannot do is hand a test suite a message, because the message went to your inbox. GrabMail’s reference is three endpoints that do exactly that.

For a test that has to read a verification code, the difference is decisive: Python or Node.js polling a GrabMail mailbox with a deadline, against a TrashMail address forwarding to a real mailbox the test would then have to read by IMAP.

For AI agents

Aionda Mail has an assistant inside the product that creates and edits addresses, and lists “AI agents” as an Enterprise feature; it publishes no MCP server and no llms.txt. GrabMail’s server at https://grabmail.io/mcp gives an outside agent an inbox with no key: create_inbox, a blocking wait_for_message of up to 25 seconds, read_message.

Email for AI agents covers the four-call loop and the guard rails; the client guide has the configuration for Claude, Cursor and five others.

Switching from TrashMail

Most people should not switch — they should use both. Where a switch does make sense:

1. Sort your sign-ups. Accounts whose mail you want to keep receiving stay on forwarding addresses. Codes, download gates and trials move to GrabMail: type any name on grabmail.io, mixozia.com or another of the 8 public domains and read it on the page.
2. Hand out the alias. A GrabMail mailbox is public; its alias delivers to it and cannot open it. Give the alias to the form; keep the address.
3. Move a custom domain only if you want a catch-all inbox. Pointing its MX at smtp.grabmail.io makes every address on it a public inbox here, free — the opposite of a private forwarding domain. Decide which you want before changing the record.
4. Keep the extension you like. TrashMail’s right-click-to-paste add-on has no equal here yet; GrabMail’s Chrome extension is loaded by hand.

Which one, for what

The honest split is by whether you want the mail:

When to stay with TrashMail

Three situations where switching would cost you something real:

• You receive there. Newsletters, receipts and accounts you keep are a forwarder’s job. A public inbox that deletes after 5 days is not a place to receive anything you want.
• You need it private. A zero-knowledge mailbox on German servers versus a mailbox anyone can open: for anything personal, this is not a close call.
• You send under your domain. Plus lets you; GrabMail cannot send at all.
