One developer against spam.
Mailiy is built in Düsseldorf by Christian Gudermann. We believe your main inbox should belong to you — and that anti-spam shouldn't mean "sell your data to three third parties".
Manifesto
We build Mailiy because in 2026 the internet still demands an email address before letting you download a PDF, watch a demo, or open a whitepaper. A disposable mail should not be a grey-zone hack — it should be an obvious privacy option.
We don't log what you do. We don't sell your mails — they sit in Postgres until the mailbox expires, then get deleted along with every attachment. We don't require accounts. We believe that should be the norm.
The disposable-mail landscape in 2026 is surprisingly thin: a handful of tools from the early 2010s that never updated their UI, and a few larger providers that now run on ads and trackers. We wanted to build a disposable mail we would actually use ourselves — fast, ad-free on the inbox view, with a REST API that does not live behind a paywall.
Privacy as the default means specifically: no IP logging alongside your mailboxes, no third-party scripts on the inbox page, no selling of receive-data to CRM vendors. Incoming mail sits encrypted in Postgres until the mailbox reaches its TTL, then gets irrecoverably deleted along with all attachments. There is no warm backup path — what the 60-second sweep removes stays removed.
Technically Mailiy is intentionally small: Node with the smtp-server package accepts incoming mail, BullMQ decouples SMTP ingest from processing, Postgres is the only data store. No S3 mirrors, no mail-forwarding service in between, no third-party webhook provider. Everything runs on one machine in Frankfurt under GDPR — which keeps the architecture surveyable and the privacy claims verifiable.
About us as a team there is not much to say: one developer, one small concern, one mailbox in Düsseldorf. Mailiy launched as an Open Beta because we want to communicate the product to its users honestly — paid tiers are available, but Free stays free forever, because a disposable mail loses its point otherwise.
