Alias controls

MailSlurp features for masked addresses and controlled forwarding

Create public-facing addresses that stay stable while the hidden destination, forwarding path, and reply behavior remain under API control.

Create masked alias addresses with hidden destinations

Publish an alias email address without exposing the real inbox or system endpoint behind it.

Explore

Verify and rotate forwarding targets safely

Confirm destination ownership before activation and change the hidden target later without changing the public address.

Explore

Control forwarding and reply threading behavior

Keep forwarded mail and replies attached to the right workflow instead of letting mailbox-side forwarding break the conversation path.

Explore

Manage alias lifecycle through API and dashboard

Create, disable, rotate, and review aliases programmatically or through shared operational tooling when ownership changes.

Start with SDK helpers for inbox creation and message waits, then move into event-driven routing when the workflow expands.

  • Generated SDKs for major languages
  • API + SMTP + IMAP support where needed
  • Docs-backed patterns for inboxes and message assertions
