HTTP, SMTP, virtual, and expiring inbox types
Provision inboxes that match the job, from no-send capture and short-lived QA addresses to long-lived operational mailboxes.
Provision real email addresses with API control
Create inboxes per user, workflow, or test run. Receive, parse, and assert messages without shared mailboxes or manual checks.
Trusted by top companies worldwide
Built for production workflows
MailSlurp features for programmable email addresses
Create the inbox type you need, control it through API and SMTP/IMAP, and keep message handling tied to the workflow that owns it.
Explore
Custom domains, aliases, and catch-all addressing
Create branded inboxes and masked addresses on verified domains while keeping routing and ownership under API control.
Send, receive, search, and wait through one inbox surface
Use API, SMTP, and IMAP access together with wait functions, search endpoints, and latest-message helpers instead of stitching together separate tools.
Webhooks, rules, and extraction-ready message data
Attach webhooks, rulesets, and parsing helpers to each inbox so inbound mail can drive testing, automation, and downstream systems immediately.
Create addresses on demand
Generate random, expiring, or custom-domain inboxes with tags and metadata for deterministic routing.
Combine API automation with dashboard visibility
Let engineers automate mailbox lifecycles while QA and support inspect message state in shared workspaces.
Developer integration
Use inbox APIs, SMTP, and webhook events in the same workflow
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
