Extract OTPs in milliseconds.
Store nothing.
Direct IMAP socket connections. In-RAM MIME decoding. Heuristic code extraction. The session ends before a traditional client finishes syncing.
Built for automation,
not for humans
Email clients render stylesheets and sync gigabytes. This is a precision instrument: open a socket, read the envelope, extract the code, vanish.
Sub-second pipeline
Selective IMAP SEARCH + FETCH for headers and plaintext parts only. Pre-compiled regex heuristics run in volatile RAM — no attachments, no sync queues, no waiting. Typical end-to-end: under 180 milliseconds.
Zero persistence
Credentials, bodies, attachments — processed in memory, purged on response. Nothing touches disk. Ever.
Thousands of mailboxes
Concurrent workers poll at scale without socket starvation or rate-limit penalties.
IMAP diagnostics
TLS handshakers and health analyzers catch upstream issues before production does.
Auto-discovery
Provider intelligence maps hosts, ports and SSL settings for M365, Google Workspace and custom domains.
Four tools. One workflow.
From manual testing to headless CI — pick the surface that fits.
Bulk Reader
Paste accounts or upload a .txt, poll every inbox live, get OTPs in one unified newest-first feed.
Open Reader →2FA Generator
TOTP codes from your secret key. Live code, countdown, next-code forecast — 100% in your browser.
Generate →Open Inbox
Visual webmail: folders, search, one-click OTP copy, random identity generator for test signups.
Open Inbox →Developer API
GET /api/otp for plaintext codes, /api/latest for JSON, /api/read_code for combined reads. UUID-scoped, rate-limited, documented.
Read Docs →Drop it into your pipeline
Poll for the code. That's the whole integration.
Against the old way
What changes when you stop syncing mailboxes.
| MA Digital Reader | Standard IMAP | Legacy POP3 | |
|---|---|---|---|
| Handshake latency | Sub-180ms | 600–1500ms | 800–2000ms |
| Data retention | 0 bytes, RAM only | Persistent sync | Disk download |
| OTP extraction | Automatic | Manual parsing | None |
| Bandwidth per check | Headers + plaintext | Full MIME | Entire queue |
| Bulk mailboxes | Concurrent | Sequential | Sequential |
Where it earns its keep
Four workflows, one backbone.
E2E signup testing
Playwright and Cypress pull codes programmatically milliseconds after signup. No flaky webmail UIs.
Staging cleanup
Parallel expunge wipes thousands of disposable test inboxes without hammering the server.
Socket diagnostics
Verify cert chains and STARTTLS negotiation before email services hit production.
Secure handoff
Encrypted ephemeral URLs let remote testers read streams without ever seeing passwords.
