What if your inbox wasn’t just passive storage — but something you could program directly from your code?

MailFlow makes that possible with simple, powerful API calls that let you both simulate incoming emails and send outbound ones — turning email into an active part of your automation stack.

Built for high-stakes scenarios (DevOps alerts, 2FA codes, payment confirmations, support tickets), MailFlow delivers critical messages in under 5 seconds to Telegram, Slack, Discord, WhatsApp — or your own webhook — while AI summarizes long emails and pulls out key details like verification codes.

The killer feature for devs? Two straightforward API endpoints that close the loop.

Push Custom Alerts with /notifications

Need to trigger a real-time notification from your monitoring script, CI pipeline, or serverless function?

One POST to /api/v1/notifications simulates an incoming email — MailFlow processes it instantly: AI summarizes, extracts OTPs if present, and fans it out to your connected chat apps.

Example use case: Your uptime monitor detects downtime → API call pushes the alert → Telegram receives an AI-condensed version like “Server down at 2:14 AM PST – CPU spike detected.”

No SMTP hassle, no fake email accounts — just code that talks directly to your notification hub.

Reply or Follow Up with /emails

The other direction: send emails from your MailFlow workspace address using /api/v1/emails.

Received an alert via Telegram? Your bot or script can reply automatically — confirm receipt, escalate to on-call, or send a status update — all via one API call.

Real-world wins:

• CI/CD failure → push alert → auto-send follow-up email to team with logs attached
• Payment webhook confirmation → API call sends thank-you + receipt to customer
• Security alert → acknowledge via chat → API emails detailed report to compliance

Why It’s a Developer Favorite
