Program Your Notifications: How MailFlow API Calls Give Developers Full Control Over Critical Emails
About
As a developer, you probably hate being at the mercy of email. Alerts pile up, OTPs get lost in spam, and confirming actions means switching contexts or writing yet another integration.
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
