Make Your Apps Talk to Your Inbox: MailFlow’s API Calls Turn Emails into Programmable Notifications
About
Tired of your monitoring scripts, payment gateways, or internal tools sending alerts that get buried in email? Or having to manually reply to confirmations because your system can’t “talk back”?
Most email tools let you receive or send — but very few let you program both directions effortlessly. That’s where MailFlow changes the game.
MailFlow is built for high-stakes, time-sensitive emails: OTP codes, DevOps alerts, support tickets, order confirmations. It delivers them in <5 seconds to Telegram, Slack, Discord, WhatsApp — or anywhere via webhook — while AI summarizes long messages and extracts critical info like verification codes.
But the real superpower for developers? API calls that make your inbox programmable.
1. Simulate Incoming Emails with One POST Call
Need to test a notification flow? Or push a custom alert from your backend/serverless function directly into the MailFlow pipeline?
Just use the /api/v1/notifications endpoint:
Bash
curl -X POST https://mailflow.cc/api/v1/notifications \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"workspace_id":"your_workspace","subject":"Server Down!","body":"CPU at 99%..."}'
Once sent, MailFlow treats it like a real incoming email: AI summarizes it, extracts key details if configured, and instantly pushes the result to your connected Telegram bot, Slack channel, Discord thread, or even a webhook URL.

No more fake email generators or complicated SMTP setups — just a clean API call and your alert lands where you actually look.
2. Send Emails Programmatically from Your Workspace
The loop closes with /api/v1/emails: send real outbound emails from your MailFlow workspace address.
Got feedback via webhook or Telegram reply? Your script can instantly reply with confirmation, escalation, or even auto-generated reports — all via one simple POST.
Perfect for:
- Automated support acknowledgments
- CI/CD failure follow-ups
- Payment gateway confirmations
- On-call escalation replies

Why Developers Are Switching
- Real-time delivery (<5s) to chat apps you already check constantly
- Built-in AI: long email summaries + OTP/code extraction
- Multiple isolated workspaces for dev/staging/prod separation
- Free tier includes API access (100 items/month) — Pro just $3.99/mo for serious volume
Whether you’re building internal tools, monitoring dashboards, or customer-facing automations, MailFlow’s API calls turn passive email into an active, programmable part of your stack.
