Mailflow solves both with a single API call.

The Closed-Loop Magic

Use POST /api/v1/emails:

• Send a real, authenticated email from your chosen @mailflow.cc address (e.g., no-reply@mailflow.cc).
• Because the email originates from your workspace mailbox, Mailflow’s forwarding rules automatically apply.
• Result: The recipient gets a proper email, and you (or your team) instantly receive the content in Telegram, Discord, Slack, WhatsApp, or via webhook.

One API call → two outcomes.

Practical Examples

• User password reset → send reset link via /emails → you see confirmation in private Telegram (great for monitoring abuse).
• Order confirmation → real receipt email + instant Discord ping in #sales.
• Critical error log → /emails to admin + immediate Slack alert.

Superior to Slack’s Built-in Email Integration

Slack’s email-to-channel feature works, but:

• No isolation between projects
• No WhatsApp/Telegram support
• No programmatic sending
• Limited formatting and no real outgoing email

Mailflow alternatives beat it by offering:

• Dedicated @mailflow.cc per project/channel
• Multiple chat destinations
• Full API for outgoing + forwarding for incoming
• Webhook support for custom tools

Bonus: Never Miss Important Emails

All critical addresses forward to dedicated Mailflow workspaces → aggregated and pushed instantly → zero chance of burial in a noisy inbox.

For $99 lifetime (or $3.99/month) you get 30 isolated workspaces, real outgoing email capability, and the closed-loop notification system every solo developer dreams of.

Stop paying for separate email + chat notification services.
