Connect your Office 365 mailbox, describe what you care about in plain English, and MailJoin will alert you the moment a matching email arrives — via SMS, Slack, or more.
How it works
Authenticate with your Office 365 account in seconds. MailJoin only reads messages to match your rules — no email content is stored permanently.
Write a plain-English description like "invoices over $5,000 from vendors" or "urgent support tickets from key customers". Our AI handles the matching.
Receive alerts through your preferred channel the moment a match is found — SMS, Slack, webhook, or email — wherever you actually pay attention.
Features
Uses OpenAI or Anthropic to understand intent, not just keywords. Works even when senders phrase things differently each time.
Connects directly to your Microsoft 365 mailbox via OAuth. No IMAP credentials or app passwords needed.
Notify via SMS, Slack, or webhook. Configure per-rule so critical emails hit your phone while others post to a Slack channel.
New emails are evaluated within seconds of arrival using background queue workers, so you never wait for a scheduled check.
Create as many notification rules as you need. Each rule has its own description, match criteria, and notification channel.
OAuth tokens are encrypted at rest. Two-factor authentication is available on your account. No email content is stored after matching.
