AI identifies the right reviewers, generates PR summaries, and sends email requests with estimated review time — smarter than GitHub's defaults.
Pull requests sit unreviewed for days because the right reviewers aren't notified effectively. GitHub's default notifications are noisy — reviewers receive too many requests and can't prioritize. The result is slower development velocity, merge conflicts from stale PRs, and frustrated developers waiting for approvals.
MultiMail's AI agent analyzes PRs to identify the most relevant reviewers based on code ownership and expertise, generates concise summaries highlighting key changes, and sends targeted email requests with estimated review time. Autonomous mode ensures instant delivery.
Your CI/CD system sends a webhook when a PR is created or updated. The AI agent analyzes the diff to understand the scope and nature of changes.
The agent determines which developers have expertise in the affected code areas using CODEOWNERS, commit history, and team metadata from your contacts.
The agent writes a concise summary of key changes, potential risks, and estimated review time so reviewers can prioritize effectively.
Using send_email with autonomous oversight, the agent delivers personalized review requests to each identified reviewer with the summary and direct PR link.

}Use MCP tools to send PR review requests and track response.
Targeted notifications to the right reviewers with clear summaries help PRs get reviewed in hours instead of days.
Estimated review time and risk assessment help reviewers decide which PRs to tackle first, improving overall development velocity.
Only relevant reviewers are notified, unlike GitHub's default which can notify entire teams. Less noise means each notification gets more attention.
Review requests stay in the reviewer's inbox until acted upon, unlike Slack messages or GitHub notifications that scroll away in busy channels.
