Send transactional email with tenant-level abuse control
Let your users, customers, and AI agents send transactional email through your platform without one bad sender risking your whole account. MailChannels gives every tenant its own identity, policies, and rate limits, and owns the abuse ops generic APIs leave to you: complaint handling, bounce feedback, and safe suspension. Battle-tested at ~100M messages/day for hosting providers. Not for newsletters or cold outreach. Built for platforms with downstream senders.
MailChannels Email API enables platforms to send transactional emails while providing tenant-level abuse control, ensuring that individual users do not jeopardize the entire account. It includes features like identity management, policy enforcement, and abuse handling, and is optimized for high-volume environments, processing approximately 100 million messages daily.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
