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.

Hi Product Hunt, I’m Ken, CEO of MailChannels.
If your product sends email on behalf of customers or their AI agents, their behavior becomes your risk. One tenant sends phishing or generates enough complaints to damage your reputation, and suddenly every other customer on your platform has trouble delivering password resets and other important messages.
MailChannels has spent 20 years managing this problem for web-hosting providers, where thousands of independent senders share the same infrastructure. A large hosting customer recently told me that if they moved their email elsewhere, they expected to be blocked.
The MailChannels Email API brings that infrastructure to developers. Give each tenant or agent its own sender identity, rate limits, and policies. If one sender misbehaves, you can suspend that tenant without taking everyone else offline. We process bounce and complaint signals and deliver them to you through webhooks, so you can manage sending without building your own abuse operation.
It’s designed for transactional and agent email. There’s a free tier, and Product Hunt users get 30% off the first year of a paid plan.
Try it at docs.mailchannels.com. I’ll be here today to answer questions—especially from anyone who has had one bad tenant put their whole sending operation at risk.
