JetEmail gives hosting providers, software teams, and low-volume senders a practical smarthost plus API. It also adds inbound filtering, quarantine, webhooks, tracking, and credential controls from the same platform.

Explore pricingJetEmail runs its own anycast network across Sydney, Amsterdam, and New York. We operate the IP pools, the routing, the bounce handling, and the spam-filtering engine ourselves. There's no upstream relay between you and the recipient, so when we say 99.9% delivery, it's because we control every link in the chain.
Real-time IP reputation monitoring rotates senders out of poor-reputation pools automatically, and the same engineers who write the routing code answer the support tickets. When something does go wrong, we look at the actual logs, not a third-party dashboard.
Mail Baby focuses on outbound smarthost delivery. JetEmail does both. Point your MX records at us and we filter spam, phishing, and malware before they reach your mailboxes. Use the same dashboard, the same plan, and the same support team for everything that flows in and out of your domain.
For developers running multi-tenant apps and hosting providers managing customer domains, that means one vendor instead of two, and one bill instead of two. You can review SMTP logs, inbound filtering, credentials, and support from one account.
