Don’t worry about buying and managing hardware and software. Use our scalable messaging platform to send as many (or few) emails as you need.

Access our service via an API, not a web console.

Advanced authentication scheme; no one will sully your reputation.

While no ESP can ever guarantee that an email will get delivered, we have over 10 years of email deliverability experience and take advantage of adaptive deliverability, domain keys, white listing, ISP relationships, etc to maximize the chances that your email will be delivered.
