“Email me whenever someone signs up or makes a payment on my website.” “Send a welcome email to every new signup.” “Send this newsletter to my customer list.” # EPST — email for your apps and AI agents. You get your own email domain, REST API and MCP access with one API key, and a generous free plan. The idea is simple: spend less time handling repetitive email tasks and more time building.
