# Programmatic Email API We provide a **modern, cost-effective, and compliant PaaS** for to send programmatic emails. ## What are programmatic emails? These are emails that are triggered by a computer system, typically as part of a larger workflow. For example, consider an agency that receives grant applications from members of the public. When an applicant submits a grant on your website, upon receiving the submission, your system could call our API to send out an acknowledgement email. The same could be done for sending one-time-passwords (OTPs), appointment booking confirmations, status updates emails, and so on. ## --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
