MailSlurp Client for Email and SMS API

MailSlurp Client is the official JavaScript and TypeScript library for interacting with the MailSlurp Email and SMS API. It enables developers to programmatically create on-demand email addresses and phone numbers without managing a mail server, facilitating sending and receiving real emails and SMS messages directly from applications or automated tests. The library is currently stable at version 17.2.0 and maintains a regular release cadence. Its key differentiator is providing a fully functional, programmatic interface to an email and SMS infrastructure, making it ideal for robust end-to-end testing of communication workflows. It supports handling attachments, setting custom timeouts for message arrival, and offers both CommonJS and ES module import patterns. The client integrates with the standard `fetch` API and allows for custom `fetch` implementations.
