Which one fits
Choose Poofbox Mail for
- AI agents. Claude, ChatGPT and Cursor connect over MCP and call create_mailbox and wait_for_email themselves.
- Small suites. A yearly plan from €9.99: 150 emails a day covers most sign-up and reset tests.
- Tests that read like the flow. waitForEmail() returns as soon as the email lands, with the code and best link picked out.
- EU hosting. Everything runs on servers in Germany. No ads, no tracking cookies.
Choose Mailosaur if
- You test SMS, or need email rendering previews across clients.
- Your team needs shared seats, SSO or an enterprise contract.
- You receive thousands of test emails a day across many projects.
Switching takes a few lines
Install the poofbox package, add an MCP token from the dashboard to your CI secrets, and wait for emails the same way your users receive them.
AI agents skip the package: they connect to the MCP server and call the tools directly.
email.spec.ts
import { Poofbox } from 'poofbox';
// POOFBOX_TOKEN comes from your CI secrets
const pb = new Poofbox();
const inbox = await pb.createInbox();
// …sign up with inbox.address…
const { code, link } = await inbox.waitForEmail({ subject: 'verify' });
await inbox.delete();Personal €9.99 or Pro €34.99 a year
