Poofbox Mail vs MailSlurp
A simpler MailSlurp alternative
for AI agents and email tests.
MailSlurp is a broad email and SMS API that can also send mail. Poofbox Mail does one thing well: disposable, receive-only inboxes that wait for the verification email and hand back the code or link, for your test suite or your AI agent.

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 MailSlurp if
- You need to send email from your test inboxes, or test SMS.
- A free plan with monthly limits covers your volume.
- You rely on their wider feature set: webhooks, forwarding, many SDKs.
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
