Read the full docs →
GET/v1/messages

List message summaries with filters.

GET/v1/messages/latest

Fetch the latest matching message with full content.

GET/v1/messages/:id

Retrieve a specific message by id.

Example request
curl -H "Authorization: Bearer <API_KEY>" \
  "https://api.plop.email/v1/messages/latest?mailbox=qa&tag=login"

Scopes

Choose the narrowest scope for each key. Mailbox-scoped keys must match the mailbox filter.

api.fullemail.fullemail.mailbox

Drop into your test suite.

Wait for an email, extract fields, assert results.

// Fetch the latest matching email
cy.request({
  method: 'GET',
  url: 'https://api.plop.email/v1/messages/latest?mailbox=qa&tag=login',
  headers: { Authorization: 'Bearer <API_KEY>' },
}).then(({ body }) => {
  const otp = body.data.textContent?.match(/\b\d{6}\b/)?.[0]
  expect(otp).to.match(/\b\d{6}\b/)
  cy.get('[data-testid="otp-input"]').type(otp)
})

Security

Secure by default.

Every mailbox is protected with explicit auth, scoped access, and predictable routing rules.

Private inboxes

Mailboxes live inside your team and require an API key.

Scoped API keys

Grant full access or lock a key to one mailbox.

Strict routing

Unknown mailboxes are rejected and never stored.

Pricing that scales with your inboxes.

Start lightweight, then unlock unlimited mailboxes as you grow.
