Why teams switch from Mailslurp

Built for QA teams

Mailisk is built for developers and QA teams. We provide a simple API and SDKs for the most popular testing frameworks.

Unified email & SMS

Mailisk captures inbox and SMS traffic through the same client and billing plan. You get a familiar API for both email and SMS.

Automatic waiting & retries

Mailisk search endpoints wait by default, eliminating extra polling helpers or timeout math in your tests.

Modern dashboard

Share message previews securely, inspect attachments, and replay payloads without leaving the browser.

Typed Node SDK

The official MailiskClient bundles TypeScript types, polling helpers, and retries so your test assertions stay clean.

Transparent pricing

Simple monthly plans with unlimited users and API keys. No surprise overage when you add more parallel runs.

Translate Mailslurp snippets directly

Replace waitForLatestEmail/SMs calls with Mailisk search helpers. Namespaces provide the isolation Mailslurp inboxes attempted, while keeping filters familiar.

waitForLatestEmail → searchInbox

Keep the same timeout logic and filtering you rely on today. Mailisk returns the same payload metadata with typed responses.

Mailslurp

import { MailSlurp } from "mailslurp-client";

const mailslurp = new MailSlurp({ apiKey: process.env.MAILSLURP_API_KEY! });
const inbox = await mailslurp.createInbox();

await triggerSignup(inbox.emailAddress);

const email = await mailslurp.waitForLatestEmail(inbox.id, 30_000, true);

const link = email.body?.match(/https?:\/\/\S+/)?.[0];
if (!link) {
  throw new Error("Verification link missing");
}

Mailisk

Waits automatically

import { MailiskClient } from "mailisk";

const mailisk = new MailiskClient({ apiKey: process.env.MAILISK_API_KEY });
const namespace = "ci-smoke";
const testEmail = `user+${Date.now()}@${namespace}.mailisk.net`;

await triggerSignup(testEmail);

const { data } = await mailisk.searchInbox(namespace, {
  to_addr_prefix: testEmail,
  subject_includes: "Verify your account",
});

const link = data[0]?.text?.match(/https?:\/\/\S+/)?.[0];
if (!link) {
  throw new Error("Verification link missing");
}

Mailslurp-level coverage plus modern workflows

Full payload visibility

Inspect every header, attachment, and render within Mailisk. Open sharing links for stakeholders who don't live in GitHub.

Straightforward pricing

Mailisk plans cover unlimited users and API keys with no per-inbox surprises, so scaling CI suites stays predictable.

EU-native infrastructure

All Mailisk data stays in the EU, keeping every inbox GDPR-compliant without juggling region-specific settings.

Real-world parity

Mailisk receives the exact SMTP traffic your production apps send, so flaky mocks disappear from CI.
