Why teams switch from Mailosaur
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.
Port Mailosaur flows in minutes
Line up the Mailosaur function you use today and drop in the identical Mailisk call. Filters and response shapes stay familiar, so the migration focuses on find-and-replace rather than rewrites.
Email verification & onboarding
Mailisk searchInbox mirrors Mailosaur filters like sentTo, subject, and wait behavior—only with namespace scoping instead of server IDs.
Mailosaur
import MailosaurClient from "mailosaur";
const mailosaur = new MailosaurClient(process.env.MAILOSAUR_API_KEY);
const serverId = process.env.MAILOSAUR_SERVER_ID;
const testEmail = "user@examplemailosaur.com";
const result = await mailosaur.messages.search(serverId, {
sentTo: testEmail,
subject: "Verify your account",
errorOnTimeout: true,
});
if (!result.items.length) {
throw new Error("Email never arrived");
}
const match = result.items[0].text.body.match(/https?:\/\/\S+/);
const verificationLink = match?.[0];Mailisk
Waits by default
import { MailiskClient } from "mailisk";
const mailisk = new MailiskClient({ apiKey: process.env.MAILISK_API_KEY });
const namespace = "checkout-tests";
const testEmail = `user@${namespace}.mailisk.net`;
const { data } = await mailisk.searchInbox(namespace, {
to_addr_prefix: testEmail,
subject_includes: "Verify your account",
});
if (!data.length) {
throw new Error("Email never arrived");
}
const match = data[0].text?.match(/https?:\/\/\S+/);
const verificationLink = match?.[0];Mailosaur-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.
Real-world parity
Mailisk receives the exact SMTP traffic your production apps send, so flaky mocks disappear from CI.
