Email testing made simple.
Designed for developers.
Mailisk is a blazingly fast email testing platform focused on simplicity and privacy.
Get unique subdomains and gain access to unlimited email addresses.
How does it work?
Send an email to your Mailisk address – we handle it
You can then access it via the API
const { MailiskClient } = require("mailisk");
const namespace = "mynamespace";
// create client
const mailisk = new MailiskClient({
apiKey: "YOUR_API_KEY",
});
// receive email
const result = await mailisk.searchInbox(namespace);
console.log(result);describe("Test receive email", () => {
const namespace = "mynamespace";
const testEmailAddress = `test@${namespace}.mailisk.net`;
it("Gets an email", () => {
cy.visit("example.com/test-email");
cy.get("#email").type(testEmailAddress);
cy.get("form").submit();
cy.mailiskSearchInbox(namespace, {
to_addr_prefix: testEmailAddr,
subject_includes: "testing",
}).then((response) => {
expect(response.data).to.not.be.empty;
const email = response.data[0];
cy.log(email)
});
});
});{

Frequently Asked Questions
What are namespaces?
Namespaces are unique subdomains under which you can receive emails. Every free user gets one random namespace, paid users can choose custom namespaces.An example of a namespace is hello@{namespace}.mailisk.net. You can read more about namespaces here.
What happens when a namespace expires on the free plan?
On the free plan, namespaces are set to expire after one month. After expiration, free users will have to create a new random namespace. Once a namespace expires, all associated emails and data are deleted.
What happens if I go over the monthly limit?
Paid plans can have temporary egress without any hard limits. If you frequently exceed your monthly usage we will reach out.
What email limitations are there?
The maximum email size is 10MB. Emails larger than this are rejected. If you feel your use case needs a higher email size limit, please reach out.
Can I send outbound emails?
Yes, Mailisk supports sending emails using our Virtual SMTP servers. The emails can be sent to any valid mailisk address within the same namespace.
