Email deliverability testing, and QA testing web apps with multiple account permissions, are critical aspects of software development and Quality Assurance (QA). Although disposable email websites and gmail addresses are a common choice for this task, they present several significant drawbacks for enterprises. This article will detail the advantages of using dedicated email deliverability platforms like Mailsac instead.
Disposable email platforms typically make all emails public. These websites are frequently crawled by scammers to acquire sensitive information.
Disposable email services often lack robust security measures, exposing sensitive test data. This lack of security can compromise the integrity of testing and risk breaches of confidential information. They rely on security through obscurity – random email addresses that are hopefully unguessable.
Disposable email providers typically do not have Information Security and Assurance programs, and cannot pass a Vendor Risk Assessment.
The terms of service for disposable email services are often unsuitable for professional development and testing contexts. They can include problematic clauses and offer limited protections for users, which isn’t ideal for businesses. The terms and privacy policies tend to be non-negotiable.
Disposable email services often lack capabilities for Business-to-Business (B2B) interfacing. This limitation can hinder the integration of these services into larger, automated testing suites, significantly limiting their usefulness in professional testing scenarios.
Disposable email services are often slow and lack reliable uptime. These performance issues can introduce unnecessary delays into the testing process and create uncertainties around the reliability of test results. If an email was delayed, it can be hard to know if it was on your end, or theirs.
Mailsac, as a dedicated email deliverability platform, provides a solution to these limitations and offers considerable advantages for professional QAs and software devs.
Mailsac prioritizes security, providing secure paid private inboxes and whole subdomains for testing.
You can test your application’s email functionality without risking sensitive data being leaked or public, or sold to a data broker.
Mailsac offers business-friendly terms of service, custom terms, P.O.s, multiple users, SSO and other features designed with the needs of professional QAs and software developers in larger companies with legal and security requirements. This provides a more suitable environment for business operations and testing.
Mailsac provides powerful REST APIs, webhooks, and web sockets for integrating into CI/CD and workflows. Companies frequently integrate mailsac seamlessly into their automated testing suite. Using a consumer disposable provider often results in unexpectedly failed builds. Using a professional provider gives you comprehensive and efficient testing and enables continuous deployment.
Mailsac has high uptime and quick API and UI performance, ensuring a smooth and reliable email testing process. We believe performance is a feature.
When you are testing a web application, you can use email addresses that are private to your Mailsac account to sign up for your app. Then share those inboxes with your teammates. For example, you may be testing a web app with two RBAC roles – administrator and readonly user. Each can have a unique mailsac email address. Your web app sends a sign-in link via email. All team members can access it (using mailsac’s multi-user or SSO feature). And since it’s not disposable email, the sign-in link to your app’s dev environment won’t be public.
While disposable email services may appear convenient, they come with considerable drawbacks for professional QAs and software devs. They can be against company policies because they may leak proprietary business information. Mailsac, with its robust features and focus on business needs, provides a far more effective solution for email deliverability testing.
The importance of Quality Assurance (QA) testing in software development and operations cannot be overstated. It ensures the product or system performs as expected, minimizing the risk of unexpected failures in production environments. A crucial aspect of QA testing involves testing email deliverability. This article will focus on how to use Mailsac, a leading tool in email testing, to execute this task effectively.
Mailsac is a service providing temporary, “for-test-only” email addresses that can be used for testing and development purposes. Mailsac’s uniqueness lies in its capability to accept emails sent to any unique, auto-generated email addresses under its domain, thus eliminating the need for pre-generating email addresses or setting up a dedicated testing email server.
Email deliverability testing is vital to ensure emails are correctly dispatched from your application and are appropriately received by your users. Mailsac offers the flexibility to test various email formats and content, inspect the received emails, and verify they are correctly formatted and contain the correct data. This helps mitigate common issues such as emails being marked as spam, lost emails, or broken email formats.
Let’s delve into the steps to conduct QA testing for email deliverability using Mailsac.
First and foremost, you need to create a Mailsac account. Visit the Mailsac website and follow the sign-up instructions.
Next, send emails from your application to any addresses on the mailsac.com domain. Mailsac is designed in such a way that you don’t need to pre-generate the email addresses. Just decide on the address you want to use and send the email. The inbox will be created automatically when an email is received.
You can send the emails from anywhere, too – personal or work addresses, fake senders, CLI tools, software applications – without a separate sending gateway.
After sending the emails, you can verify their delivery in the Mailsac interface. Here, you can view the received emails, check their contents, and confirm they are correctly formatted. Mailsac also enables you to check if attachments are included correctly using the Unified Inbox or API, and whether the links and images in the email are functioning properly.
For more sophisticated or comprehensive testing, Mailsac offers a robust JSON REST API and Web Socket API. This empowers you to automate the process of sending emails, checking their delivery, and verifying their contents. These API calls can be integrated into your automated testing suite, enabling you to conduct in-depth email deliverability tests as a part of your regular testing process.
Mailsac presents a powerful and versatile method to test email deliverability as a part of your QA process. It allows you to send emails to any address on its domain, and the inboxes are created automatically when an email is received. By integrating Mailsac into your QA testing, you can significantly enhance the quality and reliability of your email notifications, thus offering a better user experience. Sign up and start receiving email in seconds.
Mailsac has rolled out a new API endpoint feature, dubbed “inbox filter.”
It limits email messages using the to
, from
, and subject
fields. Say goodbye to the conventional OR logic of /api/inbox-search
and embrace the power of logical AND.
The /api/inbox-filter
API endpoint accepts the following optional query parameters:
This endpoint delivers results only when at least one query condition is specified, otherwise, expect a 400 error. The response is capped at 100 results, so adjust your query or prune your account accordingly.
To illustrate the usage of the /inbox-filter
API endpoint, here’s a JavaScript unit test using Mocha and Axios:
const axios = require('axios');
const assert = require('assert');
describe('Inbox Filter API Endpoint Test', () => {
it('should return filtered messages', async () => {
const mailsacApiKey = 'your-api-key-here';
const endpoint = 'https://mailsac.com/api/inbox-filter';
const andSubjectIncludes = 'Important';
const andFrom = 'johndoe@example.com';
const andTo = 'janedoe@example.com';
const response = await axios.get(endpoint, {
headers: { 'Mailsac-Key': mailsacApiKey },
params: { andSubjectIncludes, andFrom, andTo },
});
assert.strictEqual(response.status, 200);
assert.strictEqual(Array.isArray(response.data.messages), true);
response.data.messages.forEach((message) => {
assert.strictEqual(message.subject.includes(andSubjectIncludes), true);
assert.strictEqual(message.from[0].address.includes(andFrom), true);
assert.strictEqual(message.to[0].address.includes(andTo), true);
});
});
});

As a business manager in a software company, you understand the importance of effective communication with your customers. Email remains a critical channel for connecting with your audience, but many organizations overlook the importance of thoroughly testing their email sending capabilities. Failing to test your outbound email systems can lead to embarrassing mistakes, decreased customer satisfaction, and even regulatory consequences in certain industries. In this blog post, we’ll explore the downsides of neglecting email testing and explain why it should be a priority for your business.
One of the most common issues businesses face when not testing their email sending capabilities is accidentally sending duplicate or incorrect emails. This can happen due to software bugs, incorrect configuration, or simple human error. When customers receive multiple copies of the same email or emails containing inaccurate information, it can create confusion, erode trust, and damage your brand reputation. By investing in proper email testing, you can catch these errors before they reach your customers.
Email personalization is essential for connecting with customers on a deeper level. However, without proper testing, you may encounter issues like incorrect name insertion or the use of outdated customer data. These mistakes can make your emails appear unprofessional and impersonal, undermining your efforts to build strong relationships with your customers. Email testing can help ensure your personalization efforts are successful and your customers feel valued.
When your email sending capabilities are not tested thoroughly, there’s a risk of failing to send important notifications to customers. This can include transaction confirmations, account updates, or even password reset emails. Delayed or missing notifications can lead to customer frustration, increased support requests, and potential security issues. Implementing a comprehensive email testing strategy can help ensure your customers receive timely and accurate notifications.
Email deliverability is crucial for ensuring your messages reach your customers’ inboxes. If you don’t test your email sending capabilities, you may encounter issues like high bounce rates, being marked as spam, or being blocked by email service providers. These problems can severely impact your email marketing campaigns and customer communication efforts. Proper email testing can help you identify deliverability issues and address them before they harm your business.
In certain industries, companies are required to send timely and accurate notifications to customers, such as financial services or healthcare. Failing to meet these requirements due to untested email systems can result in regulatory consequences, including fines or legal actions. By prioritizing email testing, you can ensure compliance with industry-specific regulations and avoid potential penalties.
As a business manager, it’s essential to recognize the importance of thoroughly testing your email sending capabilities. Neglecting this critical aspect of your communication strategy can lead to various issues, including duplicate emails, personalization mistakes, missed notifications, deliverability problems, and regulatory consequences. By investing in proper email testing, you can ensure your messages are accurate, professional, and effective in reaching your customers.
