Email Testing System We Use For Development

As a software development company owner, I emphasize the importance of security to all clients we are building projects for. Multifactor user authentication and email validation during sign-up is a must-have feature all apps and websites we create the feature.

However, since end-users will not be able to use our clients’ platforms unless they click the confirmation link in the email, it’s crucial that every registered website visitor gets a confirmation message. 

How does our team ensure a 100% sure and secure delivery of sign-up confirmation, password reset, and other emails using ASP.NET. In this post, I will elaborate on why we started using third-party email testing tools to handle ASP.NET send email and which platforms made the most difference to the team.

Why We Use Email Testing Software?

A lot of my peers in ASP.NET MVC web development are wary about using third-party testing tools, mostly due to high subscription fees and security concerns. However, in my experience, the difference these platforms make in terms of testing efficiency and message deliverability far outweighs all challenges. 

Here’s why we use email testing tools:

1. Testing gives rendering confidence

Since email designs look different depending on the browser, email client, and device a reader is using, reaching a common denominator and finding a look that’s not distorted regardless of any changes is crucial for our clients. 

Other than that, while some rendering errors are insignificant, others are impactful and can tank the letter’s readability once and for all. 

2. Validating DKIM and SPF records protects emails from being flagged as spam

As a part of the testing curve, the QA department validates the Sender Policy Framework and Domain Keys Identified Email records of a sender’s email. This powerful validation mechanism ensures that emails have lower odds of being marked as spam. 

Here’s why DKIM and SPF checks are important

3. We test image rendering

It’s no secret that images are a huge part of brand identity – they help business owners and app users build a mental link between the message and the company. However, from a testing perspective, visuals are often a pain in the neck – they can superimpose the copy, increase the loading time, occlude a link or conversion button. 

Email testing tools give the QA team a solid idea of how the images are seen on different devices, operating systems, via browser and email clients. This way, we can ensure that a display miscalculation didn’t’ get in the way of user and customer acquisition.

4. Email tools help us validate the date and time of sending

Email testing platforms help our clients compare the performance of several campaigns sent out on different weekdays or times of the day, compare the open and engagement rates, and choose the fittest schedule. Tracking ASP.NET emails manually doesn’t give developers such a bird-eye view of the engagement, leaving us less room for experimentation and optimization. 

5. We have no need to build a testing infrastructure from scratch

Since custom email infrastructure is extremely robust, we prefer to rely on solutions that offer a built-in one

At Intellipro, we acknowledge the importance of a first-rate email testing infrastructure. However, setting up a virtual inbox and an SMTP server for every project the development team is working on is time-consuming and redundant, considering the abundance of off-the-shelf tools with the fully fleshed-out infrastructure.

Software We Use For Email Testing

Since there are lots of email testing and spam checking tools, at some point, our team had to narrow the toolset down choosing only the most convenient and safest platforms for email testing. Before describing how and why we chose the solution IntelliPro is currently using, I want to list and briefly discuss the types of testing we prioritize at the company. 

  • Display testing – the way readers see our clients’ emails on different devices, using various browsers and email clients. 
  • Deliverability – whether or not our emails bounce, what types of bounces are more common (short vs hard), how much time it takes for an email to bounce back. 
  • HTML validation – ensuring that there are no missing or redundant HTML tags in the copy. 
  • Sender reputation – monitoring open rates, spam complaints, and user engagement. 

Ideally, we were looking for a tool that would offer the team insights on all of these testing activities, would be easy-to-use and well-supported. After trying both small-scale and large-scale platforms, we’ve eventually found the middle ground (for us, it’s the Mailtrap testing platform).

Why we chose Mailtrap

  • There’s a well-built email infrastructure – a configured SMTP and a shared inbox our entire team can use. 
  • A stripped-down list of features – there are no redundant tools, only those our team needed to ensure safe email delivery and right interface display. 
  • HTTPS and TLS encryptions – as a development team, we take security seriously and make sure our testing tool of choice has an established framework as well. 
  • A fully configurable environment for email functionality development using C#.
  • All projects are well-organized, we enjoy being able to separate campaigns into different folders. 

Conclusion

At the end of the day, we’ve come to rely on email testing tools a great deal. If you are a software developer who wants to facilitate the process of email infrastructure setup and make sure all messages you send to your users reach their destination and look their best, using third-party tools is the fastest and non-resistant way to excel at email testing while staying dedicated to other projects.
