Case Study: How a Custom Email Validation Application Boosted Deliverability

I. Introduction

Our client was a marketing & advertising company experiencing high bounce rates and poor email deliverability. The services they were using previously had stopped working, and the cost of the SaaS applications on the market that offered similar functionality was too high and didn't fully solve their issues.

To address these challenges, we developed a custom email validation application specifically tailored to their needs.

II. Background

Email validation is an important aspect of business and marketing, as it helps ensure that emails are delivered to the intended recipient and are not marked as spam or bounced back. Traditional email validation methods, such as simple syntax checks and domain checks, are limited in their ability to accurately validate an email address.

Our client needed a more reliable and effective solution to improve their email deliverability and reduce bounce rates.

III. Solution

We developed a custom email validation application that utilizes SMTP validation along with all the usual email and domain validation strategies. The application first checks for correct syntax, domain availability, and the presence of a valid mail server for the domain. It then checks for disposable or temporary email addresses, which are often used to bypass email validation systems. Finally it checks if the email address even exists on the server and if it does, if the domain is using a catch-all.

Some key features and benefits of our custom email validation application include:

• High accuracy: Our application has a high rate of correctly identifying valid and invalid email addresses, helping our client improve their email deliverability and reduce bounce rates.
• Real-time data: Our application uses real-time data to validate email addresses, ensuring that the results are up-to-date and relevant.
• Customized to client needs: Our application was developed specifically for our client's needs, allowing them to choose the level of validation they required and ensuring that the application fit seamlessly into their workflow.
• Cost-effective: Compared to SaaS applications on the market that offer similar functionality, our custom email validation application was more cost-effective for our client.

IV. Case Study

Our client, a marketing & advertising company, had been struggling with high bounce rates and poor email deliverability. They had been using a variety of email validation services, but these had all stopped working for various reasons. The cost of the SaaS applications that offered the functionality they needed was too high, and they were not confident that these applications would fully solve their issues.

We worked with the client to understand their specific needs and developed a custom email validation application to meet these needs. The application was integrated into their email marketing workflow, and the client was able to choose the level of validation they required.

After implementing the custom email validation application, our client experienced a significant improvement in their email deliverability and a reduction in bounce rates. They also reported an increase in customer engagement, as their emails were reaching their intended recipients more reliably.

There were a few challenges faced during the implementation of the custom email validation application. One major challenge was avoiding being added to lists like spamhaus. Even though we are not sending email, this particular type of validation is disliked by ISPs. We found a volume and speed of validation that has been working for a few months now. We also provided a way to do less aggressive validation for larger or less important lists.

V. Conclusion

In summary, our custom email validation application helped our client improve their email deliverability and reduce bounce rates, resulting in increased customer engagement. The application was tailored to the client's specific needs and was more cost-effective than other solutions on the market. While there were a few challenges faced during the implementation, we were able to work closely with the client to address these issues and ensure a successful implementation.
