The art of email address validation

When I first encountered the problem of validating email addresses, it was quite an exciting moment in the workplace - imagine that. At the time, my team was working on launching an important advertising campaign and everything was going well until the first reports arrived. Imagine, we saw a delivery rate of just 55%! This was a real blow: our hard-earned subscribers simply did not receive their letters. Have any of us ever thought about how important it is to check email addresses before sending?

According to my observations, one of the most common mistakes is insufficient address validation . I decided to understand the situation and try to find a solution. By applying a few simple steps, our deliverability rates increased dramatically.

1. Analysis of the current database 📊. I started by conducting a thorough analysis of the existing database of email addresses. I used validation services to identify invalid addresses. The results were shocking: about 20% of addresses were inactive or contained errors!

2. Eliminating problematic addresses 🗑️. After validation, we removed all invalid addresses. This turned out to be a real find! By reducing the list of subscribers, we significantly increased the chances that our letters will reach real customers.

3. Checking the readiness of new addresses ✅. Each new subscriber is now verified at the registration stage. Why take the risk when you can eliminate potential delivery problems in advance?

The feedback from team members after implementing these strategies was amazing: “I didn’t know it could do so much.” influence our work!" - said one of the colleagues. Indeed, increasing open and click-through rates step by step pulled our company out of the depths of doubt.

According to statistics, 75% of companies that ignore email address validation face problems of overspending on marketing emails that simply do not reach customers. While well-executed validation can save money and optimize marketing efforts.

I am more confident than ever that effective email validation is the foundation of a successful digital strategy. After all, in a world where every dollar counts, is it worth the risk of your messages simply not getting through?

In this context, remember: a quality database isn't just about numbers, it's really about your customers. So where do you want your base to be a year from now? Use validation so that your addresses are not just notes in a notebook, but real guides to the world of your valuable offers!

Steps to validate email addresses

Address validation: when and why it is necessary

When it comes to address validation, I involuntarily recall one case from my practice, which became a real lesson for me. It was a time when I was working on a large marketing campaign for one of my clients. We have collected an impressive database of addresses and, frankly, I did not pay enough attention to checking them.

💡 In the process of preparing for the mailing, I discovered that some addresses were rejected by postal services and not one, but ten of them turned out to be non-existent! It came as a shock. How could I miss this?! “You don’t want your letters to vanish into thin air, right?” — I asked myself this question. Did the team own the quality of the data collected? It immediately became obvious that without subscriber validation the work would not have been successful.

At that time, I didn’t think about the mistakes that were made when entering addresses. It turned out that many users made typos when entering their data into the subscription form, and some even used disposable email addresses. Also, when we collected data from paper questionnaires, the number of invalid addresses simply went off scale - manual filling contributed to errors. Everyone thinks that they have everything under control, but in reality this is far from the truth!

🔥 After the first bad experience, I took the process of address validation more seriously. I started implementing email verification directly in the registration form and even used third-party validation tools. Once I found it was effective, I started getting a cleaner base. Research shows that companies that validate their addresses can avoid up to 30% of errors associated with invalid addresses.

Then I realized that checking addresses before any mailing is not just a whim, but a real necessity. 💼 After analyzing the situation, I came to the following conclusions:

• It is imperative to check the database before sending, especially if the mailing has not been carried out for many months.
• Verifying addresses collected without double opt-in is important because this category of users is more susceptible to entering invalid data.
• If the database is older than a year and there have been no mailings on it, I strongly recommend validating it, because many users may simply forget about us.

As a result, having acquired the skills of checking addresses, I not only increased my reputation as a specialist, but also helped the client avoid financial losses and remain with a clear conscience. It wasn't easy, but I was glad that I was able to change my approach.

Basic steps for validating addresses

As a result, address validation is not only a necessity, but also an opportunity to improve business efficiency.

Address validation methods

I always believed that Writing addresses correctly is not just a detail, but a true art. When I first encountered problems with database validation in one of my projects, it became obvious to me how important it is for running a business. We sent out a mailing and the number of invalid addresses exceeded all expectations. The messages were entirely in the spirit of “the address does not exist” or “the domain is inactive.” It was like a bolt from the blue!

Since then, I have implemented several techniques that have significantly improved the quality of our data. Here's what I found out:

Syntax and typo checking 🔍

Many people don’t think about how difficult it is to enter an address correctly . The username may contain typos. For example, the address "gmail.cm" instead of "gmail.com" is such a trifle, but it can lead to your message being lost forever. We have created a system where an attentive validator automatically detects such errors, sending corrected data to the database.

MX record verification 📧

Validation programs must check MX records and the presence of a mail server for the specified domains. I set up regular checks and imagine our surprise when we realized that more than 15% of our database had incorrect MX records. Of course, without them, mail simply could not reach the addressee.

Role-based addresses and spam traps 🚫

While working on the project, I learned about the risks associated with role-based addresses, such as "admin" or "postmaster". In one case, sending to such addresses resulted in a spam complaint from one of our recipients. This experience became a lesson for me: sending to role addresses is inappropriate. To avoid such situations, you need to carefully check your existing addresses for these “traps.”

Then I encountered spam traps. These addresses are created specifically to track bad senders. If you have similar contacts in your database, this may lead to your domain being blocked. We ran the database through a list of known spam traps, and ultimately excluded 6% of addresses that posed a potential threat.

One-time addresses and SMTP verification 📬

Personally, I was shocked to learn that our database contained disposable addresses. That is, there was no point in sending mailings to such addresses. Our validator found disposable domains and suggested deleting them.

And of course, checking using the SMTP protocol. Each message was sent to the specified address to check its activity. As a result, we increased the delivery rate of our mailings, and the level of trust of our clients increased.

Ultimately, this whole experience reminded me of the importance of working with data carefully. The quality of addresses can be a decisive factor for a successful business. Best practices I've learned include regular checks, using validators of varying difficulty levels, and closely monitoring changes to the database.

👩💻 Final walkthrough of validation methods:

Each of these steps was important to creating a successful database with which it was possible to work. Now, having such knowledge, running a business has become not only easy, but also an exciting process!
