How to verify an email address

Verifying an email address is essential for successful communication and marketing. It not only ensures that your messages reach valid accounts of real users, but also helps maintain a clean email list, as around 22.5% of addresses become invalid each year. Using email verification tools like RealMail can quickly identify issues such as invalid mailboxes or syntax errors. Other methods include pinging the server to check validity or simply sending a test email, although this last option could impact your sender reputation if overused. Regularly cleaning and checking emails through various methods ensures better deliverability and improves overall marketing effectiveness.

1. Why Email Verification Matters

Email verification is crucial for ensuring that marketing campaigns are effective and your are communicating with real customers. When you invest to capture new customers each email address you lost is money lost. When emails are sent to invalid addresses, they bounce back, which can harm the sender's reputation. Research shows that approximately 22.5% of email addresses become invalid each year, making it essential to maintain an updated email list. This not only helps in enhancing the chances of emails reaching legitimate addresses but also improves deliverability rates.

High bounce rates can lead to a sender being blacklisted, which significantly impacts future email campaigns. By verifying email addresses, businesses can maintain a positive email reputation, directly influencing their ability to reach the intended inboxes. Additionally, a healthy email list lowers costs associated with ineffective campaigns, as sending emails to invalid addresses can waste resources and time.

2. Ways to Check Email Validity

Checking the validity of an email address can be done through several methods. One of the most efficient ways is to use an email verification tool. These tools can quickly verify an address via API in real-time, or multiple addresses at once, checking for common issues like invalid mailboxes, domain errors, and even potential spam traps. For example, services like RealMail provide comprehensive checks to ensure your email list is clean and effective.

Another method is to ping the server. This involves querying the SMTP server associated with the email address to see if it exists. While effective, this approach requires some technical knowledge and can risk your IP being blacklisted if done improperly.

A simpler but less reliable method is to search for the email address on Google. This can sometimes reveal if the email owner has a digital footprint, but it doesn’t guarantee that the email is valid.

Lastly, sending a test email is a straightforward way to check validity. If the email bounces back, you know it’s invalid. However, be cautious with this method, as frequently sending test emails can hurt your sender reputation. It’s best to use a separate account for testing to protect your main email address.

3. Common Steps in The Email Verification Process

To verify an email address effectively, follow these detailed steps:

  1. Syntax Check: Start by examining the format of the email address to ensure it follows the standard structure (e.g., username@domain.com). Look for common issues like missing '@' symbols or disallowed characters.

  2. Domain Check: Next, verify that the domain exists and is active. You can do this by entering the domain part of the email address into a web browser to see if it leads to an operational website.

  3. MX Record Check: Use tools like MXToolbox to confirm that the mail server for the domain is operational. This step ensures the domain can actually receive emails.

  4. Catch-All Check: Determine if the domain is a catch-all, meaning it accepts all emails sent to it, even if the specific address doesn’t exist. This can be done through specialized verification tools.

  5. SMTP Authentication (Email Address Ping): Finally, ping the SMTP server to check if the specific email address can receive messages. This requires some technical knowledge and may involve using command-line tools or specialized software.

By following these steps, you can systematically verify the validity of an email address and enhance your email list's quality.

But this does not include validating other key business elements such as the email address not being disposable, or temporary, not being a personal or free address instead of a business one, being a group or role address, etc.

4. Effective Email Verification Techniques

Effective email verification techniques are essential for maintaining a healthy email list and ensuring successful communication. One of the most efficient methods is to use an email verification tool. These tools can perform bulk verifications quickly, checking for invalid mailboxes, syntax issues, and even spam traps. Popular options include specialized email address verification api and services, which provide comprehensive solutions for email validation.

Another method is to ping the server, which involves querying the SMTP server to determine if an email address is valid. While this can yield accurate results, it requires technical knowledge and carries the risk of blacklisting your IP if not done carefully.

You can also perform a simple Google search on the email address. This can sometimes reveal information about the email owner, but it's not always reliable and may not confirm the email's existence.

Sending a test email is another option, but it should be used cautiously. This method verifies if the email can receive messages, but frequently sending tests can increase bounce rates and negatively impact your sender reputation. It’s wise to use a dummy account for this purpose to avoid affecting your main account’s reputation.

Combining these methods can yield the best results. Regularly cleaning your email list and integrating verification processes into your marketing workflow are also vital for maintaining high deliverability rates.

  • Use double opt-in methods to confirm email validity.

  • Leverage email verification tools and software.

  • Implement syntax checking to catch formatting errors.

  • Validate domain existence with DNS lookup.

  • Check for disposable email addresses.

  • Monitor engagement metrics to identify inactive users.

  • Regularly update and clean your email list to remove invalid addresses.

5. Common Challenges in Email Verification

Email verification can present several challenges that can affect its effectiveness. One common issue is the existence of temporary email addresses. Many users create disposable emails for short-term use, which can lead to invalid entries over time. This makes it difficult to maintain an accurate list. Another challenge is the presence of spam traps, which are email addresses set up to catch spammers. If a legitimate business inadvertently sends emails to these addresses, it can harm their sender reputation.

Additionally, organizations may face technical hurdles, such as the difficulty in pinging the SMTP server due to restrictions or firewalls. This can prevent accurate verification of email addresses. Furthermore, relying solely on manual verification methods, like sending test emails, can lead to bounce rate issues and risk damaging the sender's reputation. Lastly, users may not always provide their correct email addresses, either due to typos or intention. This can skew the results of verification efforts and make it harder to build a reliable email list.

6. Recommendations for validate email addresses

Sometimes the founders or marketing managers of startups or SaaS are faced for the first time with the challenge of solving the problem of validating email addresses, and initially the task is given to the developers, and it seems very simple to them, because initially they do not see the depth and complexity of the whole problem, nor all its future aspects.

So they start by trying to apply an in-house solution to the simplest and most obvious aspects. Like fixing typos with libraries, checking if the domain has DNS configured. Then they try to find free email addresses, etc. But eventually they realize that no matter how much development they do, there are always more aspects to consider. Or the solution is too buggy to be perfect. And it becomes clear that they do not have, and will not be able to have, an up-to-date database of disposable addresses. That they cannot detect email traps, and many other aspects and details that emerge as they dig deeper into the problem.

Under these circumstances, teams finally realize that it is more profitable, faster and more effective to rely on existing tools specialized in this difficult task, which have been solving the problem for years.

7. Tips for Maintaining Email List Health

To keep your email list healthy, regularly clean and update it. This involves removing inactive users and invalid addresses. Aim to verify your list at least quarterly; this helps mitigate the 22.5% of email addresses that become invalid each year. Additionally, segment your list based on engagement levels. By identifying active, inactive, and new subscribers, you can tailor your campaigns, ensuring that your messages resonate with the right audience.

Another key practice is to implement double opt-in for new subscribers. This confirms their intent to receive emails from you and reduces the likelihood of fake or temporary addresses being added to your list. You should also monitor your email metrics closely. High bounce rates or low engagement can signal problems with your list's quality.

Lastly, maintain a consistent sending schedule. Regular communication keeps your audience engaged and helps in identifying those who might want to unsubscribe, allowing you to manage your list more effectively.
