Is This Email Valid? 5 Best Ways to Find Out

Feb 14, 2024

In email marketing, sending a message can sometimes feel like dispatching a message in a bottle into the digital ocean.

You hope it finds a recipient, but too often, it seems to vanish without a trace.

The question then becomes: How can you be sure that the email address you’re about to use is not just another drop in this unresponsive sea?

We’re here to answer it.

Why sending emails to invalid addresses is bad

Sending emails to invalid addresses can lead to major problems that can negatively impact your email marketing efforts. 

Lower email deliverability

When you send emails to addresses that don’t exist, your mail server keeps bouncing back these emails.

This signals other mail servers that your sending practices might not be reliable.

As a result, even valid emails might not reach their intended recipients.

Tarnished sender reputation

Your sender reputation is very important in the email world.

Continuously sending messages to non-existent email addresses can harm this reputation.

Once tarnished, it becomes challenging to regain the trust of email servers.

Poor email marketing results

The success of email marketing relies heavily on reaching actual people.

If your emails are mostly going to invalid addresses, you’re missing out on potential engagement and conversions.

This inefficiency can lead to poor overall results from your email marketing campaigns.

Risk of getting blacklisted

If you consistently send emails to invalid addresses, it’s not just individual mail servers you have to worry about.

Your domain could end up on a blacklist, which is shared across many email servers. Once you’re blacklisted, it becomes a daunting task to get off these lists and restore your email deliverability.

How to check if an email is valid

To avoid these issues, it’s essential to verify email addresses before sending out mass emails.

Here’s how you can do it quickly in 5 different ways:

Send an email to the address

A simple yet sometimes effective way to check if an email is valid is to send a test email.

Write a brief, neutral message and send it to the address in question.

If the email bounces back, it’s a clear sign that the email address may not be valid.

However, remember that some email servers are configured to not send bounce messages, so a lack of response doesn’t always mean the address is invalid.

This method can be time-consuming if you have a large list, but it’s a straightforward approach to validate email addresses.

Try a password recovery process

This method involves using the password recovery feature on an email service page.

For example, you can enter the address into Gmail to get to the next page, asking you for a password. If the address does not exist, Gmail won’t ask you for a password.

This doesn’t necessarily confirm the email is active, but it can indicate whether the email address is registered on that platform.

Be cautious with this method to respect privacy and avoid any actions that might be interpreted as unauthorized attempts to access someone’s account.

Do an IP address lookup

Conducting an IP address lookup can sometimes help in validating an email address.

This involves checking the IP address of the SMTP server associated with the email address.

By analyzing the server’s IP, you can get clues about the legitimacy of the email address.

For instance, if the IP address is listed on blacklists, it might indicate that the email address is used for spamming.

However, this method requires technical knowledge and might not always provide conclusive results, especially with temporary email addresses that often use different IPs.

Search the address on Google

Lastly, a simple Google search can sometimes yield information about the validity of an email address.

Just type the email address into the search bar and see what comes up.

If the address is associated with public profiles, websites, or has been mentioned in forums or articles, it’s likely a valid address.

This method won’t always work, especially for newer or more private email addresses, but it’s a quick and easy step that can be part of your overall email verification process.

Remember, though, that the absence of search results doesn’t necessarily mean the email is invalid.
