How to check if an email address exists

You’ve probably had to check if an address is real before sending out an email to someone.

The challenge, however, is doing this without actually sending an email and risking bounces or getting flagged as spam.

Thankfully, there are clever ways to verify email addresses without hitting the “send” button.

Use an email verifier

Bouncer - email verification


One of the easiest ways to verify email addresses is by using a tool like Bouncer.

Bouncer checks if an email address is valid without sending a message. It connects to the mail servers and uses the Simple Mail Transfer Protocol (SMTP) to see if the recipient’s server can receive emails.

Thanks to Bouncer, you know if the email server will accept the email for the recipient address you are checking. 

The tool also filters out disposable email addresses, so you only keep the real ones in your list.

You can try Bouncer for free. It’s straightforward: you upload your list, and it checks all the email addresses for you. The results will tell you which emails are valid, invalid, or risky.


  • Upload smaller batches of email addresses to the verifier tool to quickly identify patterns like common typos or frequently invalid domains. This helps catch disposable email addresses before they clutter your list.
  • Use Bouncer or a similar email verification tool to filter out emails. These tools connect to the mail server and check if the recipient’s inbox can receive emails.

Check the email syntax

Another quick way to weed out invalid email addresses is by checking their syntax. 

This means looking at the structure of the email address to be sure it follows the correct format. An email address should look like this: [email protected].

Here’s a simple checklist:

  • Make sure there are no spaces.
  • Look for an “@” symbol in the middle.
  • Check that there is a period (.) in the domain part after the “@”.

For example, “[email protected]” is correct, but “” is not, because it’s missing the “@” symbol.


  • Implement regular expressions (regex) in your email input forms to automatically validate email syntax. This reduces human error and catches improperly formatted addresses before they enter your system.
  • Give users tooltips or examples of correct email formats when they are entering their email addresses. This can reduce syntax errors and improve the quality of collected emails.

Search for the email address on Google

Sometimes, just Googling the email address can give you some useful information. 

Type the email address into Google and see what comes up. You can also search for the company name together with the “email address” phrase. If the address is associated with spam complaints, disposable email addresses, or other unwanted activities, you might find some red flags.


  • Enclose the email address in quotes (e.g., “[email protected]”) when searching to get more precise results. It can reveal any associations with spam complaints or disposable email addresses.
  • Add keywords like “spam,” “complaints,” or “review” along with the email address to uncover any negative associations.

Try to do a password recovery through an email service provider

You can also check if an email address exists by trying a password recovery through an email service provider like Gmail. 

Go to Gmail, type in the email address, and click “Forgot password.” If Gmail says the account doesn’t exist, then you know the email address is not valid. If it prompts you to proceed with recovery, the address is likely valid.


  • Besides Gmail, try the password recovery process on other popular email providers like Yahoo, Outlook, or any provider that matches the email’s domain.
  • Observe if the recovery process prompts security questions or other recovery options. If these options appear, it confirms that the email address is valid and actively used.

Check the age of the domain

Checking the age of the domain

New domains tend to be spammy, so checking the age of the domain can give you a clue about the email address. Tools like
Small SEO Tools can help you find out when a domain was created. If the domain is very new, it might be a disposable email address or used for spammy activities.


  • Use WHOIS lookup tools to get detailed information about the domain’s registration, including the owner’s contact details and registration history. New domains, often found through these checks, might indicate spammy activities.
  • Check the domain’s MX records using tools like MXToolbox to see if the domain has mail servers set up. If the domain name server doesn’t have MX records, then the email is likely invalid.


To sum up, there are many ways to check if an email address exists without sending an email. You can use email verification tools, check the email’s format, and look at the age of the domain. 

These methods keep your email list accurate and useful. Follow these steps to avoid spam complaints, reduce bounced emails, and make your messages reach the right people.

And remember – with Bouncer, the free email checker, you can check 100 emails at no cost.

Happy emailing!
