There are several methods available that can help you identify usable email addresses. In the section below, we’re going to explain some of the common ways it can help.

Method 1: Check Out the Email Domain

The most common way to identify the disposable email address is by checking the domain. There are a large number of email services available which supports to create temporary email addresses and most of them use the specific domain which is really easy to spot. For example, some of the common disposable email providers are:

  • Mailinator (e.g., example@mailinator.com)
  • Guerrilla Mail (e.g., example@guerrillamail.com)
  • 10 Minute Mail (e.g., example@10minutemail.com)
  • Temp-Mail (e.g., example@temp-mail.org)
Note: If you notice an unfamiliar or generic domain in the email address, it’s a good idea to check if it’s a disposable email address.

Method 2: Look For the Random Characters

Most disposable email addresses are automatically generated, which means they appear with a string of random characters. If you’ve come across an email address that seems too random like abc123xyz@mailinator.com, there’s a good chance that this is a disposable or temporary email address.

Certain patterns in email addresses may indicate that they are usable email addresses. For example, if users are signing up with the different variations of the same basic email address like alex1234@mailer.com, alex5678@mailer.com, chances are they’re using a disposable email address.

Step 4: Recognize the Email Address Age

Some email services limit the duration of email addresses so that the email may not be active for that long. If you notice if the email address was created in a short period of time or doesn’t appear to have been used before, this could be a disposable email address.
