According to data collected in 2019, the number of email users globally equaled 3.9 billion. And by 2024, the number is expected to touch 4.5 billion. It is an excellent chance for the email marketing domain. However, it's essential to note that the email users can include all kinds of users, which also counts the disposable email account users. And what most business owners need to realize is that they should keep a watch for these accounts.

When it comes to a disposable email, you need to know three things about it to have better information. That way you can use it better.

• 1. Understanding disposable email addresses and domains

Simply put, a disposable email domain indicates the domain's name that gets appended to any temporary email id. It also gets referred as "throwaway" or "burner" email addresses. The disposable email addresses are meant for short-term use and provide the users a sense of anonymity. You can use it anytime you wish to and after that you can retain your privacy.

• 2. Why are most people opting in for disposable email ids?

It is wrong to assume that disposable email users are malicious. These users are mostly interested in maintaining their online privacy and want to avoid spam emails. Hence, you should not take a judgement call on this based on your bias. However, today, a few organizations primarily depend on a freemium model or structure and don't enable personal or disposable email addresses for subscription or registration to their websites. It’s because when a marketing message gets sent to a throwaway email account it has a hard bounce and can adversely affect the domain reputation. And when there is an increased bounce rate, it can blacklist an organization in the spam blocklist.

And at times things can get a bit challenging if the threat actors disseminate malicious and phishing emails with the help of disposable email ids. That way tracking the attack will get challenging. However, if you wish to avoid phishing or any such online attacks that result from spam emails, you can opt-in for disposable emails. It is the number one reason why most people use it when they are planning to sign-up to any blog or website.

• 3. The types of disposable email addresses

Today there are three kinds of the disposable email address. They are:

• Throwaway email address – You can use it only one time and use it to sign-up for any newsletter or other subscription and then forget about it.
• Alias email address – It uses free email services that are legitimate like Outlook and Gmail. It is an extra email address from the original provider which they use. And opposed to the primary email address, it gets used mostly for any registration purpose.
• Forwarding email addresses – It is also called a secondary email address that most people use to sign up in any website. And in comparison, to the alias email address, even though it's from another service provider, they get set up for forwarding messages to the primary email address.

Once you learn about these essential factors about the disposable email address, you can decide on its use based on your requirement.
