What is a temporary email address and what is it for?

Temporary email addresses are a godsend for those who want quick information. You know those things you know you’re only going to access once in a lifetime? This is it!

You want to register your email address to take part in a prize draw, for example. Or a form that gives you access to some random material you’d like to know about (an ebook of something).

The temporary email address (also called disposable) is used to access services with which you don’t want to create a digital relationship.

When you make a purchase in an e-commerce store, that store will send you new products frequently, so that you will buy again.

This is because your email address is registered as a lead in the e-commerce system.

As well as preventing communications from sources you don’t want, the temporary email address protects your main account from receiving spam.

Remember that any unauthorized message is spam.

While temporary email addresses are good for some, they are a loss for others. Here’s who gets the worst of the disposable emails.

Who loses with the temporary email address: the other side of the coin

So far, the temporary email address is very practical for the consumer. But for professionals who work with email marketing, this service represents a big loss. Let’s see why.

Disposable emails become bounces. And mailing lists that contain up to 3% bounces are blocked by ISPs.

This rule is valid for any size base, regardless of whether it contains 100 or 1 million emails.

In short, it means that temporary emails will be blocked sooner or later.

And when an IP has emails blocked frequently, the worst thing happens: it is classified as a spammer, taking all email marketing investment down the drain.

But calm down. There are ways to prevent the damage caused by temporary emails.

How to protect mailing lists from temporary emails

The SafetyMails real-time email verification API protects landing pages, websites and applications from disposable emails, spamtraps and all kinds of invalid emails.

The registration form is thus shielded, generating only real leads. The verification API detects the temporary email address at the time of typing and suggests an automatic correction.

This way, the user can only access the web service if they enter a valid email address.

Bulk email verification, on the other hand, deletes bad emails from lists, keeping the base healthy for sending email marketing. In other words, all disposable and invalid addresses in general are eliminated.

In addition to the exclusion of invalid emails, there are other elements that guarantee good list preparation before sending. Watch our webinar and see what they are!

The characteristics of the temporary email address

Disposable email self-destructs between 2 minutes and 48 hours.

It therefore expires very quickly and the documents disappear automatically.

The user who opts for this service remains anonymous, both for the services they access and when they register with the temporary email generator.

Temporary email generation services do not store any information about the messages the user has received or sent via their disposable email.

How temporary email address platforms work

In addition to maintaining user privacy (you don’t need to register your main email address to generate a disposable address), the platforms direct all messages to the inbox.

Taking into account the short life of the service, the temporary email address does not have folders for main emails, social and promotions, as is the case with Gmail and other providers.

It’s important to note that since disposable email has no backup and self-destructs, it can’t be recovered.

Why not open a free email account instead of a temporary one?

The process of opening a free email account takes a lot longer. You need to create a username, a password and answer questions such as date of birth, phone number for password recovery, etc.

Creating a temporary email address requires none of this. Most platforms generate the email automatically on the login page, without you having to fill anything in.


The temporary email address represents convenience for the user, while at the same time it means losses for email marketers.

So if you work with bulk emails, make sure you sanitize your lists regularly!


Are temporary email and disposable email the same thing?

Yes, both names mean an email with a very short lifespan.

How does the temporary email address work?

Temporary email addresses are a service offered by various online platforms for people who want to create addresses that only last for hours or days.

These are emails created to access quick services (taking part in a promotion or downloading an ebook, for example), through which no digital relationships will be generated.

Why are temporary email addresses a detriment to email marketers?

Because they become bounces, and lists containing only 3% bounces are blocked by ISPs. When an IP receives recurring blocks, its reputation goes downhill and ISPs classify it as a spammer. This is bad news for anyone who uses bulk email as a communication channel.

How do you reverse the damage caused by temporary emails on mailing lists?

Email verification, which eliminates temporary emails and other types of invalid emails from lists. The real-time verification API protects registration forms from bad emails, and bulk verification excludes risky addresses.

Does the temporary email address pose a virus threat?

No, because this email is not stored on your computer or mobile device. In addition, the short lifespan of the service (most only last 1 hour) makes it difficult to receive phishing messages.

What are the advantages of using a temporary email?

Access promotion sites, discount coupons, take tests, connect to free Wi-Fi and many other services while remaining anonymous. This way, you protect your main account from spam, as well as tons of connection-generating emails.
