Why Online Businesses Are Losing Money Due to Disposable Accounts

In today’s digital world, many online companies—whether they’re SaaS, or e-commerce stores—are offering free trials or free tiers to attract new users. However, this approach has also opened the door to a growing problem: the use of disposable accounts and the creation of multiple accounts by fraudulent users. The result? Significant revenue losses that could be avoided.

What is a Disposable Email Account?

A disposable email account is a temporary, self-destructing email address designed for short-term use or a specific purpose. Unlike regular email addresses, which are intended for ongoing use, fake email provides users with a quick and anonymous way to receive emails without the long-term commitment of maintaining an inbox.

In general, there are three different types of disposable email accounts.

  • Aliases are typically variations of a genuine mail address hosted by a popular inbox provider like Gmail.
  • Forwarding accounts hosted by a different inbox provider to the user’s primary email account forwards messages to that account.
  • Non-forwarding accounts send only one email message, which bounces after the first send, indicating that they have no value in their business database.
This is also true for phone numbers and other data.

The Problem with Disposable Accounts

Imagine you have an online store offering a free month of service. It all sounds great, but what happens when users start signing up with temporary email addresses and disposable phone numbers? These users have no intention of becoming real customers; they just want to take advantage of the offer.


This distorts your acquisition metrics and can lead to direct losses ranging from 1% to 5% of your annual revenue. In a competitive market, every percentage point counts.


Additionally, referral programs are another vulnerable area. Malicious users can create multiple accounts to refer themselves, costing your business a significant percentage of its profits. In fact, fraud is estimated to represent up to 6.5% of global revenue, translating to billions in annual losses.

Disposable emails are bad for email marketing

Over the years, email marketing has been a powerful tool for businesses to engage with their audience, nurture customer relationships, and drive conversions. Creating a clean mailing list is vital to achieve success for your email campaigns. However, the increasing use of fake email can significantly undermine the effectiveness of these campaigns.


Disposable email accounts, often used to avoid spam or protect privacy, can distort engagement metrics, damage the sender's reputation, and waste valuable resources. This comprehensive guide sheds light on the negative impact of disposable email accounts on email marketing and provides actionable strategies to mitigate these issues.
