Protect Your List
Block Throwaway Emails and Protect Your Email List from Spam Signups
Each fake email on your email list is a lost lead. You spent money on getting that lead, and if it's a throw-away address, you're sure you'll never be able to contact that lead again. The email might work once, but it will be abandoned or deleted within a short amount of time.
Detect disposable emails at signup in order to:
- Prompt the user for real addresses
- Treat them differently in your marketing funnel
Definition
What Are Disposable Email Addresses?
Disposable email addresses (temporary or throwaway) are email addresses that are designed to be used only for a limited period. The sites Guerrilla Mail, 10 Minute Mail, and Temp Mail allow anyone to instantly create an email address that will last just long enough to capture a confirmation email. They are then discarded.
The primary uses are to get past registration pages, access valuable content, or avoid spam emails; a user sees these as a privacy mechanism, and a marketer sees it as a disaster of data quality.
Business Impact
Why Disposable Emails Hurt Your Business
Worthless Lead Data
Anyone signing up with a throwaway email will be a lead you can't follow up with. Nurture campaigns, sales follow-ups, or even basic promotional messages will never be seen. You've paid to gather a contact that can't generate revenue.
Increased List Expenses
Disposable email addresses are included in all costs for most email marketing services. Yet you're paying to add and perhaps send to addresses that will never buy. Removing Disposable email addresses will lower costs without reducing your available audience.
Distorted Analytics
Fake email addresses skew your signup figures, conversion reports, and overall list size metrics. If you're not careful, you could be losing a significant percentage of your leads to bogus email addresses.
Deliverability Difficulties
Disposable email providers sometimes become spam traps if their users leave addresses inactive. Sending mail to these addresses can harm your reputation, despite initial signups being legitimate.
Wasted Resources
Your customer reps may waste hours contacting disposable addresses, while support agents may waste minutes replying to queries from junk email addresses. Every time a fake address is interacted with, resources are wasted.
Provider Types
Hot Common Disposable Email Providers
There are many hundreds of disposable email providers out there. This list highlights just some of the more popular services.
Major Names
Guerrilla Mail, 10 Minute Mail, Mailinator, ThrowAwayMail, and YOPmail are widely used. These sites allow for rapid creation of non-registered accounts. Some keep addresses available for seconds, and others for days.
Unknown Names
In addition to the household names, hundreds of smaller disposable email providers exist. They often serve niche communities or are used by regional demographics. Detecting them all is essential.
Self-Terminating Names
Other services automatically delete accounts after specific time frames, or require manual removal. Either method can nullify addresses when a user has finished with them.
Detection Methods
How Fake Email Checker Tool Finds Disposable Addresses
We use a number of techniques to determine if an email is disposable or not.
Database of Used Domains
We have a constantly growing database of known disposable email domains. We compare the provided email's domain to our database, and if it is listed, we right away know the email is disposable.
Recognition of Disposable Email Patterns
Disposable email services are constantly changing and thus, hard to keep up with. We use pattern recognition on both the domain names and the names of the domain's mail servers to recognize the patterns of a disposable provider.
Domain Behavior
Some markers of a disposable email provider are the way the mail servers are configured, as well as the number of aliases linked to the domain.
Real-time Updates
Disposable email providers change all the time, so in order to recognize all new disposable services, we constantly update our database so you're always protected.
Prevention
How to Block Temporary Email Addresses on Your Website
01
Real-Time Form Validation
The best way to do this is actually email verification on signup. When a user signs up, they give us their email address, and we make an API call to our service to determine if the address is disposable. If it is, then we show an error prompt and ask for a different address.
02
Soft Blocking
Disposables should not be turned away altogether. Some companies continue to accept signups but identify these leads to treat them differently.
03
Post Signup Cleaning
So if you can't do real-time validation, at least periodically cleaning your lists will rid the trash addresses after the fact. It's not as good as blocking signup, but better than not doing it at all.
Frequently Asked Questions About MyEmailVerifier Fake Email Checker Tool
Can people always find a way around disposable email detection?
If someone genuinely cares, they will find a way to bypass basic detection. That's why we recommend disposable email services to prevent casual use. Even the most determined will find it inconvenient.
Are all temporary emails bad?
From a business perspective, the truth is that most users who sign up with disposable email addresses are not interested in long-term communication. For your application, consider whether that's a problem.
How frequently do you update the list of disposable/fake domains?
We update our disposable email database daily, which is crucial to catch the latest disposable email domains. Without updates, we risk allowing these domains to go undetected.
If I block disposable emails, will that impact my incoming signups?
There may be a small reduction in raw signup numbers, but the majority were clearly invalid leads anyway. Your actual conversion rate will stay the same, but the quality of data you receive will improve.
Does this include free email providers (Gmail, Yahoo, Outlook)?
Free email providers are not disposable email providers. Although some individuals use free email accounts for business purposes, these email addresses are deliverable and therefore not disposable.
How does the bulk fake email checker tool work?
While we only offer single email checking on this page, our bulk checking service is ideal for auditing existing email lists. Simply upload your list, and we will let you know which are disposable.
