Disposable email addresses are a headache.
They let users bypass sign-ups, abuse free trials, and waste your resources. Businesses try to fight back with disposable email domain lists. It sounds like a good idea-block the domains, stop the abuse.
But there’s a problem. These lists are outdated the moment you create them. They can’t keep up with the speed at which temporary email services grow and adapt.
If you’re still using static lists, you’re probably putting in consistent effort for very little, or temporary reward.
Why disposable email domain lists don’t work anymore
Simply put, disposable email domain lists don’t work anymore because they’re always outdated.
New disposable email domains pop up every day. You might add 100 domains to your list today, but tomorrow, another 50 will appear. Keeping up is like trying to stop a flood with a bucket.
Worse, we’ve seen some temporary email services add new domains each day, with rotating IPs. This makes it impossible for manual lists to stay effective and up to date without significant effort.
And let’s be honest - these lists often rely on guesswork or community contributions. That means you’re probably blocking domains you don’t need to and missing ones you do.
In the end, a static list just can’t keep up with the pace of change. If you’re relying on one, you’re already very behind.
The problem with outdated lists
Outdated lists cause more problems than they solve. First off, they miss the mark. New disposable email domains appear constantly, but your list? It’s stuck in the past. It grows less effective every day, leaving opportunities for abuse.
And let’s not forget maintenance. Keeping these lists updated takes time and effort. Is that something you want to do every few weeks? Even if you stay on top of it, you’ll always be playing catch-up. There’s nothing worse than being on holidays, without a laptop, seeing abuse happening in real time to your service.
Then there’s the issue of false positives. Outdated lists often block legitimate domains by mistake. You might end up turning away real users, frustrating potential customers, or creating support headaches.
The simpler solution is to use a tool which doesn’t rely on block lists, but rather runs analysis on these domains and blocks them in real time. A few lines of code and you’re done.
How disposable email services evolve faster than your lists
Disposable email services are always one step ahead.
They don’t just stick to a single domain. They constantly add new ones, making it nearly impossible for a static list to keep up. Some even rotate domains automatically, so by the time you’ve caught on, they’ve already moved on. If a domain costs \(5, and they make \)1,000 a day from adverts, why wouldn’t they want to be the most effective disposable email service and keep users coming back?
Many of these services are clever, too. They deliberately choose domains that look legitimate or mimic real ones, or buy expired and dated domains. Your list might miss them entirely.
Have you also considered custom domains? By using your own domain, you can completely bypass these lists. You’ll always fly under the radar, and can then create as many trial accounts as you like. Not great for those of us who have underlying costs associated to free trials, like with AI credits.
I’m not sharing my customer emails with you!
You’re right! You shouldn’t, it’s a huge privacy issue.
That’s why we don’t ask for it.
We only need the domain part. Our systems can analyse, and detect a disposable email from the domain part exclusively. Sure we won’t be able to catch things such as plus emails, but that’s trivial for you to block. What’s hard is detecting if a domain is disposable or not, and that’s where we shine. Give our tool a try and see for yourself.
Why domain-based detection is the better option
Domain-based detection is simply smarter.
Instead of analysing entire email addresses, it only checks the domain. This approach keeps things efficient and avoids privacy issues. You don’t need to provide us personal data, so you stay on the right side of regulations like GDPR, and we know nothing about your users.
It’s also faster. With domain-based detection, you can validate emails in real-time without bogging down your systems. No massive lists to search through-just a quick check to see if the domain is disposable.
Most importantly, it’s future-proof. Services like Temp Mail Detector add new domains every day, so you’re always one step ahead. Unlike static lists, domain-based detection evolves in real time to keep up with the latest disposable email tricks.
Crawling the web vs. manually updating lists
It takes time to find new disposable email domains. You’re constantly hunting, guessing, and reacting. Even with the best efforts, it’s impossible to catch them all. Your services are still getting abused, and you’re being reactive.
Crawling the web, on the other hand, is like putting this on autopilot. Services like Temp Mail Detector scan the internet daily, looking for new disposable domains. No guesswork, no spreadsheets, no deduplication, no missed updates.
This automation doesn’t just save time - it’s more reliable. It can spot trends, track new domains as they appear, and adapt much faster than any manual process could.
The choice is obvious: do you want to spend hours on an uphill battle, or let a system that actually works handle it for you?
