Welcome to SpamBuster.

Our innovative email verification service ensures that only emails from your contacts or previous correspondents reach your inbox. For unfamiliar senders, we simply verify their authenticity. Say goodbye to spam and scams, and hello to a cleaner inbox.

Not like other spam blockers

Block-lists fail. Allow-lists win.

If you’re here, it’s because your anti-spam or anti-virus just doesn’t work. They try to block bad senders. That’s never going to work — senders just change their email address or use a VPN.

SpamBuster completely changes the model. Instead of blocking bad senders, we allow good senders. Instead of you tracking down whether a sender is human, we make the sender verify they’re real — one click, one time. After that, email flows just as before.

No email is ever deleted

You never miss a message, nothing is deleted. Unknown senders cannot land a message in your inbox without verifying they’re human and the message isn’t spam.

For individuals

Your inbox. Your rules.

Most spam-blocking services are built for big IT departments and move control of your inbox to the tech team. SpamBuster gives you full visibility and control over what lands in your inbox — and it works alongside the other blocking tools you already have.

1

SpamBuster checks

When an email arrives, SpamBuster checks to see if it’s on an allow list (your contacts, anyone you’ve emailed). If not, the message is moved to your SpamBuster folder.

2

Ask sender to verify

If you’ve never communicated with them, the sender gets a message asking them to verify they’re human. If they do, the message is moved to your inbox — with an information block about the sender attached.

3

Done

You have a clear inbox and full visibility into any new senders. Existing senders flow as before. New ones do a one-time, one-click verify.

SpamBuster vs others

Bad senders can’t get on your allow list.

Anti-spam tools blacklist email addresses, IPs and domains. A bad sender just changes IP or email address to bypass that. SpamBuster works the other way around — good senders earn one click of verification, once.

SpamBuster doesn’t block spam — it allows known senders.

FAQ

Questions, answered.

Does it work with my other spam and filtering software?
Yes — SpamBuster only looks at the messages that have made it past all those preemptive layers.
Does SpamBuster delete my messages?
No, SpamBuster simply moves unknown messages to the SpamBuster folder, and then will move them to the inbox if either you or the sender verify it’s not spam.
Can I manage which senders and domains are approved senders?
Yes, absolutely. If you allow, SpamBuster can create the initial approved lists by looking at your Sent Items and addresses in your contacts. You always have full control of who is allowed and which lists are active. No person sees your contacts, and your contacts are never emailed — it just allows previous contacts to bypass verification.
Do I have to let SpamBuster see my previous senders?
No, but it’s a way to avoid having all your previous correspondents verify. It’s up to you — verification is only needed one time and is only one click. Starting with a blank approval list works well too.
Will you use my contacts?
Absolutely not. We made this service to help people, not make anyone angry. We won’t use your contacts and we won’t sell your data. We’re saving your inbox from spam and scams.
Does SpamBuster need my username and password?
Not always. For example, with Gmail, you can log in on the Gmail side and grant SpamBuster permissions without ever sharing your credentials. For email services that don’t offer API access, you can add your account information.
Do I need to install an app?
No, just configure SpamBuster here on the website and you’re good to go.
Does SpamBuster work with all my devices?
Yes! Any device that checks your inbox will get the benefit of SpamBuster. No app, no per-device setup — a one-time setup on the website and you’re done.
Does SpamBuster work with distribution lists?
Yes. SpamBuster works on messages that have landed in your inbox. If a distribution-list message ends up in your inbox, SpamBuster will check it.
What if I want someone to email me without needing to verify?
Two ways. The cool way is to give them your secret code: if my email is bob@gmail.com and my secret code is ABCD, the sender uses bob+ABCD@gmail.com. You can change your code in settings anytime. The other option is to add them to your verified-senders list.
Can I see what actions SpamBuster took on my emails?
Yes. We believe in full transparency — view the actions log to see when messages arrive, if the sender clicked verify, if a sender matched a verified list, and what SpamBuster did.
Will SpamBuster ever send a message as me?
No. Verification emails are sent from SpamBuster, not your address. And we will never send a message as you.
What protocol does SpamBuster use?
SpamBuster uses direct APIs when available. If not, it uses the proven IMAP protocol that has been around for decades.
Does it work with my Outlook rules?
Yes. Outlook rules execute when Outlook is running. SpamBuster runs even in the background and may end up executing before your Outlook rules.
I have corporate email — can it work for me?
Yes, if allowed by your IT department. Enterprise-specific features are coming soon. Email us at hello@spambuster.co — and don’t be surprised when you get a link to verify that you’re human.
