Discovering infidelity is difficult, but deciding how to tell someone their spouse is cheating anonymously can be even more complex. You may feel a moral obligation to share the truth while also wanting to protect your identity.
This guide covers safe, practical ways to deliver sensitive information discreetly, helping you navigate the fine line between honesty and privacy. From digital methods to old-fashioned notes, each option ensures you can warn someone without risking exposure.
It’s important to handle these situations with care, respect, and clarity to avoid unnecessary harm or misunderstandings while keeping your identity fully protected.
1. Send An Anonymous Email
One of the easiest ways to inform someone discreetly is by sending an anonymous email. In Singapore, using a secure, no-log service such as ProtonMail or Guerilla Mail allows you to create a burner email account that leaves no trace of your real identity.
Make sure to access these services via public WiFi or a VPN for added privacy. Keep your message brief, respectful, and factual—avoid emotional language or accusations. It’s also wise to provide clear evidence if available, so the recipient takes the information seriously.
Always double-check that you haven’t included any personal clues, such as your writing style or details only you would know.
2. Use A Tip-Off App Or Service
Several apps and platforms offer anonymous reporting features that help you stay completely hidden. Apps like Whisper and Secret (if available in Singapore) allow users to share confidential tips without revealing personal details.
Alternatively, some neighbourhood or community apps provide anonymous messaging functions, though caution is needed to ensure they don’t track metadata. For maximum safety, use these services over a public WiFi network or with a VPN.
These platforms are ideal for sending brief tips or evidence discreetly, but make sure your message is clear and precise, as vague warnings may be ignored or misunderstood.
3. Write And Post An Anonymous Letter
A handwritten or printed letter remains one of the most traditional ways to send an anonymous tip. When writing your letter, keep it neutral and fact-based, avoiding any emotional wording or personal opinions that might give clues about your identity.
In Singapore, posting can be done through any SingPost mailbox, and to enhance anonymity, post it far from your usual locations. Do not include your handwriting if you believe it could be recognised; instead, print the letter from a public printer if possible.
Seal the letter securely and avoid using any stationery or ink that could be traced back to you. The goal is to deliver a respectful, clear message that informs the recipient without compromising your own privacy.
4. Use An Anonymous Texting Service
In Singapore, anonymous texting services allow you to send a confidential message without exposing your personal phone number. Apps like Hushed or TextNow provide disposable numbers that can be used temporarily to send a one-off SMS.
Alternatively, certain web-based services offer single-use text messaging options, but always check their privacy policies to ensure no trace is left. For added security, connect via a VPN and public WiFi when setting up the service.
Keep your message brief and direct, stating the facts without unnecessary detail, and double-check that no identifying information, such as slang or location hints, slips through.
5. Leave A Note In Their Mailbox Or Car
Leaving a note is a simple, old-school way to pass on information anonymously. In Singapore, you can discreetly place a folded note in the person’s HDB mailbox or, if accessible, on their car windscreen or tucked under the wiper.
Ensure your note is printed to avoid handwriting recognition, and prepare it in advance to limit your exposure time. Choose a quiet time of day when fewer people are around, and avoid using distinctive paper or envelopes.
The note should be clear and factual, with no personal opinions or extra clues. Make sure it’s sealed or secured so it won’t blow away or be seen by others before the intended recipient.
6. Create A Fake Social Media Account
Setting up a fake social media account can be an effective way to send a private, anonymous message. In Singapore, platforms like Facebook, Instagram, or Telegram require basic sign-up details, but you can create a new identity using a burner email and avoid linking any personal information.
Use generic photos and names, and never connect the fake account to your actual phone number. Before messaging, review the privacy settings to ensure the account can’t be traced.
Keep your message concise and to the point—explain the situation politely and provide any evidence if available, while steering clear of emotional or accusatory language that could raise suspicion.
7. Ask A Mutual Friend To Relay The Message Anonymously
If you share mutual contacts with the person you want to inform, a discreet way to handle the situation is by asking a trusted friend to relay the message on your behalf. In Singapore’s close-knit social circles, choose someone who is reliable, discreet, and unlikely to expose your involvement.
Be clear about the facts and stress the importance of keeping your identity confidential. This approach can feel more personal and credible since the tip comes from a familiar face, but always consider the risk that the friend may unintentionally reveal more than you intend.
8. Drop A Tip Via Their Workplace Suggestion Box
Many workplaces in Singapore, especially larger corporations, have anonymous suggestion boxes or feedback systems. These can be a creative way to pass on sensitive information without revealing your identity.
Prepare a concise, printed message that avoids emotional or accusatory language and stick strictly to factual details.
Post the message in the box at a quiet time to reduce chances of being seen. If the workplace also has digital feedback forms that allow anonymous submissions, these can be even more secure and faster for delivering your message.
9. Use A Public Phone Booth
While rare today, public phone booths still exist in some parts of Singapore, especially in older estates or certain public areas. Using a payphone can be one of the most anonymous ways to make a brief call without leaving a digital trace.
Before calling, rehearse what you want to say to keep the conversation clear and concise. Avoid using personal phrases or speech patterns that might give you away.
A simple message such as “I have information you should know about your spouse’s behaviour” followed by key facts is usually sufficient. Once the call is complete, leave immediately and avoid returning to the same booth to maintain your anonymity.
10. Post On An Anonymous Online Forum
Singapore-based online forums and discussion boards—such as Reddit or local community sites—offer options for anonymous posting. When using these platforms, avoid logging in from personal accounts and consider using a VPN for extra privacy.
Craft your post in a way that provides enough context without naming names publicly; instead, you might describe the situation generally or invite the person involved to reach out privately for more details.
Ensure your language is factual and neutral to avoid defamation concerns, and monitor any responses cautiously to avoid revealing more than intended.
11. Send Anonymous Proof Via Courier
If you have physical evidence—such as printed photos, messages, or documents—you can send them anonymously using a courier service in Singapore. Services like Ninja Van or Qxpress allow you to deliver parcels without needing to include your name on the sender label.
To maintain privacy, prepare the package yourself and avoid returning to the same courier branch repeatedly. Use plain packaging with no distinctive markings, and consider adding a brief, typed note for context.
Always double-check that your evidence does not contain personal clues like metadata or handwriting that could reveal your identity.
12. Use A Library Or Public Wifi To Send Messages
Sending digital messages from public WiFi hotspots adds a crucial layer of anonymity. In Singapore, public libraries, cafés, and community centres offer free WiFi, making them ideal locations to use temporary email accounts or messaging apps.
Connect through these networks instead of your home or mobile data to mask your IP address further. For added safety, use a VPN while online and clear browser history before logging off.
Keep your message brief and factual, and avoid signing into any personal accounts while connected to maintain total separation from your identity.
13. Set Up A Temporary VoIP Number
A temporary VoIP number is a great option if you need to make an anonymous call or send a text discreetly. In Singapore, apps like Hushed, TextNow, or Google Voice (when accessed via VPN) let you generate disposable numbers for short-term use.
Set up the account using a burner email and avoid linking it to your real phone number. Always use public WiFi or a VPN when registering and sending messages to keep your digital footprint secure. Once your message is delivered, delete the account and app to ensure no records remain on your device.
14. Use A Disposable Phone (Burner Phone)
A burner phone offers one of the most foolproof ways to stay anonymous. In Singapore, prepaid SIM cards and cheap mobile phones are available at convenience stores or small electronics shops. Buy the phone and SIM with cash to avoid any traceable link to your identity.
After using it to make a one-time call or send a text, power it down and dispose of both the SIM and device safely—do not recycle them at familiar locations. This method is ideal if you want full control over the message delivery without relying on third-party apps.
15. Create A Fake News Tip
In high-profile or sensitive cases—such as if the unfaithful spouse holds a public role—submitting an anonymous news tip might be a discreet way to expose infidelity indirectly. Singapore’s media outlets, like The Straits Times or online platforms, often have tip-off channels that allow anonymous submissions.
Prepare your tip with care, ensuring it focuses on factual details rather than personal opinions. Only use this route if the affair has public relevance, such as involving community trust or public funds; otherwise, it may not be the most ethical option.
Use a burner email or public WiFi when submitting to keep your identity fully protected.

Frequently Asked Questions About Ways To Tell Someone Their Spouse Is Cheating Anonymously
Should I Confront The Cheating Spouse Before Telling Their Partner Anonymously?
Confronting the cheating spouse can be risky, especially if you want to remain anonymous. It may lead to defensiveness, denial, or even retaliation. If your goal is simply to inform the affected partner discreetly, it’s usually safer to avoid direct confrontation.
Does Anonymously Reporting Cheating Ever Backfire?
Yes, anonymous reports can sometimes backfire if the message is perceived as malicious or lacks credible evidence. This may cause unnecessary stress or distrust, so it’s essential to be clear, factual, and respectful to minimise misunderstandings.
Can My Ip Address Be Traced If I Send An Anonymous Email About Cheating?
If you use a standard email service, your IP address can potentially be traced. To stay fully anonymous, it’s best to use a secure, no-log service like ProtonMail or send messages over public WiFi.
Are There Risks To My Personal Safety When I Report Cheating?
While anonymity reduces personal risk, there’s always a small chance of being identified, especially if you share too much detail. Taking strict precautions and avoiding personal identifiers will help keep you safe.
Should I Include Screenshots Or Photos When Reporting Infidelity Anonymously?
Including clear, verifiable proof like screenshots or photos strengthens the credibility of your message. However, ensure the evidence is genuine and avoid sharing anything that could accidentally reveal your own identity.
