Buying or Selling on Craigslist, Facebook Marketplace? Use a Temp Email

Introduction

Classified marketplaces like Craigslist, Facebook Marketplace, and Kijiji are fantastic for finding deals and selling used items. They connect you with local buyers and sellers without the overhead of traditional e-commerce platforms.

But they also come with a privacy risk that most users don't think about: your email address is exposed to strangers.

When you list an item or respond to an ad, your email address can end up in the hands of people you don't know — and some of them may not have good intentions. Here's why you should always use a temporary email for classified transactions.

How Classified Platforms Handle Your Email

Different platforms handle contact information differently:

Craigslist uses an anonymized relay email system by default — replies go through a Craigslist address that forwards to your real inbox. However, many users disable this feature or accidentally expose their real email in messages.

Facebook Marketplace routes communication through Facebook Messenger, which protects your email but exposes your Facebook profile (name, photo, mutual friends, location).

Kijiji / Gumtree / other local classifieds often display your email directly in the listing or require you to include it in your reply.

Even when the platform provides anonymization, motivated users can often find ways to extract your real email — especially in direct messages where you might accidentally include it.

The Risks of Exposing Your Email in Classifieds

Harassment and Stalking

When you list an item, strangers know you have something they want. If negotiations go poorly, some people resort to harassment. Having your real email makes it easy for them to escalate.

Spam and Scam Targeting

Classifieds are a favorite hunting ground for scammers. Your email goes on their lists, and you start receiving:

Fake payment confirmation emails
Phishing messages impersonating the platform
"Buyer" inquiries for items you never listed
Offers for "shipping services" and other scams

Personal Information Correlation

With your email, a determined person can find your social media profiles, your employer, your home address (via data brokers), and even your family members. A simple furniture sale can lead to a significant privacy breach.

Persistent Contact

Even after the transaction is complete, the other party has your email. They can contact you weeks or months later, for any reason, and you can't easily block them if you don't know which of your classified conversations it's from.

How Disposable Email Protects You

Using a disposable email for classified transactions gives you multiple layers of protection:

Inbox isolation. All transaction-related emails go to a temporary inbox. When the deal is done, the inbox expires. No lingering contact.

No real identity. The buyer or seller never learns your real email, making it much harder to find your personal information online.

Transactional compartmentalization. If you're selling multiple items, use a separate disposable address for each listing. A communication issue with one buyer doesn't affect your other transactions.

Easy abandonment. If a buyer becomes harassing, you can simply stop checking the disposable inbox. No need to block, report, or change your real email.

Best Practices for Classified Transactions

For Sellers

Remove your email from listings. Most platforms have a "reply via platform" option. Use it.
If you must include contact info, use a disposable address from Expira — not your real email.
Create a new address for each listing. If you're selling a couch and a laptop, use two different addresses.
Communicate through the platform as long as possible. Only move to email when necessary (e.g., sharing additional photos).
Let the inbox expire after the item is sold and the transaction is complete.

For Buyers

Respond to listings using a disposable address. Don't use your primary email for initial contact.
If the seller seems legitimate, and you need ongoing communication, you can always share your real email later.
Watch for phishing replies. Scammers pose as sellers and send fake payment links. Using a disposable address contains the damage if you click something you shouldn't.

What About Phone Numbers?

Many classified transactions eventually involve sharing phone numbers for coordination. The same principle applies: use a temporary or virtual number when possible, or share your number late in the process only when you're confident the person is legitimate.

The Expira Connection

Expira is the perfect tool for classified transactions. Since these interactions are inherently temporary — you're connecting with a stranger to complete a one-time transaction — a temporary email address is the natural fit.

Keep Expira open while browsing listings. Generate a fresh address for each interaction. When the deal is done, move on with no cleanup required.

Conclusion & CTA

Classified marketplaces are useful, but they expose you to people who don't need permanent access to your inbox. A disposable email address gives you the benefits of these platforms without the privacy risks.

Stay safe while you buy and sell. Generate a transaction-specific address at Expira before your next Craigslist or Marketplace interaction.
