Fake buyer leads from Zillow: how realtors filter spam on Mac in 2026

If you pay for leads on Zillow, you already know the pattern. A new lead arrives with a name, a phone number and a note that says the buyer is interested in homes. You call. Nobody answers. The email bounces, or the person has been browsing for a year and never meant to move. That lead still had a price. This page covers what fake and useless leads cost you, why they keep coming, and what you can do this week without buying another tool.

I could not find a published study that counts how many portal leads are fake, or how many hours agents lose to them. Treat any industry percentage you see without a source with suspicion, including the ones in marketing emails. Your own log will tell you more than an average. The routine below builds that log in about a week.

What fake buyer leads from Zillow cost you

The most direct cost is the fee. Zillow's Premier Agent page gives an average cost per connection of $223 in major metro areas and $139 in non-major metros. The page says the price varies by market, home values and expected connections, so your own number may be different. A connection that goes nowhere costs the same as one that turns into a sale.

Think about a whole month. Say most of the leads you bought were dead ends. Each dead end still had a price tag, so the one real buyer has to pay for the junk around them. That is the math worth writing down, and it is why a cheap-looking lead can get expensive fast.

Time is the second cost, and it is harder to see. Each junk lead takes a look at the record, a call attempt, maybe a text or two and a note in your CRM. Those minutes do not show up on the portal invoice. I could not find a verified figure for them, so the sheet later on this page is the way to measure yours.

Speed is the third cost. The 2011 Harvard Business Review article 'The Short Life of Online Sales Leads' opens by saying most companies are not responding nearly fast enough to online sales leads. A noisy inbox makes that problem worse. The real buyer who wrote at breakfast sits under a pile of junk when you finally look.

The U.S. Bureau of Labor Statistics put the median annual wage for real estate sales agents at $52,830 in May 2025. That figure describes employed agents, not what a self-employed agent keeps after fees. Use it for scale only. At that scale, a run of dead leads is a real hit to a year's pay.

Why fake and useless leads keep getting through

Start with the pricing. Zillow describes its cost as a cost per connection, and the price moves with the market and the home values. The price is set per contact, not per sale. Nothing in that price checks whether the person is ready to buy, so the quality check falls to you.

Many leads come from people who are browsing, not buying. They fill in a form to see a listing, ask a price or save a search. That is not fraud. It is low intent. It looks just like a serious buyer until you talk to them, which is why a screen has to happen before you call.

Some leads carry bad contact details. A mistyped phone number or a dead email address makes the lead impossible to reach. Zillow's public page does not say how the platform handles invalid contact details, so ask your account contact in writing before you assume a credit.

Spam filters miss these. Google says Gmail blocks more than 99.9% of spam, phishing and malware from reaching the inbox, and its filters learn from user feedback. A lead from a legitimate sender is not spam to Gmail. It lands in your inbox with the same weight as your client's mail. That gap is the problem this page is about.

Speed plays a part too. Without a routine, you read every lead the moment it arrives, and the junk breaks your focus. Then the real buyers wait. The fix is a routine that screens in batches, which the Day 4 step in the plan covers.

Sort portal leads in Gmail before they fill your inbox

A Gmail filter cannot tell a fake buyer from a real one. It can sort the mail, and that is the win. Put every portal email under one label, then read that label on your schedule instead of on every ping. You can build the filter from a message you already have open.

Open one lead email from the portal first. The filter copies its sender and any words you add. Here is the routine on a Mac in Chrome.

1. In Chrome, open the lead email in Gmail, then click More in the message toolbar.
2. Choose Filter messages like these.
3. Check the criteria. Keep the sender and remove anything that matches normal client mail.
4. Click Create filter, then turn on Apply the label and pick a label named Portal leads.
5. Open Settings > See all settings > Filters and Blocked Addresses to confirm the filter is there.

Gmail filters can also star or forward mail. Starring a hot lead is handy. Forwarding client details to a personal account is a bad idea, so follow your brokerage's rules before you forward anything.

Set up an Apple Mail rule if you read leads in Mail

If your portal email lands in Apple Mail, a rule does the same job. Apple's Mail guide for version 15.0 on macOS Sequoia says rules run in list order, and you can apply a rule to existing messages. With iCloud Drive on, the rule syncs to your other Macs.

1. Open Mail, then choose Mail > Settings > Rules.
2. Click Add Rule.
3. Choose whether any or all conditions must match.
4. Set a condition on the From header that matches the portal sender.
5. Set the action to move the message to a mailbox such as Portal Leads, then click OK.

Order matters. Mail stops applying rules to a message when it reaches a Stop Evaluating Rules action. Put the portal rule above any rule that sends mail elsewhere, or it may never run. Test it on two or three messages before you apply it to the whole backlog.

Screen each lead in under a minute

Filters sort mail. They cannot judge intent, so you need a screen. Keep it short. The point is to decide quickly which leads get a call and which get one question, not to research each buyer. Use this checklist when a lead lands.

• The message is copy-pasted and says nothing about a property, an area or a timeline.
• The phone number has the wrong length or no area code.
• The email address looks throwaway, or your reply bounces.
• The buyer skips your first question about timing or budget.
• The lead asks you to click a link, pay a fee or send documents before you have spoken.
• The property in the message sits in a different city than the buyer's stated area.

Use one screening question on every lead. Ask when they want to move, or whether they have talked to a lender. Send the same question each time, so replies are quick to write and easy to compare in your log. Do not ask for a Social Security number or bank details in a first reply.

Write one screening reply you can reuse

A reply template saves minutes on every lead. Keep one short screening reply in a note, then dictate it when you need it. Hold fn and speak. Lazur types clean, formatted text at the cursor in any app, and you can save the question as a snippet so you do not retype it.

Keep the reply plain. Name the property, ask one question and offer one next step. A long pitch to a lead that might be fake wastes your best hour. Send the reply within the hour when you can, because the HBR point about slow response is the reason this matters.

Track what each lead really costs in Google Sheets

A log turns a feeling into a number. Make one row per lead. The columns below cover what you need to judge a portal after a full month.

Then add the math. Use =SUM(C:C) for total spend and =COUNTIF(E:E,"Yes") for real conversations. Divide total spend by real conversations to get your cost per real conversation. Put that formula in a cell at the top, and check it every Friday.

Watch for text in number cells. If a price looks right but the total is off, the cell probably holds text. Re-enter the value as a number. You can hold ⌥ ⌘ and ask Lazur to explain a formula on screen, and it answers out loud.

Talk to the leads that are real

The goal is not to ignore leads. The goal is to reach the good ones first and keep the bad ones cheap. Screen in a batch, call the real ones while they are warm and log the rest. A portal earns its fee only when the real conversations justify the cost per real conversation you calculated.

Mistakes that make fake leads more expensive

• Blocking the portal's sender address, which can hide real leads and client mail.
• Deleting leads with a filter before you have read the label for a full month.
• Judging a source by one bad week instead of a month of logged rows.
• Sending a long pitch to every lead, which slows replies to real buyers.
• Pasting lead details into a personal email or an AI tool your brokerage has not approved.
• Assuming Zillow will refund a bad lead. Its public page does not describe refunds, so ask in writing.

Regulated work needs more care. Lawyers, nurses and accountants have strict rules on client and patient data. Realtors also handle personal information, so follow your brokerage's policy on client data before you use any AI tool or move lead details between apps.

What to ask Zillow about invalid leads

Zillow's public Premier Agent page gives the cost per connection. It does not describe lead credits, refunds or how invalid leads are handled. It also does not say whether a lead can be shared with competing agents. Check the pricing page and your account help for those answers, then ask your account contact in writing.

Bring your log. A dated list of leads, with a short reason for each junk call, is far more useful than a general complaint. It also gives you a record if you later ask for a credit.

Where Lazur fits in this routine

Lazur is a voice assistant for the Mac that lives in the notch. Hold ⌥ ⌘ to ask about anything on screen, and Lazur answers out loud. Ask where something is and Lazur circles it on your screen. Ask how to do something and Lazur guides you one click at a time, waiting for each click.

Lazur does not click buttons, edit files or change your Gmail settings for you. It cannot tell you whether a buyer is real. You still make the screen call. Lazur helps you find Block sender, walk through the filter, dictate replies and explain a formula in your sheet.

Lazur sees your screen and listens only while you hold the shortcut. Audio and the screenshot go to AI providers to answer you and are not stored. Content is never used to train AI models. Your brokerage's rules still apply to client data. A free trial with no credit card is available, and you can compare the plans on the pricing page.
