A buyer calls you on a Tuesday. She wants three bedrooms, two baths, a yard, one school district, and a price ceiling she already worked out with her lender. You promise to send anything that fits.
Then a closing and an inspection take up your week. On Friday you finally email her a match. It’s already pending.
The follow-up lived in your head and on a to-do list. Nothing on your website was doing that job while you were busy.
A saved search does that job. It is a stored set of listing criteria that emails a buyer automatically when a new or updated listing matches it, so the buyer never has to run the same search twice.
Many buyers start the search on their own. In the NAR 2024 Profile of Home Buyers and Sellers (buyers who purchased between July 2023 and June 2024), 43% said their first step was looking at properties online. 21% said their first step was contacting an agent. Those buyers searched for a median of 10 weeks. (NAR’s published highlights give no figure for how many buyers use saved searches, so I can’t give you that number.)
So a lot of that searching can happen without you. Saved searches on a real estate website can do it for her, and they run either on your site or on a portal.
Who holds the buyer’s attention, you or the portal
Zillow’s help center (page updated December 2023) says the visitor is prompted to sign in, name the search, and set how often updates arrive. Redfin puts the account first. Its help page on saved searches (updated September 2022) tells the buyer to create an account and log in before she can save a search.
Every saved search your buyer builds there sits in her Zillow or Redfin account. In my view, the portal gains the most here. It sends the alert, and her habit of opening it and clicking through stays with the portal, even if she already works with you.
On your own site, the email comes from you and the click lands on your listing page. The criteria also tell you what she wants in her own words: the area, the beds, the top price.
Some IDX saved search setups make the visitor register first. Since version 7.2.2 (per the plugin’s changelog), MLS Import has saved searches in its standalone mode only. The visitor gives a name and an email and doesn’t create an account. Nothing is sent until she clicks a confirmation email. The site owner gets an email when she confirms, and the searches appear in a plain wp-admin list (name, email, criteria, status, last sent). After that, the site sends at most one email a day, and only when imports added or updated a matching listing since the day before. No match means no email.
Confirmation is consent
A confirmation click tells you she wants these emails.
The law doesn’t ask for that click. The FTC’s CAN-SPAM Act: A Compliance Guide for Business says you don’t need to get members’ consent to send them marketing emails. The rules the guide does spell out include letting people opt out. A confirmation step is your own choice.
Your saved search email alerts still fall under that law. The FTC’s list of “transactional or relationship” messages is short, and the guide says the law reads those categories narrowly. A new-listings email doesn’t fit any of them. I read it as commercial email, whether Zillow sends it or your one-agent WordPress site does.
Every alert needs your valid postal address and an unsubscribe that works. The guide says the opt-out must keep working for at least 30 days after you send, and you must honor a request within 10 business days. Each email that breaks the rules can cost up to $53,088 (the FTC’s figure after its January 2024 inflation update).
The confirmation click makes it hard to sign up by accident. The unsubscribe link makes it easy to leave.
An alert is only as good as the feed behind it
Zillow’s help page on email types consumers can receive (updated December 2023) says a saved search for “sale listings in Seattle” will not generate an email at all. A narrower search, one ZIP code with a price range, will. And when a search is too wide, the email shows “a randomized collection of all available results.”
So on Zillow, how the search is set up changes what the email shows. Property alerts for buyers on your own site have a separate weak point, and that’s your data. An alert can only send what’s in your listing feed at the moment it runs. If a price drop hasn’t reached your site yet, the email can’t include it. If a sold home still shows as active, she gets excited about a house she can’t buy.
Before real estate listing alerts do your follow-up, test the feed. Pick a listing in your market that changed price this week and check whether your site shows the new price.
None of this replaces a phone call. Saved searches on your real estate website are help for the weeks you can’t follow up by hand, and your buyer still needs to hear your voice.
This week, ask your three most active buyers where their listing alerts come from. If they say Zillow or Redfin, those alerts come from the portal, not from you. Offer to set up the same criteria on your own site, then think about what that lead should turn into once they’re back on your site.
