Sending property updates via SMS has become a normal part of real estate marketing. Real estate agents can send text messages about new listings, open house reminders, follow-ups, price drops, and more. It helps them stay quick and visible. However, a silent problem lies within many real estate contact lists: some contacts cannot receive text messages at all.

Now, imagine you’re a real estate agent, and you have listed a beautiful property. It has a great location, a fair price, and strong demand. You send a property update text message to your contact list and wait for replies. Hours pass, but you don’t get any answers. You start wondering whether the price is too high or the market is slow. Are people not interested anymore?

However, what if the real issue is not the property at all? What if your message never reached a real person? It could mean you’re sending text messages to landlines. Every time you send a property update to these numbers, your message disappears: along with your money, time, and opportunity.

In this blog, we will shed light on why sending property updates to landline contacts is hurting your real estate business, how much it can cost you, and how to stop it. So, without further ado, let’s get started.

What Role Does SMS Play in Modern Real Estate Communication?

Real estate is a fast-moving business. Buyers want instant updates, and sellers expect quick responses. Agents don’t have time to wait for emails to be opened or phone calls to be returned. That’s why SMS works so well.

Text messages are read quickly, easy to respond to, and ideal for sending short, urgent updates. Real estate agents commonly use SMS to send new property listings, open house reminders, price reduction alerts, follow-ups after inquiries, and appointment confirmations.

When SMS works, it works beautifully. However, it only works if the number on the other end can receive texts.

So, what is the hidden issue in real estate contact lists?

Read on to find out.

What’s the Hidden Issue in the Real Estate Property Contact List?

Most real estate agents don’t intentionally add landline numbers to their contact lists, but these numbers sneak in quietly over time.

How?

Here are some common culprits.

• Old CRM data that was imported years ago
• Website forms where people enter their home numbers
• Purchased or shared third-party lead lists
• Contacts added manually without verification

Therefore, over time, your contact list grows, but not every number in it is a mobile number. These landline numbers cannot receive SMS messages, which creates a serious problem that many agents don’t realize until it’s too late.

What Happens When You Send Property Updates to Landline Numbers?

SMS messages are designed specifically for mobile phones, while landlines are built for voice calls only. This raises an obvious question: what happens when you text a landline?

The message never reaches a person. There is no notification, no reply, and no chance of engagement. The most frustrating part is that your SMS platform still sends the message and charges you for it.

From the system’s perspective, the message was delivered successfully. From the customer’s perspective, it never existed. This is the gap where your money and opportunities vanish.

What’s the Real Cost of Sending Property Updates to Landline Contacts?

At first glance, a single failed message doesn’t seem expensive. However, the loss becomes very real when you look at the monthly and yearly totals.

Let’s understand this with a simple example:

It means monthly wasted SMS = 1,200 * 3 = 3,600.

Monthly wasted SMS cost = 3, 600 * $0.03 = $108

Yearly wasted cost = $108 * 12 = $1,296

This, however, is only the direct cost. It doesn’t include the far greater losses from missed deals, poor campaign decisions based on faulty data, or the valuable time spent analyzing incorrect metrics. For real estate agencies, this total loss is much higher.

Why Landline Messaging Hurts Real Estate More Than Other Industries?

Timing is everything in real estate: more so than in almost any other industry. A property update meant for today is useless tomorrow because buyers move fast. Listings get booked quickly, and price drops attract immediate attention.

If a buyer doesn’t see your message, they will see another agent’s. This means a single missed SMS can result in a missed showing, a lost buyer, or a deal that goes to a competitor. This is precisely why sending messages to landlines hurts real estate businesses more than those in slower-moving industries.

How Can Landline Numbers Manipulate Your SMS Campaign Results and Decisions?

Landline numbers do more than just waste money; they also corrupt your data. When reviewing campaign results, you’ll see a high number of “messages sent” but low replies and poor engagement rates.

This often leads to the wrong conclusions, such as “My message copy isn’t good,” “SMS doesn’t work for my audience,” or “People are not interested.”

However, the reality is different. The truth is that many people never received your messages at all. What you perceive as poor performance is entirely disconnected from reality.

This misleading data can lead to poor marketing decisions and unnecessary frustration. So, what’s the solution?

It’s simple: clean your contact list.

Why is Manual Contact Cleaning a Practical Solution?

Some agents attempt to clean their contact lists manually, scanning spreadsheets, guessing which numbers are landlines, and removing them one by one. However, this manual approach is not sustainable long-term.

It is far too time-consuming, prone to errors, and ineffective as new landlines are constantly being added. As a real estate professional, your focus should be on selling property, not cleaning data.

This is precisely why the problem requires an automated solution.

What is Landline Remover, and How Does it Solve This Problem?

Landline Remover is a specialized phone number validation tool that intelligently and reliably removes landline numbers from your contact list. It automatically scans your contacts, identifies landlines, removes them from your SMS campaigns, and ensures only valid mobile numbers remain.

This entire process happens before your campaigns are sent. In short, rather than correcting mistakes after the fact, Landline Remover prevents them from happening altogether.

Let’s compare the performance of your real estate SMS campaigns with and without Landline Remover:

A Real Property Update: Before and After Scenario

Before: Imagine sending a new listing update to 4,000 contacts. Without Landline Remover, your list might contain 800 landline numbers. You pay to send 4,000 messages, but receive low reply rates and waste your budget on unreachable contacts.

After: Now, integrate Landline Remover with your SMS platform. The tool cleans your list, leaving only 3,200 valid mobile numbers. You send fewer messages, but the results transform: reply rates increase, your budget is used efficiently, and you gain clear insight into your campaign’s true performance.

This demonstrates a key principle: sometimes, sending fewer messages leads to better results.
