Christmas is the busiest season for most businesses, a period marked by special offers and holiday discounts. With brands sending a massive volume of messages and consumers actively shopping, competition for attention is intense. According to an Adobe study, U.S. customers are expected to spend approximately $253.4 billion during this holiday season.

However, the problem with many businesses is that they still send text messages to landline numbers, VoIP numbers, or invalid numbers without even knowing it. It can be the reason for wasted budget, low delivery rates, and poor results. Now, the real question is how to fix these issues.

The simple answer to this is, clean your contact list before you start your Christmas campaign. This is where Landline Remover helps you. It identifies mobile numbers, VoIP numbers, and landline numbers, removes risky contacts, and stays compliant with TCPA and DNC rules.

In this blog, we will discuss how filtering out landline and VoIP numbers can save you money and time. Let’s get started.

What is the Real Problem During the Christmas Campaign?

The holiday season drives up costs for advertising, inventory, shipping, promotions, and SMS. Yet, many businesses inadvertently waste this budget by sending messages to numbers that can’t receive them, like VoIP numbers, invalid numbers, numbers belonging to known TCPA litigators, and people registered in DNC lists. 

The result is wasted spending, abysmal engagement, and the serious risk of carrier flags and TCPA fines, which can cost $500–$1,500 per violation.

Without a clean list, your Christmas campaign won’t just underperform; it could become a significant liability.

What Happens When Your Contact List Isn’t Filtered?

Let’s take a quick look at what happens when you don’t filter your contact list.

Of course, you don’t want your Christmas promotions to fail just because the message never reached the customer.

Why Filtering Landline and VoIP Numbers is Essential for Christmas Marketing

Here are a few reasons that show why filtering landline and VoIP numbers is essential for Christmas marketing.

1. To Avoid Sending SMS to Landline Numbers

   Landline numbers cannot receive SMS. Therefore, every message you send to the landline numbers means you lose money.

   For example,

   If you are sending 10,000 SMS, and among them 2,500 numbers are landlines, it means you’re wasting money on leads who cannot receive your messaging!

2. Deliver Messages Faster

   A clean contact list means few errors and faster sending. This specifically matters during:

   • Seasonal sales
   • Last-minute discount drops
   • 12-day holiday promotions
   • Weekend flash deals

   A clean list ensures your message reaches your customer’s phone at the right time.

3. To Avoid Sending SMS to VoIP Numbers

   VoIP numbers come with risks such as

   • It may belong to bots
   • Often used in fraud
   • Frequently used by TCPA litigators
   • May trigger carrier blocking

   Filtering these numbers is essential for a secure and effective Christmas SMS campaign.

4. Improve Targeting Accuracy

   When you filter the contact list, you can target real mobile users and genuine buyers. In short, better targeting = higher clicks + higher conversions.

How Filtering Landline and VoIP Numbers Helps You Save Money and Time

Filtering landline, VoIP, risky, and invalid numbers before you launch your Christmas campaign is the smartest way to save time and money and improve results. Let’s check out how it helps.

1. You Save Money on Every SMS You Send

   Generally, SMS marketing platforms charge for every single text, whether it gets delivered or not. When your list contains landline numbers, VoIP numbers, or fake numbers, you instantly lose money.

   For example,

   If your Christmas list has 8,000 contacts and 2,000 are landline/VoIP numbers, then 2,000 * $0.01 per SMS = $20 wasted per campaign.

   If you run 10 holiday campaigns, you will lose $200.

   Filtering numbers protects your budget.

2. You Avoid Fraud and Risky Numbers

   VoIP numbers are usually connected to fake leads, bots, fraud attempts, spam traps, and TCPA litigators who intentionally trap businesses.

   If you filter these numbers, it helps you reduce the risk of carrier blocking, minimize spam complaints, avoid expensive TCPA fines, and protect your brand reputation. In short, it helps you in following TCPA and DNC compliance.

3. Your Messages Deliver Faster

   Having a clean list means fewer failed messages, which offers faster throughput. It is important specifically during time-sensitive holiday promotions like

   • “Last 24 Hours Before Christmas” sale
   • “Midnight Christmas Eve Deal”
   • “Flash 2-Hour Christmas Discount”

   In short, if the error rate is lower, your SMS platform will push your messages through.

4. You Improve Targeting and Can Reach Real Buyers

   When you remove landline and VoIP numbers, you will be left with a high-quality list of real mobile users.

   It means:

   • Better open rate
   • Higher click-through rate
   • More conversion
   • More holiday sales

   During Christmas, every message matters, and clean targeting dramatically boosts results.

5. You Save Time for Your Marketing Team

   If you have a bad contact list, it drains time because your team has to deal with complaints, handle delivery errors, fix low engagement issues, troubleshoot problems, and rerun campaigns.

   Having a clean list means your team works smarter, not harder. You simply upload your clean list, send messages, and enjoy smooth holiday performance.

6. Avoid Technical Issues

   Landline and VoIP numbers cause carrier rejection, failed routes, higher bounce rates, and slower campaign processing. When you use the phone number validation tools and filter numbers, you remove these issues. As a result, your Christmas campaign runs smoothly and efficiently.

7. You Stay Compliant With Fewer Headaches

   Many VoIP numbers belong to litigators or people waiting to file TCPA complaints. When you filter them, it reduces your risk, keeps your SMS campaign safe, and protects you from $500 to $1500 fines per text.

   When your list is clean, you get peace of mind, especially during the high-volume holiday season.

Christmas Campaign Tips That Save You Money and Time

Christmas is the biggest shopping season of the year, and that’s why your marketing should feel warm, helpful, and timely. Moreover, your Christmas SMS campaign becomes more effective when your contact list contains only real and active mobile numbers. Here are some simple and actionable tips that make your SMS campaign faster and perform better.

1. Send Time-Sensitive Holiday Alerts With Confidence

   If your contact list contains only mobile numbers, your messages actually reach people. It is specifically important during Christmas because many offers are time-sensitive.

   You can send last-minute discounts, flash sales, or extended shopping hours messages without worrying about failed SMS. This way, your messages reach real customers, not landlines that cannot receive texts. It means faster responses and better results.

2. Personalize Your Message Based On Real Customer Activity

   Landline or VoIP numbers do not tell you anything about customer behavior. However, mobile numbers show clicks, opens, and replies whenever people interact with your SMS. It helps you send more personal Christmas SMS like “Recommended gifts for you.” Personal messages feel more special during Christmas. Customers are more likely to buy when the messages feel relevant to them.

3. Run Delivery and Pickup Notifications Without Failures

   People wait for their Christmas gifts to arrive on time. That’s why delivery updates are important. SMS works perfectly for shipping alerts like “out for delivery” or “your order is ready for pickup.” If your list contains landline numbers, these important updates fail. But, with the clean mobile list, every message reaches the right person. It keeps your customers informed and reduces stress during the busy holiday season.

4. Optimize Timing Based On Real Engagement

   Mobile numbers provide accurate data on customer response times, helping you identify the optimal moments to send Christmas deals, whether mornings, evenings, weekdays, or weekends. If your list includes landline numbers, this timing data becomes skewed. A clean list, by contrast, reveals genuine customer behavior, enabling better timing and driving more sales during the critical Christmas rush.

5. Promote Urgent Stock Alerts More Effectively

   During Christmas, people buy quickly, so popular items sell out fast. SMS is perfect for sending a “Only a few items left!” alert or “Selling fast!” updates. These alerts matter only if people can receive them instantly on their phones. Landline numbers make these messages bounce, which wastes time and money. If you have a mobile-only list, it ensures that your messages reach real buyers before the stock is gone.

6. Reduce SMS Cost During Christmas Traffic Peaks

   Businesses send more messages during Christmas than at any other time of the year. Every SMS you send costs money, so sending messages to landline numbers is a direct loss. If you use a phone number validation tool like Landline Remover, you can filter out landline and VoIP numbers, which prevents wasted spending. If you have a clean list, you can use your budget wisely and reach more real customers. It makes your Christmas campaign more profitable.

7. Improve Customer Experience With Fewer Failed Messages

   Christmas shoppers expect fast communication. If they miss an offer, tracking link, or reminder, they might feel frustrated. Failed messages often happen when landline or VoIP numbers are in your list. A clean list means more messages delivered and fewer unhappy customers. It offers a smooth and friendly user experience during the holiday season.

8. Run Better Follow-Up Sequences

   Christmas marketing requires multiple follow-up texts, such as “Still interested?” or “Your cart is waiting.” These sequences only work when the first message is delivered. If the number is a landline, the whole sequence stops. A mobile-only list keeps the entire flow running smoothly. It helps convert more shoppers who need a small push before they buy.

   The good news is, this filtering doesn’t have to be manual. A tool like Landline Remover handles the filtering for you:
