How to Send Mass Text Messages to Customers the Right Way
Knowing how to send mass text messages to customers is one of the most valuable skills a business owner can have. Bulk SMS (text message) campaigns reach 98% of recipients, produce response rates 10 times higher than email and cost a fraction of any other marketing channel. However, there is a right way and a wrong way to do it.
The wrong way, buying a phone list and mass texting from your personal phone, leads to fines, blocking by carriers (the phone companies) and possibly lawsuits. The right way uses a proper platform, legal consent, careful targeting and compliant messages. This guide explains the complete setup.
What Is Mass Text Messaging?
Mass text messaging (also called bulk SMS or broadcast texting) means sending the same or a similar text message to a large group of people through a business texting platform. Unlike personal texts sent one at a time, mass texting uses application-to-person (A2P) messaging, meaning texts sent from software, to reach hundreds or thousands of people with one send.
Common use cases include:
- Promotional campaigns: Flash sales, discount codes, new product launches
- Event announcements: Store openings, webinars, community events
- Urgent notifications: Weather closures, schedule changes, emergency alerts
- Appointment reminders: Reducing missed appointments across your entire schedule
- Customer surveys: Net Promoter Score (NPS) ratings, feedback requests, satisfaction polls
- Political outreach: Voter contact, get-out-the-vote (GOTV) reminders, volunteer coordination
Step 1: Choose a Mass Texting Platform
You cannot send mass texts from your personal phone. Carriers will flag and block your number within hours, and you would have no opt-out management, no compliance tools and no reporting.
A proper mass text messaging service provides:
- 10DLC registration: Carrier registration of your number, required for all business A2P texting
- Contact management: Import, sort and organize your subscriber list
- Automated opt-out processing: STOP requests handled automatically
- Personalization: Merge fields that insert each person's name, location or other details
- Scheduling: Send at the best times or schedule future campaigns
- Analytics: Reports on delivery rates, response rates and link clicks
- Compliance tools: Consent tracking, sending-hour limits and Do Not Call (DNC) list checks
CampaignCNX+ provides all of this in a single SMS marketing platform, with pricing that works for businesses of any size.
Step 2: Build Your Subscriber List (Legally)
Every person on your mass texting list must have given explicit consent to receive texts from your business. You can build your list in these ways:
Web forms: Add an SMS opt-in checkbox to your website, checkout page or other web pages. Include the required consent language (business name, message frequency, data rates, STOP instructions).
Keywords: Promote a text-to-join keyword: "Text DEALS to [Number] for exclusive offers." Place it on signs, social media, packaging and receipts.
For a complete overview, read how businesses text their customers.
In-person collection: Use a sign-up form on a tablet at events, trade shows and your checkout counter. Always include consent language.
Cross-promotion: Ask your email subscribers and social media followers to join your text list with an incentive.
Never buy phone lists, copy numbers from the internet or add contacts without their knowledge. These practices violate the TCPA (the federal Telephone Consumer Protection Act) and will get your account suspended.
Step 3: Register for 10DLC
Before sending your first mass text, you need 10DLC registration:
- Brand registration: Verify your business identity with The Campaign Registry. On CampaignCNX+, 10DLC registration is a one-time $75 fee, and we file it for you
- Campaign registration: Register your use case (marketing, notifications and so on)
- Carrier approval (1 to 5 business days): Carriers review and approve your campaign
Without registration, your messages will be filtered or blocked. Most platforms (including CampaignCNX+) handle registration as part of account setup.
Step 4: Create Your First Campaign
Before anyone gets a text
- Ask in writingThe form or sheet says plainly that they agree to receive texts from you.
- Keep the recordNote the date and where each person signed up.
- Send at reasonable hoursQuiet-hours scheduling keeps texts out of the night.
- Honor STOPA STOP reply is handled automatically.
Write Your Message
Keep the message short and clear, and give the reader one thing to do:
- Identify yourself: Start with your business name
- State the value: Explain the benefit to the recipient
- Include a call to action: Tell them what to do (click, reply or visit)
- Add opt-out instructions: "Reply STOP to unsubscribe" (required on first contact)
Example:
"[Store Name]: Summer clearance starts now. Up to 50% off everything online. Shop: [Link]. This weekend only. Reply STOP to opt out."
Personalize It
Use merge fields to include the recipient's name: "Hi {FirstName}, [Store Name] has a special offer just for you..." Personalized texts see 15 to 25% higher engagement than generic mass texts.
Group Your Audience
Sending the same message to everyone wastes texts on people it does not suit. Group your list by:
- Purchase history: Past buyers versus potential customers
- Location: City, state or ZIP code
- Engagement level: Active subscribers versus inactive contacts
- Preferences: Product interests, preferred message frequency
Time It Right
Best sending times for mass business texts:
- Retail and online stores: Tuesday to Thursday, 10 AM to 2 PM
- Restaurants: Specials for that day at 10 to 11 AM, and dinner promotions at 3 to 4 PM
- Services: Monday to Wednesday, 9 AM to 12 PM
- Never: Before 8 AM or after 9 PM (TCPA violation)
Step 5: Send and Monitor
After sending, track these measures:
- Delivery rate: Should be 95% or higher. Lower rates suggest carrier filtering or bad contact data.
- Open or read rate: Texts average 98%. If responses are low, your content may not interest your readers.
- Click-through rate: For texts with links, track clicks. The average is 15 to 20%.
- Response rate: For texts asking for replies, 20 to 30% is good.
- Opt-out rate: Keep below 2% per campaign. Higher rates suggest you text too often or target poorly.
- Conversion rate: The share of recipients who took the desired action (purchased, booked, signed up).
Mass Texting Compliance Checklist
Before you send any bulk SMS campaign, confirm the following:
- Every recipient has given TCPA-compliant consent
- Your 10DLC registration is active and approved
- Your message includes your business name
- Opt-out instructions are included (first contact with new subscribers)
- You are sending between 8 AM and 9 PM in the recipient's time zone
- Your suppression list (opt-out list) has been applied
- No prohibited content (check carrier policies)
- No generic link shorteners (use full web addresses or short links under your own brand)
How Much Does Mass Texting Cost?
What one text costs on each plan
On CampaignCNX+, each message segment (each 160-character part of a text) costs $0.06 on pay-as-you-go, or $0.035 to $0.055 on a monthly plan. For a campaign of 1,000 recipients with a standard-length message:
- Cost per campaign: about $60 on pay-as-you-go
- Monthly cost (4 to 8 campaigns): about $240 to $480 on pay-as-you-go, or less on a monthly plan, plus $5 a month for your number
- Return on investment (ROI): depends on your list and your offer, so track the sales from each campaign to measure it
Compare that with Facebook ads ($5 to $15 per thousand views, 1 to 2% click rate) or direct mail ($0.50 to $2.00 per piece, 1 to 5% response rate). Per response, mass texting costs far less than either.
Plan and Send Your First Mass Text Campaign
Mass text messaging is not complicated once you have the right platform and follow the rules. Build a consented list, write clear messages, send at good times and track your results. Even 50 to 100 subscribers is enough to see results from your first messages.
CampaignCNX+ keeps the process simple. You import your contacts, write your message, choose your audience and send. Compliance tools, reporting and two-way messaging, so customers can reply, are built in. Start with 100 free SMS and set up your first bulk SMS campaign. You get 100 free SMS to start, your number is $5 a month, and we file the carrier approval for you. That review usually takes about 3 business days for a toll-free number.
