How to Text Customers From Your Business

Your customers check their phones 96 times a day. Their email inbox has 47 unread messages. Your carefully crafted email newsletter? Buried under a Costco receipt and two LinkedIn notifications they will never open.

Text messaging changes this equation entirely. Text messages have a 98% open rate, compared to roughly 20% for email. Most texts are read within three minutes of delivery. For businesses that need to reach customers quickly and reliably — appointment reminders, order updates, follow-ups, promotions — texting is not just better than email. It is a different category of communication.

But texting customers from a business is not the same as texting a friend. There are legal requirements, technical considerations, and etiquette rules that separate professional business texting from spam. This guide covers all of it — no technical background required.

Why Business Texting Works Better Than Email

Email marketing was revolutionary in 2005. In 2026, the average professional receives over 120 emails per day. The competition for attention in an email inbox is fierce, and most marketing emails never get opened.

Text messages bypass the inbox entirely. They land directly on the lock screen. There is no spam folder for texts. There is no algorithm deciding whether your message gets shown. When you send a text, it arrives.

Here is how the numbers compare:

• Open rate: Text messages see 98% open rates. Email averages around 20%.
• Response time: The average text response comes within 90 seconds. Email responses average 90 minutes — when they come at all.
• Click-through rate: Links in text messages get clicked 19% of the time. Email links average 2.5%.
• Opt-out rate: Text opt-out rates average 1-2%. Email unsubscribe rates hover around 0.5%, but that is misleading because most people just stop opening rather than formally unsubscribing.

These numbers tell a clear story: if you need a customer to actually see and act on your message, text wins.

When Texting Makes Sense (and When It Doesn’t)

Text messaging is ideal for:

• Time-sensitive communications — appointment reminders, delivery updates, urgent notices
• Short, actionable messages — confirm your appointment, use this code, your order shipped
• Personal follow-ups — thank you messages after a purchase, check-ins after a service
• Promotions with deadlines — flash sales, limited-time offers, event invitations

Text messaging is not ideal for:

• Long-form content — newsletters, detailed product announcements, educational series
• First contact with cold leads — texting someone who has never interacted with your business feels invasive
• Complex information — anything requiring more than a paragraph of explanation

The rule of thumb: if your message is under 300 characters and benefits from being read immediately, text it. If it is longer or does not have urgency, email it.

Setting Up Professional Business Texting

The days of texting customers from your personal phone are over. Using a personal number creates problems: you cannot track messages, multiple team members cannot respond, and your personal phone number ends up on every customer’s contact list.

Professional business texting means using a dedicated business number through a messaging platform. This gives you:

• A separate business identity — customers see your business number, not your personal cell
• Team access — multiple people can send and receive from the same number
• Message history — every conversation is logged and searchable
• Compliance tools — automatic opt-out handling, quiet hours, consent tracking
• Templates — reusable message formats for common communications

Choosing Between SMS and iMessage

If your customers are in the United States, there is a significant choice to make: SMS or iMessage.

SMS (the green bubble) works on every phone. Android, iPhone, flip phones — any device with a cellular connection can receive SMS. The downside: SMS messages are often filtered by carriers, delivery can take several seconds, and there are no read receipts.

iMessage (the blue bubble) only works between Apple devices, but roughly 57% of US smartphone users have iPhones. iMessage delivers faster (typically under two seconds), shows read receipts, supports richer formatting, and is not subject to carrier filtering. Recipients perceive iMessage as more trustworthy — it is a message from a real number, not a shortcode.

The ideal approach is a platform that automatically detects whether a recipient has iMessage and routes accordingly — iMessage when available, SMS as a fallback. This is exactly what senderZ’s Workspace does: you send one message, and the platform figures out the best channel for each recipient.

What You Need Before Sending Your First Text

Before you text a single customer, you need three things:

1. A dedicated business phone number — separate from your personal number
2. Written consent from every recipient — this is a legal requirement, not a suggestion
3. A messaging platform with compliance tools — to handle opt-outs, quiet hours, and consent logging automatically

That third point is crucial. Manually managing who has opted in, who has opted out, and when you can legally send messages is a recipe for expensive mistakes. A proper platform handles all of this for you.

Compliance: The Legal Side of Business Texting

This is the section most guides gloss over, and it is the one that matters most. The Telephone Consumer Protection Act (TCPA) and the Cellular Telecommunications Industry Association (CTIA) guidelines govern business texting in the United States. Violating them can result in fines of $500 to $1,500 per unsolicited message.

That is per message. Send 1,000 texts without proper consent? That is potentially $1.5 million in fines.

Getting Consent (Opt-In)

The law requires express written consent before you send marketing texts to a customer. Verbal consent is not enough. “They gave me their phone number” is not consent to text them promotions.

Valid opt-in methods include:

• A checkbox on a form — “I agree to receive text messages from [Business Name]” (cannot be pre-checked)
• A text keyword — “Text JOIN to [your number] to receive updates”
• A website signup — a form specifically for text message subscriptions with clear language about what they will receive
• Point of sale — asking customers to opt in during checkout, with written documentation

Every opt-in must clearly state:

1. What types of messages they will receive
2. How often they will receive them
3. That message and data rates may apply
4. How to opt out (reply STOP)

Keep a record of every consent — when it was given, how it was given, and what the customer agreed to. If a customer ever disputes that they opted in, you need documentation. Platforms like senderZ handle consent logging automatically, creating an audit trail for every phone number.

Handling STOP Messages (Opt-Out)

When a customer texts STOP, you must immediately stop sending them messages. Not “after the current campaign finishes.” Not “after one more follow-up.” Immediately.

The law also requires you to honor these variations: STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, and QUIT. When someone sends any of these words, they are opting out.

After receiving a STOP message, you should send exactly one confirmation: “You have been unsubscribed from [Business Name] messages. Reply START to re-subscribe.”

Then — and this is important — do not contact that number again unless they explicitly opt back in by texting START.

This is where manual management falls apart. Keeping track of who has opted out across every campaign, every team member, and every phone number is nearly impossible without a system. With senderZ’s built-in opt-out handling, STOP messages are processed automatically in real time. The system blocks any future messages to that number before a human even sees the STOP request.

Quiet Hours

The TCPA restricts when you can send marketing messages. The general rule: no marketing texts before 8:00 AM or after 8:00 PM in the recipient’s local time zone.

Note: this is the recipient’s time zone, not yours. If you are in California and your customer is in New York, you cannot send them a marketing text at 5:30 PM Pacific (8:30 PM Eastern).

Transactional messages — appointment reminders, order confirmations, verification codes — have more flexibility, but sending a transactional text at 2:00 AM is still bad practice even if technically legal.

A good messaging platform enforces quiet hours automatically. When you schedule a campaign or send a batch of messages, the system holds any messages that would land during quiet hours and delivers them at 8:00 AM the next morning in each recipient’s time zone.

Writing Business Texts That Get Results

Compliance keeps you out of legal trouble. Good writing gets you results.

Keep It Short

You have about 160 characters before an SMS gets split into multiple messages. Even with iMessage (which supports longer messages), shorter is better. Your customer is reading this on a phone screen while doing something else. Get to the point.

Too long: “Hi Sarah! We wanted to reach out to let you know that we have some exciting new arrivals at the store this week and we thought you might be interested in checking them out when you have a chance!”

Just right: “Hi Sarah — new spring collection just dropped. 15% off this weekend with code SPRING15. Shop: [link]“

Include a Clear Call to Action

Every business text should make it obvious what you want the customer to do. Reply to confirm. Click this link. Use this code. Come in before Friday.

• “Reply YES to confirm your appointment for Thursday at 2 PM”
• “Your order shipped! Track it here: [link]”
• “Flash sale — 20% off all services today only. Book now: [link]“

Personalize When Possible

Using a customer’s first name increases response rates. So does referencing their specific situation — the product they ordered, the service they booked, the location they visited.

Message templates with variables make this easy at scale. Instead of writing individual messages, you create a template like: “Hi [first_name], just a reminder about your [service] appointment tomorrow at [time].” The platform fills in the details for each recipient.

Timing Matters

The best times to send business texts vary by industry, but general guidelines apply:

• Appointment reminders: 24 hours before, then 2 hours before
• Promotional messages: Tuesday through Thursday, 10:00 AM to 2:00 PM local time
• Follow-ups after a purchase: Same day or next business day
• Abandoned cart reminders: 1 hour after abandonment, then 24 hours later

Avoid Mondays (people are catching up from the weekend) and Fridays after 3:00 PM (people have mentally checked out).

Match the Tone to Your Brand

Business texting should sound like a professional conversation — not a form letter, and not a text from a college roommate.

Too formal: “Dear Valued Customer, We wish to inform you that your scheduled appointment has been confirmed for the aforementioned date.”

Too casual: “hey!! ur appt is tmrw dont forget lol 😂”

Just right: “Hi David — your haircut appointment is confirmed for tomorrow at 3 PM. Reply C to cancel or R to reschedule.”

Building Your Contact List the Right Way

The fastest way to get in trouble with business texting is to buy a phone number list. Do not do this. Ever. Those numbers did not consent to receive your messages, and texting them violates the TCPA.

Instead, build your list organically:

At the Point of Sale

When a customer makes a purchase, ask if they would like to receive text updates. Frame it as a benefit: “Would you like to get a text when we have sales? We only send about two per month.”

On Your Website

Add a text subscription option to your website. A simple form: name, phone number, and a clear consent statement. Put it on your contact page, checkout page, and as a pop-up for returning visitors.

Through a Keyword

Advertise a text keyword in your store, on social media, or in email signatures: “Text DEALS to [your number] for exclusive offers.” This is self-qualifying — only interested people will text you.

From Existing Email Subscribers

If you have an email list, send a campaign inviting them to opt in to texts. “Get time-sensitive updates faster — join our text list.” This converts your most engaged email subscribers into text subscribers.

Social Media

Post your text number or keyword on Instagram, Facebook, and other platforms where your customers spend time. “Want first access to new arrivals? Text VIP to [number].”

Measuring What Works

Like any marketing channel, business texting should be measured and optimized. Key metrics to track:

• Delivery rate — what percentage of messages actually reach the recipient
• Open rate — for iMessage, you can see read receipts; for SMS, you estimate based on link clicks
• Click-through rate — if your message includes a link, what percentage of recipients click it
• Response rate — for two-way conversations, how often do customers reply
• Opt-out rate — how many people unsubscribe after each campaign
• Conversion rate — how many recipients take the desired action (book, buy, visit)

If your opt-out rate spikes after a particular campaign, it tells you something went wrong — too frequent, wrong tone, irrelevant offer. Adjust and learn.

senderZ provides analytics through the Workspace dashboard, showing delivery rates, read receipts (for iMessage), and response metrics for every message and campaign.

Common Mistakes to Avoid

Texting too often. Two to four messages per month is the sweet spot for most businesses. More than that and opt-outs increase sharply.

No opt-out option. Every marketing text must include a way to opt out. “Reply STOP to unsubscribe” should appear in your first message to each subscriber and periodically after that.

Ignoring replies. When a customer responds to your text, they expect a response. If you send one-way blasts and never check replies, you are wasting the biggest advantage of texting: it is a two-way channel.

Using a personal phone. It seems easier, but there is no compliance tracking, no team access, no message history, and your personal number is exposed.

Sending during quiet hours. An 11:00 PM promotional text is not just illegal — it is the fastest way to get someone to opt out permanently.

Getting Started

Setting up professional business texting does not require a technical team. Modern messaging platforms are designed for business owners who want to communicate with customers without learning to code.

With senderZ, you can:

1. Get a dedicated business number
2. Import your existing contact list (with documented consent)
3. Create message templates for your most common communications
4. Set up automated appointment reminders
5. Launch your first campaign — all from a simple dashboard

The platform handles compliance automatically: opt-out processing, quiet hours enforcement, consent logging, and delivery optimization. You focus on what to say. The system handles how it gets there.

If you are still relying on email alone to reach your customers, you are leaving engagement on the table. Text messaging is not replacing email — it is filling the gap that email cannot. The urgent message. The time-sensitive offer. The appointment reminder that actually gets seen.

Your customers are already on their phones. Meet them there.
