Business Texting Etiquette: Rules for Customer Texts

Good business texting etiquette comes down to six rules: only text people who agreed to it, say who you are, keep it short, write like a polite person rather than a system, text at reasonable hours, and switch to a call when the topic needs one. Texting works because it is quick and low-pressure. Every rule here is about protecting that.

Texting reaches almost everyone. Pew Research Center's 2025 data shows 98% of U.S. adults own a cellphone and 91% own a smartphone. That reach is exactly why customers are protective of their text inbox, and why careless business texts get ignored, reported or blocked.

Rule 1: Have permission

Text customers who have agreed to hear from you: they texted you first, asked you to text them, or gave their mobile number on a form that said you would text. Marketing texts require prior express written consent. The CTIA Messaging Principles and Best Practices, which carriers use to judge business messaging, set out these expectations, and US carriers also require businesses texting from local numbers to register through The Campaign Registry (10DLC). See how to get consent to text customers and what 10DLC registration is.

Rule 2: Identify yourself

Your number may not be saved in their phone. Start the first message, and any message after a long gap, with your name and business:

Hi Maria, it's Kim from Summit Heating and Air.

In a back-and-forth conversation you do not need to repeat it every time.

Rule 3: Keep it short

• One topic per message
• Around 160 characters where possible, so it arrives as a single message
• The key fact (date, time, amount, question) near the start
• No long paragraphs; if it needs paragraphs, it might need an email or a call

Rule 4: Write like a person

Instead of	Write
"Your appointment has been scheduled for 10/09/2026 at 08:00."	"You're booked for Thu Oct 9, 8-10am."
"Please be advised that our technician is delayed."	"Rob is running about 30 min late, sorry!"
"Kindly remit payment at your earliest convenience."	"Invoice 1042 ($640) is due Monday. Pay here: [link]"
"URGENT!!! RESPOND NOW"	"Can you reply by 3 today so we can hold your slot?"

Use normal capitalization and punctuation. All caps reads as shouting. Avoid abbreviations your customers might not know.

Rule 5: Text at reasonable hours

Send non-urgent texts during business hours in the customer's time zone. Avoid texts before 8 a.m. or after 9 p.m.; that window mirrors federal limits on telephone solicitations to residential numbers (47 CFR 64.1200), and several states set their own limits on marketing texts. Hold after-hours replies until morning unless the customer is mid-conversation with you or it is urgent. More in how to get consent to text customers.

Rule 6: Know when to call instead

Switch to a phone call when:

• The customer is upset
• The topic is complicated or needs a decision with several options
• You are delivering bad news (cancellation, big price change, serious problem)
• A text conversation has gone back and forth more than a few times without resolution
• The information is sensitive

"This is easier to explain by phone. Can I call you in 5 minutes?"

Emojis, photos and links

Emojis. One friendly emoji in a casual thank-you can fit some brands. Avoid them in anything about money, complaints, health or bad news. When in doubt, leave them out.

Photos. Useful for showing a finished job, a part, or a problem the customer asked about. Ask before sending photos of anything personal, and avoid sending images of documents with sensitive details.

Links. Use your own website's full link where possible. Link shorteners that hide the destination are a common spam signal, and carriers may filter messages containing them. Do not send links in a first message to someone who has not heard from you before unless they asked for one.

Replying etiquette

• Reply promptly. Customers expect texts to be faster than email; aim for 15 to 60 minutes during business hours. See response-time standards by channel.
• Acknowledge even when you cannot answer yet. "Got it, checking with the tech and will reply by 2."
• Close the conversation. "Great, you're all set. Thanks Maria!" tells them nothing more is needed.
• Do not leave customers on "read." If a reply is not needed, a brief acknowledgment is still polite.

Team texting etiquette

When several people text from one business number:

• Sign messages with your first name in shared conversations so customers know who they are talking to
• Assign conversations so two people do not answer the same customer differently
• Use saved templates for common messages so tone is consistent
• Never move a customer conversation to a personal number

More in how a shared team text inbox works.

Opt-outs

Every customer must be able to stop texts at any time. Honor STOP, UNSUBSCRIBE, CANCEL, END and QUIT, and similar plain-language requests like "please stop texting me." Include "Reply STOP to opt out" in the first message to a new contact and in marketing messages. See handling STOP and opt-outs.

Example: a well-run text conversation

Business: Hi Maria, it's Kim from Summit Heating and Air. Your AC tune-up is booked for Thu Oct 9, 8-10am. Reply C to confirm or R to reschedule. Reply STOP to opt out.

Maria: R please, something came up

Business: No problem! I have Fri 8-10am or Mon 1-3pm. Which works?

Maria: Monday

Business: Done, you're set for Mon Oct 13, 1-3pm. Thanks Maria! - Kim

Short, clear, identifies the business, offers specific options, and closes the loop.

Texting etiquette checklist

• Customer agreed to texts
• Business name in first message
• One topic, under about 160 characters
• Specific date, time or amount
• Sent during business hours
• Opt-out language for new contacts
• Reply within your team's target
• Switch to a call for complex or bad news

Common texting mistakes small businesses make

• Texting from a personal phone. Customers save the employee's number, the conversation leaves when the employee does, and opt-outs are not tracked. Use the business number.
• Mass texts that look personal. A message that starts "Hi friend!" sent to 300 people fools nobody. Either personalize properly or write it as a clear announcement from the business.
• Over-texting. A booking confirmation, two reminders, an on-the-way text, a completion text, a review request and a promotion in one week is too many. Combine or cut.
• Answering the wrong question. Read the whole message before replying, especially in a busy shared inbox.
• Arguing by text. If a conversation turns tense, call. Tone is easy to misread in short messages.
• Forgetting the message is permanent. Customers screenshot texts. Never write anything you would not want shared.

Setting a team texting style

Write a short style note for your team: how you greet ("Hi Maria"), how you sign off ("- Kim"), whether you use emojis, what you never put in a text (prices without context, health details, complaints about colleagues), and the reply target. Two paragraphs is enough, and it keeps a shared number sounding like one business rather than five people.
