SMS copywriting: how to write texts people actually answer
Practical rules for writing marketing and sales text messages — length, structure, tone, calls to action, and the phrases that get messages ignored or filtered.
·6 min read
A text arrives in the same place as messages from family and friends, which is both the channel's advantage and its constraint. Anything that reads like a press release gets dismissed instantly.
Good SMS copy is short, specific, and sounds like a person typed it. These rules get you there.
Structure: one message, one job
Every text should do exactly one thing. Name the person, deliver the point, ask for one action. If you find yourself writing the word "also," you have two messages.
Front-load the value. The preview on a lock screen shows roughly the first forty characters, so the reason to care has to appear before your pleasantries do.
- ✓Under 160 characters keeps it to one segment and one glance
- ✓Lead with the benefit, not the greeting
- ✓One call to action, phrased as a question when you want a reply
- ✓Identify your business by name so it is not an unknown sender
Tone: write it the way you would say it
Read the message out loud. If you would not say it to a customer standing in front of you, rewrite it. Contractions, plain words, and normal punctuation all help; exclamation points and all-caps hurt.
Personalization beyond the first name works when it is real — referencing the product they bought or the appointment they booked. Merge fields that simply insert a name into generic copy fool nobody.
What to avoid
Skip the spam signals: all-caps words, multiple exclamation points, public link shorteners, and phrases that make regulated claims about money, credit, or guaranteed results. These get messages filtered before anyone reads them.
Also avoid the false urgency that businesses reach for by default. Subscribers learn fast that every message is a final chance, and then they stop believing any of them.
Key takeaways
- →One message, one action — if you wrote "also," split it.
- →The first forty characters decide whether the rest gets read.
- →Questions get replies; announcements get silence.
- →All-caps, exclamation stacks, and public shorteners invite filtering.

Frequently asked questions
How do you write a good marketing text message?
Identify your business, lead with the specific benefit, keep it under 160 characters, and end with one clear action — ideally a question. Write the way you would speak to the customer in person, and include opt-out instructions on marketing messages.
Should I use emojis in marketing texts?
Sparingly, and only if they fit your brand voice. One well-placed emoji can add warmth; several look like spam. Note that emojis can push a message into a different encoding that shortens the per-segment character limit.
What words should you avoid in text marketing?
Avoid all-caps promotional shouting, stacked exclamation points, and claims about guaranteed income, credit repair, or similar regulated topics. These raise carrier filtering risk regardless of how legitimate your business is.
