WhatsApp has introduced text truncation for long messages, changing how marketing and broadcast messages appear in chats. Messages that exceed visible limits are now partially hidden behind a “Read more” option, which directly impacts visibility, engagement, and click-through rates.
For businesses using WhatsApp for promotions, updates, or announcements, this update means one thing: the first few lines matter more than ever. In this guide, we break down what WhatsApp text truncation is, why it was introduced, which messages are affected, and how marketers can adapt without hurting performance.
What is WhatsApp Text Truncation?
Text truncation caps marketing messages at 5 visible lines.
Anything beyond that gets hidden behind a "Read more" button. Users decide whether to expand the message or move on.
It's already live for some users and will reach 100% by mid-October 2024.
The update targets marketing templates, especially the single image + text + CTA button format.
Why WhatsApp Made This Change
Nobody wants to scroll through a wall of text from a brand they didn't ask to hear from. Truncation forces businesses to respect attention.
It also fits into Meta's broader strategy. Earlier this year, they introduced frequency capping to limit how often users see marketing messages. Text truncation is the next step in cleaning up the inbox.
The goal isn't to punish marketers. It's to raise the bar. Messages that work in this format are clearer, sharper, and more likely to drive action.
How Text Truncation Affects Your Campaigns
What Gets Truncated
Marketing messages longer than 5 lines.
Transactional messages, service updates, and OTPs aren't affected.
If you're using the image + text + button template, your message may now look like this:
- First 5 lines visible
- "Read more" button appears
- The rest of the message is hidden until clicked
The Upside
Lower report rates. When users choose to expand a message, intent is higher. They're actively engaging, not passively ignoring.
That means higher open rates, higher click-through rates, and a cleaner sender reputation.
The Challenge
Your first 5 lines now carry the entire load. If they don't hook the reader, the rest doesn't matter.
Best Practices to Adapt to WhatsApp Text Truncation
1. Lead with Value
Your opening line should answer: Why does this matter to me?
Don't bury the offer or the benefit. Put it first.
Before:
"We're excited to announce that our annual sale is back! This year, we've curated exclusive deals across all categories. Check out our new arrivals and enjoy discounts up to 50%."
After:
"50% off new arrivals. Sale ends Sunday."
2. Use the 5th Line as a Hook
If your message needs more space, make line 5 irresistible.
End with a cliffhanger. Make the reader want to know what comes next.
Example:
"Your cart has 3 items. One of them just went on sale. Tap to see which one."
3. Break It Into Sections
If you're sharing multiple pieces of info, use spacing and structure.
Short sections. Clear headers. Digestible chunks.
Example:
Order confirmed.
Delivery: Jan 15
Track: [Link]
4. Write Like You're Texting a Friend
Skip the corporate voice. Be direct. Be human.
WhatsApp is a messaging app, not an email client.
Should Businesses Be Worried About Text Truncation?
No Text truncation isn't a penalty. It's a forcing function.
Businesses that already write tight, engaging messages won't notice a difference. Those relying on long-form persuasion will need to rethink their approach.
The upside? Higher engagement. When users expand a message, they're signalling intent. That's more valuable than a passive scroll.
What Happens to Group Chats?
Text truncation also applies to group chats, where longer messages are common.
For marketers using community or broadcast groups, the rules are the same: keep it short, lead with value, and make the first 5 lines count.
Personal one-on-one chats aren't affected.
When Does This Go Live?
This is live since October 2024.
If your messages aren't truncated yet, they will be soon. Use the time to test and optimise.
