7 tips for the best results on WhatsApp bulk messaging

tips on sending whatsapp bulk messages

1. Keep it concise and clear

WhatsApp users value brevity. Ensure your message gets to the point quickly, avoids lengthy paragraphs, and highlights the call-to-action (CTA) prominently.

Example:
"Hi [Name], don’t miss our exclusive deals! Grab them here: [link]"

2. Use a friendly and conversational tone

WhatsApp is an informal channel, so keep your tone light and approachable to connect better with your audience.

Example:
"Hey [Name], guess what? Your favourite [product] is back in stock! Check it out now: [link]"

3. Personalise messages using dynamic fields

Make recipients feel valued by using variables like their name, location, or recent purchase history.

Example:
"Hi [Name], we noticed you enjoyed [product]. Here’s a 20% discount for your next purchase: [link]"

4. Include a strong and clear CTA

Every message should direct the recipient toward an action—be it visiting your site, making a purchase, or contacting you.

Example:
"Limited-time offer! Click here to claim your discount before it’s gone: [link]"

5. Segment your audience for relevance

Customise templates based on customer behaviours, demographics, or preferences to make your message more impactful.

Example:
"Hi [Name]! Looking for new clothes this CNY? Check out our Spring collection here: [link]"

6. Offer value beyond promotions

Messages don’t always need to sell. Provide content that educates, informs, or entertains to keep your audience engaged even when you’re not promoting something.

Example:
"Hello [Name], here’s a quick tip: 3 ways to style your [product]! Learn more: [link]"

7. Use multimedia to enhance your message

Incorporate images, videos, or interactive buttons to make your messages more visually appealing and engaging.

Example:
"Hi [Name], check out our latest arrivals! Tap the button below to shop now."
(Include a visual or button such as "Shop Now")
