SMS marketing: why it works and how to write it right
SMS has a 98% open rate — higher than email, social media, or any other marketing channel. But the rules are different: you have 160 characters, no formatting, and you're interrupting someone's day. Make every word earn its place.
Lead with the offer
Don't build up to it. Open with the core value: '30% OFF today only' beats 'Hey, we have something special for you'.
Create real urgency
Deadlines work. 'Ends midnight tonight' outperforms 'limited time offer'. Be specific about the expiry.
One CTA only
Don't ask them to visit the site AND call AND reply. Pick one action and make it frictionless.
Identify yourself
Always include your business name in the first 15 characters. 'SwiftCopy: ...' builds trust and context.
