The Psychology Behind SMS Success

SMS works because it's:

Personal: Delivered directly to their phone

Urgent: Creates FOMO and immediacy

Trustworthy: They know your number

Interruptive: It demands attention

But this power comes with responsibility. Abuse it and you'll get unsubscribed instantly.

The Framework: AIDA for SMS

Your first line makes or break the message.

❌ "We have a sale"

Interest

Hook them in the first 160 characters.

Desire

Make them want what you're offering.

Action

Tell them exactly what to do and how to do it.
