What is A/B Testing?
It involves creating two (or more) variations of a marketing message or strategy (A and B), sending them to different, equally sized segments of your target audience, and then comparing their performance based on specific metrics.
Key Elements to A/B Test in BD Phone Marketing:
SMS Copy/Content:
Headline/Opening Line: Does a direct cambodia phone number list benefit or a question perform better?
Call-to-Action (CTA): "Click here" vs. "Shop now" vs. "Reply YES" vs. "Get cashback via bKash."
Message Length: Short and punchy vs. slightly longer (within SMS segment limits).
Language: Pure Bangla vs. English vs. Banglish (mix of Bangla and English).
Tone: Formal vs. informal.
Emoji Usage: Does it improve engagement or appear unprofessional?
Offer Type:
Percentage discount vs. fixed amount discount.
Free shipping vs. a free gift.
Cashback via MFS vs. direct discount.
Offer validity period (e.g., 24 hours vs. 3 days).
Timing and Frequency:
Time of Day: Morning vs. afternoon vs. evening (e.g., for lunch offers, does 11 AM or 12 PM work better?).
Day of Week: Weekday vs. weekend.
Frequency: Does sending one SMS per week lead to better results than two?
Sender ID: Does a branded Sender ID (e.g., "BrandName") perform better than a generic one (e.g., a short code)?
Voice Message Content (for IVR/Voice Broadcasts):
Voice talent (male vs. female, different accents).
Message length and flow.
Key press options.

Segment Audience: Randomly divide a statistically significant portion of your target audience into two (or more) equal groups.
Deploy Campaigns: Send Message A to Group A, Message B to Group B simultaneously.
