1. Verify Your Opt-ins
Never buy lists or send messages to people who haven't explicitly opted in to receive WhatsApp messages from you. High block rates will instantly drop your phone number quality rating and restrict your sending limits.
2. Segment Your Audience
Don't blast your entire database with a generic message. Segment your contacts by their interests, past purchases, or location to ensure the message is highly relevant.
3. Schedule for High Engagement
Timing matters. Avoid sending broadcasts late at night or early in the morning. Use analytics to find when your customers are most active, typically mid-morning or early evening, to maximize open and reply rates.
