• #1 Warm Up: Age your number for 20-30 days with personal activity before bulk campaigns. Establish history.
• #2 Time Gaps: Maintain at least 20 - 30 seconds between each message to prevent filters.
• #3 Message Limit: Limit messages per hour to a range of 60 to 80 (one slot).
• #4 Intervals & Breaks: 60-120s break after 20 messages; 30-60m break after a full slot.
• #5 Mix Contacts: Include family/friends numbers every 10-12 recipients to show genuine activity.

We cannot guarantee zero blocks, but we provide the best settings. WAp only bans spammers accounts if there have been reports from users.

Best Practices & Advice:
• Profile Integrity: Have a profile picture; it reduces manual spam tagging.
• Real Content: Send content person agreed to receive. Random marketing to unknown numbers is high risk.
• Target Limits: Send short messages first when targeting unknown numbers (max 150/day). Only registered customers can receive unlimited messages.
• Points System: Think of it as points: talking & contacts gain points; spam lost points. If you reach zero, account is banned.
• Sim Maturity: Use 20-25 day old WA registrations. New sim numbers are not allowed to send notification messages.

💡 Best Advice: The best way to reduce risk is to include in your message: "If you no longer wish to receive our messages, answer STOP". ✅ This allows users to opt-out instead of reporting you.

⚠️ It means WApp has flagged your account for violating its Terms of Service. WApp’s algorithms detect suspicious activity.

✅ How to Minimize Risk:
✔️ Lower Volume: Start with 10–20 messages per hour.
✔️ Personalize: Add personal greetings (name, location) via our variables features.
✔️ Rotate: Distribute campaigns across multiple numbers.
✔️ Warm Up: Age the number before bulk campaigns.
✔️ Avoid Mass Linking: Mass linking to external sites is detected as spam.

❌ Restriction Facts: Temporary bans last 1–48 hours. WApp doesn’t typically lift permanent bans.

💡 Best Practice: Keep messages conversational, don't rush campaigns, and rotate numbers.

We have implemented many methods to lower the probability of being blocked, but if you annoy the users with too many unwanted messages, they could decide to report you and WAp could block your account. This is a risk that neither we at WhatSender Pro nor the other bulk sending services can completely avoid.

Our software is 100% clean and secure. This is a false-positive detection. Please try downloading the program with Microsoft Edge or Firefox to bypass the Chrome filter.

Business Edition saves customer numbers and names into its database automatically.

Crucial Tip: We recommend using a phone with an EMPTY phonebook as your Bot, so all incoming contacts are correctly categorized in the software database.

If replies are failing and you see this error, please set your WApp Web language to English. This will instantly resolve the API reporting issue.

Images cannot be sent to numbers already saved in the phone book of the Bot device. Maintain an empty phonebook on your smartphone/tablet for maximum image deliverability.
