How to Avoid Getting Banned on WhatsApp While Using Trembi Campaigns

If you're using Trembi Campaigns or Trembi Sales AI to send WhatsApp broadcasts or automate communication, it's crucial to stay compliant with WhatsApp’s guidelines to avoid getting banned. WhatsApp has strict systems in place to detect spammy behavior, and once your number is flagged, it can be hard or impossible to recover.

In this article, we’ll show you how to keep your WhatsApp number safe, maintain a high delivery rate, and protect your sender reputation. Let’s start with a quick summary of the essentials, and then dig into the details.



Part 1: The Essentials

1. Warm Up New Numbers

New WhatsApp numbers are highly sensitive and often flagged quickly if used for mass messaging without any history.

What to do:

  • Use the number like a regular user first—send and receive chats, media, voice notes.

  • Wait at least 24 hours before scanning the QR code in Trembi Campaigns.

  • Chat with real people and simulate normal use for a few days.

2. Minimize Spam Complaints

The most common reason for getting banned is being reported for spam.

Tips to reduce complaints:

  • Let users contact you first. Add a “Chat with us on WhatsApp” button to your website or ads.

  • Start with a question in your first message to encourage replies.

  • Include a STOP option: Add a line like “Reply STOP to unsubscribe” to give users control.

  • Personalize your messages with names and relevant content.

  • Avoid sounding robotic or generic—remember, recipients see a "Block" button first thing.

3. Avoid Sudden Mass Activity

Don’t start blasting hundreds of messages on day one.

Suggested pace for new numbers:

  • Max 2 messages per minute

  • No more than 6 hours/day

  • Max 3 consecutive days of activity before taking a break

Gradually scale up your sending over time.

4. Aim for a Healthy Response Rate

If you send 100 messages and get only 1 reply, WhatsApp sees that as spam behavior.

Ideal benchmark: Get at least 30 replies for every 100 messages.

Encourage interaction. The more real conversations you generate, the safer your number is.



Part 2: In-Depth Tips to Stay Safe

Understand WhatsApp’s Behavior Algorithms

WhatsApp uses AI to detect patterns that look unnatural. If your activity doesn’t resemble how real people use WhatsApp, you're at risk.

Avoid these behaviors:

  • Sending identical messages to many people

  • Messaging strangers who don’t know you

  • Sending links right away

  • Messaging at predictable intervals (e.g., every 10 seconds)

  • Not receiving any replies

Best Practices When Starting Conversations

It’s safer when the customer messages you first. But when you have to initiate:

  • Use Trembi’s Click-to-Chat link with prefilled text (e.g. “Hi! I’d like to know more.”)

  • Add the link to your ads, site, or email signature

Build a Loyal Audience

Stick to contacts who:

  • Know your brand

  • Have interacted with you before

  • Are more likely to respond positively

Ask users to save your WhatsApp number in their contacts—this boosts your credibility.


Avoid Spammy Content

Always send useful, relevant, and personalized messages. People should feel glad to hear from you not annoyed.

Use tools like ChatGPT to vary your content and make it sound human.


Be Careful with Links

Never drop a link in your first message unless it’s expected. When you do send links:

  • Use HTTPS

  • Consider shortening links with tools like Bitly or TinyURL

🧠 Act Like a Human

Add subtle touches that show your number is real:

  • Respond to chats

  • Use emojis

  • Show “typing...” or “audio recording” status (Trembi supports this)

Avoid messaging people who don’t engage—pause communication instead of spamming them repeatedly.


Technical Tips for Trembi Users

Number Warm-Up

Before using a number for mass campaigns:

  • Chat manually for a few days

  • Include different message types (text, images, audio)

  • Avoid scanning the QR code on the same day you register the number

Message Limits

Stick to these rules:

  • Send 6–12 messages per minute max

  • Randomize timing—don’t send at exact intervals

  • Take breaks between batches

If you need higher volumes, consider rotating multiple WhatsApp numbers across different Trembi Campaigns.

Optimize Your Profile

Add:

  • A clear profile photo (e.g. your logo)

  • A helpful business description

This increases trust and reduces the chances of being flagged as spam.

Stay Local

Target users from the same region as your phone number whenever possible. For example, a Ugandan number messaging only people in Brazil looks suspicious.


If You Get Blocked

If WhatsApp bans your number:

  • Try logging in and follow the unblocking process

  • If you're permanently banned, register a new number

  • Make sure to warm it up properly before linking it to Trembi

Unfortunately, Trembi (or any platform) cannot unblock a banned number—this is entirely up to WhatsApp’s internal system.

Final Thoughts

Using Trembi Campaigns to connect with your audience on WhatsApp can be powerful but only if you do it right. Treat your number like a brand asset. Avoid spammy behavior, build trust with your audience, and scale responsibly.

By following the tips above, you’ll reduce the risk of being banned and maximize the impact of your WhatsApp campaigns.
