In today's fast-paced world of digital communication, WhatsApp is an overwhelming platform for businesses to communicate with prospects and consumers. With more security measures in place, using high numbers of messages sent from a new number may result in spam detection or even a ban on the account. This is where intelligent practices such as warming up your WhatsApp number are relevant.

If you have an agency that runs marketing campaigns or manage clients' campaigns via a WhatsApp Campaign Manager, you need to begin in the right way. At DigitalPlus, we've witnessed many businesses lose new numbers because they use them incorrectly. To avoid this, this full guide will take you through the steps you need to take to warm up your new WhatsApp numbers effectively.

Why Warming Up a WhatsApp Number Matters

As with email marketing, WhatsApp marketing involves building reputation. Sending 1,000+ messages from a new number on Day 1 activates WhatsApp's spam filters. Their algorithm tracks volume, message recurrence, block rates, and interaction levels.

Warming up assists by slowly building message activity and interaction in a human-like, natural way. This establishes trust with WhatsApp's algorithm and minimizes the likelihood of temporary bans or permanent account blocking.

If you’re using a WhatsApp Campaign Manager, warming up your number will also improve your delivery rate, engagement, and avoid unnecessary disruptions in your campaigns.

Step-by-Step Guide to Warming Up New WhatsApp Numbers

Step 1: Set Up a Professional Profile

Before sending even one message:

Add a high-quality display picture (logo or professional image)

Write a relevant business name and description

Link your website or social handles (if any)

These actions build trust for both WhatsApp and your recipients.

Step 2: Begin with Manual Conversations

Begin genuine, human-like conversations with your familiar contacts:

Send 10–15 one-on-one messages per day during initial days

Do not use templates, copy-paste messages, or media-heavy messages

Prioritize chats with replies (2-way interaction matters)

If your company also provides digital products such as Modern Slide Designs for PPT for Professionals, you can leverage this to share sample templates or respond to queries one on one.

This gentle approach will not only warm the number but also present you as assistive rather than spammy.

Utilize Message Variety and Avoid Automation First

One of the largest aggravations to WhatsApp's spam filters is message repetition and bulk behavior. Avoid:

Sending the same message to many contacts

Employing auto-responders or bulk tools prematurely

Adding unknown users to groups forcefully

Instead:

Diversify your greetings and content

Add questions to elicit responses

Share authentic updates or solicit feedback

Suppose your company, DigitalPlus, assists users with Resume Design for Freshers as well as Professionals as well. You may use this as an opportunity to send brief messages such as:

"Hello! I'm testing this new number for resume tips. Would you like to see a free sample for fresher or professional formats?"

This kind of customized reach-out establishes interaction and warms up your number naturally.

Step 3: Gradual Volume Increase

Here's a conservative sending schedule for warming up:

Day Max Messages/Day Notes

1–3 10–15 Manual chats with familiar contacts

4–7 20–30 Add new but relevant contacts

8–10 50 Begin using basic message templates

11–15 100–150 Light automation permitted

16+ 200+ Resume full-scale campaigns with proven lists

Don't skip steps—even when you're rushed. WhatsApp tracks frequency spikes, and sudden jumps will raise a red flag on your number.

Step 4: Track Feedback and Engagement

Utilize analytics tools (in most bulk sender control panels) to track:

Response rate

Block/report rate

Message delivery status

If you're working with DigitalPlus tools such as Business Sender Pro, make sure you clean inactive or disengaged numbers from your list regularly.

Positive feedback (responses, saved numbers, non-spam status) assists in making your "sender score" better within WhatsApp's internal backend systems. 

Step 5: Incorporate Warmed Numbers Into Your Marketing Stack

After the number is warmed up and stabilized:

Link it with your WhatsApp Campaign Manager tool

Segment audiences through a CRM or contact management system

Connect with your business workflows (e.g., lead follow-up, order support, webinar invitations)

Whether you’re offering resume templates, bulk digital products, or Modern Slide Designs for PPT, automation works better once the trust is built.

Your campaigns will not only reach more people but also see higher engagement and conversion rates.

Common Mistakes That Lead to WhatsApp Number Ban

Avoid these red flags, especially during the warm-up phase:

Sending the same message to over 100 people in one go

Using links, media, or documents in early-stage messages

Ignoring 2-way communication

Causing too many blocks or reports

Attaching unverified or untrusted numbers to third-party tools

Aim to make WhatsApp believe that your usage is natural. Let engagement occur before you scale.

Tools That Can Assist You in Warming Up Numbers Responsibly

These are a couple of tools and strategies that we suggest (and provide) at DigitalPlus:

✅ Account Warmer

An automated tool that simulates real behavior:

Sends staggered messages

Awaits responses

Grads daily volume slowly

Ideal for warming numbers with minimal manual labor.

WhatsApp CRM Tool

???? Digi Bulk Sender Pro

Warming Up Is an Ongoing Process

Even after your number is completely warmed:

Avoid sending over 500–800 messages/day without business verification

Always maintain message quality and value

If you’re scaling, consider rotating multiple warmed-up numbers using tools like Cloud Bulk Sender to distribute load and reduce spam risks.
