How to Use WhatsApp to Get Clients: Manual Techniques + Automation with KorpDeck

💬 How to Use WhatsApp to Get Clients: A Full Step-by-Step Guide

WhatsApp is not just a messaging app. It’s one of the most powerful and underused platforms for generating real, high-intent clients—especially in B2B environments or when selling digital products and services.

The key? Knowing how to collect and organize phone numbers from the right audiences—and learning how to automate the process without falling into spammy behavior.

🔧 Manual Methods to Get Clients via WhatsApp

While there are automated tools today, many entrepreneurs still rely on manual tactics. Below are some commonly used methods that can still work when used strategically.

1. Collecting Numbers Manually

This is the classic, hands-on approach:

  • Join a public WhatsApp group related to your niche (e.g. “Digital Marketing LATAM”)
  • Open the participant list
  • Manually write down the numbers of real-looking profiles
  • Send each of them a personalized message

Pros:

  • Full control over who you contact
  • Ability to check the profile before messaging

Cons:

  • Extremely slow and unscalable
  • Easy to make copy/paste mistakes

💡 Real Example:
You join a group like “Freelance Designers Mexico.” You manually collect 30 phone numbers and message them offering your web design services. You get 5 replies, and 2 schedule calls.

2. Spamming in WhatsApp Groups

A commonly seen tactic (although discouraged when done carelessly) is dropping sales messages directly in public groups.

  • You send a message like:

    “Hey! I help local businesses appear on Google and get more clients online. DM me if you’re interested. 📈”

  • You post this message in multiple groups across countries or niches.

⚠️ Warning:
Doing this excessively will get you banned or blocked. WhatsApp has strong spam filters and community members may report unsolicited sales messages.

When this works:

  • You write high-quality copy
  • You post sparingly—ideally once per day per group
  • You offer value (free webinar, checklist, tips, etc.)

🌐 Where to Find Niche WhatsApp Groups

Before sending messages or collecting leads, you need to find active groups where your audience is already participating. Below are websites and communities that share updated group links.

Platform Common Niches Found
gruposwhatsapp.net Entrepreneurship, Marketing, Sales, Trading
whatsgrouplink.com Crypto, Tech, Freelancing
linkdegrupos.com Ecommerce, Design, SEO, Coaching
Facebook (search “WhatsApp groups”) Makeup, Fitness, Finance, Business
Telegram (with WhatsApp links) SaaS, Real Estate, Content Creators

💡 Pro Tip:
Use combined keyword + country searches for better results.
Example: “WhatsApp groups ecommerce USA” or “marketing groups Spain WhatsApp”
