How to Build a High ROAS Funnel on WhatsApp and Telegram Without Heavy Ad Spending

What is a sales funnel on WhatsApp and Telegram?

A sales funnel on WhatsApp and Telegram is the strategic sequence that transforms a stranger into a follower, the follower into a lead, and the lead into a customer. Unlike traditional funnels based on landing pages and email marketing, the WhatsApp/Telegram funnel takes place within the platform itself — using content, DMs, and automation.

The great advantage is that you can build a funnel with a high ROAS (Return on Ad Spend) without solely relying on paid ads. Organic content, when well-structured and combined with automation, generates results comparable to or better than paid traffic.

The 4 stages of the funnel on WhatsApp and Telegram

1. Top of the funnel — Discovery and reach

The goal here is to appear to as many people as possible. The most effective formats for the top of the funnel are:

  • Reels: greater potential for organic reach. Create content that entertains or educates in under 30 seconds
  • Informative carousels: generate saves and shares, expanding reach
  • Collaborations (collabs): posts in partnership with other profiles broaden the audience

Key metrics: reach, impressions, new followers.

2. Middle of the funnel — Engagement and relationship

Here the follower already knows your profile. The goal is to build trust and authority:

  • Daily Stories: show behind-the-scenes, client results, testimonials
  • Lives: live interaction generates a stronger emotional connection
  • In-depth carousels: valuable content that positions you as a reference

Key metrics: engagement (likes, comments, saves), viewing time.

3. Bottom of the funnel — Conversion

The follower is warmed up and ready to buy. Activate conversion with:

  • Posts with direct CTA: "Comment WANT to receive the link"
  • Stories with link: to product, sales page, or scheduling
  • Automated DM: when the follower interacts, they receive a personalized offer via automation

Key metrics: link clicks, DMs initiated, conversion rate.

4. Post-sale — Retention and referral

Satisfied customers buy again and refer others. Maintain the relationship with:

  • Follow-up messages via automated DM
  • Exclusive content for clients (Stories with Close Friends)
  • Referral programs: reward those who bring in new customers

How to calculate the ROAS of your organic funnel

ROAS measures how much you earn for each real invested. In the case of organic funnels, the "investment" is your time and the automation tool.

Formula: ROAS = Revenue Generated / Total Cost

Practical example: If you earn R$15,000/month from sales coming from WhatsApp/Telegram and invest R$300/month (R$150 in tools + R$150 estimated in time), your ROAS is 50x.

Comparing with paid traffic, where a ROAS of 3-5x is considered good, the organic funnel with automation offers exponentially greater returns for those with an engaged audience.
