Why Businesses Use CTWA Retargeting

Every WhatsApp conversation your business has represents a potential opportunity. Even if a customer does not immediately make a purchase, their interaction still indicates interest.

Many businesses try to reconnect with these leads by sending WhatsApp marketing template broadcasts. While this can work in some cases, it often becomes expensive and inefficient as the lead database grows.

CTWA Retargeting offers a smarter alternative. Instead of sending paid messages to every contact, you show targeted ads only to users who have already interacted with your business on WhatsApp, bringing them back to the same conversation.

To understand the difference, let us compare both approaches.

Broadcast Messaging vs CTWA Retargeting

Factor	WhatsApp Marketing Broadcast	CTWA Retargeting
Communication Method	Direct marketing template message	Facebook/Instagram ads
Cost Structure	Pay per message sent	Pay for ad reach/engagement
Typical Cost	₹0.99 per marketing template	Flexible ad budget
Cost for 1,000 Leads	₹990	₹300 – ₹600
Cost for 10,000 Leads	₹9,900	₹2,000 – ₹4,000
Response Rate	1% – 5%	5% – 15%
Conversation Continuity	User must reopen chat manually	Clicking the ad reopens the same WhatsApp chat

This shows that broadcast messaging reaches everyone, while CTWA Retargeting focuses on users more likely to respond.

Scenario 1: Sending WhatsApp Marketing Template Broadcasts

Marketing templates are paid messages, so you are charged for every message sent.

For example:

1,000 leads × ₹0.99 = ₹990

10,000 leads × ₹0.99 = ₹9,900

However, most broadcast campaigns see only 1%–5% response rates.

So if you message 10,000 leads, only around 100–500 users may respond.

Additional Challenges with Broadcast Campaigns

Frequency Capping

WhatsApp applies frequency limits on marketing messages.

If you send a broadcast to 10,000 contacts, typically only 60–70% of messages are delivered initially.

That means:

• 6,000–7,000 messages delivered

• 3,000–4,000 messages delivery failed

Businesses often have to retry broadcasts multiple times to reach the remaining users.

---

Risk of Number Restrictions

Sending marketing messages to large lists can also increase the risk of WhatsApp number restrictions.

If recipients:

• Mark messages as spam

• Block the number

• Report the business

WhatsApp may reduce messaging limits or temporarily restrict the number.

This risk increases when messaging:

• Older databases

• Contacts who never interacted recently

• Third-party or unknown data sources

---

Large Databases Become Expensive

Many businesses store large contact databases over time.

Example:

100,000 contacts × ₹0.99 = ₹99,000 per broadcast campaign

In addition to the cost, businesses may also face:

• frequency limits

• spam complaints

• low engagement

---

Scenario 2: Using CTWA Retargeting

CTWA Retargeting works differently.

Instead of sending messages directly, you run Facebook and Instagram ads shown only to users who previously interacted with your business on WhatsApp.

When users click the ad, the same WhatsApp conversation opens again.

For example:

A campaign with a budget of ₹2,000 – ₹4,000 can reach 10,000 previously engaged users.

Because these users already know your business, engagement rates are usually higher than broadcast campaigns.

---

Why CTWA Retargeting Works Better

Familiarity Users recognize your brand from the earlier conversation.

Relevance Ads target people who already showed interest.

Better Timing Users see the reminder while browsing Facebook or Instagram.

Conversation Continuity The WhatsApp chat reopens instantly when they click the ad.

---

Key Takeaway

Sending broadcast messages means paying for every message, even if most users do not respond.

Businesses may also face:

• frequency capping

• delivery limitations

• spam reports

• risk of number restrictions

• high costs for large databases

CTWA Retargeting helps businesses re-engage interested users through targeted ads, bringing them back into the conversation in a more natural and cost-efficient way.
