How to Track ROI from Bulk SMS Campaigns

Bulk SMS campaigns are fast, affordable, and powerful — but are they actually delivering results for your business?

Whether you're sending promotional offers, reminders, or event invites, tracking ROI (Return on Investment) is critical. It helps you understand what’s working, what isn’t, and how to optimize future SMS marketing efforts.

In this blog, we’ll break down how to accurately track the ROI of your bulk SMS campaigns, along with key metrics, tools, and best practices.

What Does ROI Mean in Bulk SMS Marketing?

In simple terms, ROI = (Revenue Generated – Cost of Campaign) / Cost of Campaign

But for SMS marketing, ROI isn’t just about direct sales. It can include:

• Increased traffic to your website or landing page

• Higher customer engagement

• More bookings or inquiries

• Repeat purchases or upsells

• Improved customer retention

So your ROI depends on your campaign goal — and your ability to measure it accurately.

Steps to Track ROI from Bulk SMS Campaigns

 1. Define Clear Campaign Goals

Start by identifying what success looks like for your campaign:

• Is it driving traffic to a product page?

• Increasing sign-ups for an event?

• Boosting sales of a specific offer?

• Getting feedback or reviews?

Your goal will determine what data to track and how to evaluate performance.

 2. Use Trackable Links (URL Shorteners + UTM Tags)

Never send plain links in SMS messages. Use trackable URLs that help you measure:

• How many people clicked

• Where they came from

• Which campaign they responded to

Use tools like:

• Bit.ly, Rebrandly for short links

• UTM Parameters with Google Analytics for campaign tracking

Example:
https://yourwebsite.com/sale?utm_source=sms&utm_medium=bulk&utm_campaign=diwali_offer

 3. Set Up Google Analytics Goals

Integrate your SMS campaigns with Google Analytics by setting up custom goals such as:

• Purchases or conversions

• Form submissions

• Page views or session duration

• Clicks on CTA buttons

This helps you see exactly how many conversions are driven by your SMS campaigns.

 4. Track Coupon Code Redemptions

If your SMS includes a unique coupon or discount code, you can track:

• How many people used the code

• The total revenue generated

• Conversion rate from recipients to buyers

Tip: Use different codes for different campaigns to compare performance.

 5. Monitor Click-Through Rate (CTR)

Most SMS platforms provide click data. CTR = (Number of Clicks / Messages Delivered) x 100

A high CTR shows that your message was engaging and relevant. If CTR is low, consider optimizing your:

• Message copy

• CTA (Call to Action)

• Offer timing

 6. Measure Conversion Rate

Once users click the link, how many actually take action?

Conversion Rate = (Conversions / Clicks) x 100

This metric tells you how persuasive your landing page or offer was.

 7. Calculate Cost per Conversion

Cost per Conversion = Total SMS Spend / Total Conversions

This is a key metric to compare SMS campaigns with other channels (Google Ads, Email, Social, etc.). The lower the cost per conversion, the higher the efficiency.

 8. Use CRM or POS Integration

If you use a CRM or Point-of-Sale system, integrate it with your bulk SMS platform to track:

• Lead source

• Campaign-driven purchases

• Customer lifecycle value

This gives a clearer view of long-term ROI, especially for repeat customers.

 9. Run A/B Tests for Optimization

Test different versions of:

• Message length

• Offers

• CTA wording

• Sending time

Track ROI across variations to see which version delivers the best return.
