Posted: Sat May 24, 2025 3:45 am
Running a phone number list campaign—whether via SMS, voice calls, or messaging apps—is only as effective as the results it delivers. To understand whether your efforts are paying off, it’s essential to track the right performance metrics. Measuring success helps optimize future campaigns, maximize return on investment, and improve engagement with your target audience. Here’s a breakdown of the key ways to measure the success of your phone number list campaigns.
1. Delivery Rate
The delivery rate indicates how many of your messages successfully reached recipients’ phones. A low delivery rate may signal:
Invalid or outdated phone numbers
Carrier blocks
Technical issues with your service provider
Formula:
(Delivered Messages ÷ Total Messages Sent) × 100
Goal: Aim for a delivery rate of 95% or higher, especially when working with verified lists.
2. Open Rate (for SMS campaigns)
Open rates tell you how many people actually opened or viewed your message. SMS campaigns typically see very high open rates—often over 90%—due to the immediacy and visibility of text messaging.
While not all platforms offer precise open tracking, some advanced tools or shortened link analytics can provide good estimates.
3. Click-Through Rate (CTR)
If your message contains a link (such as to a landing page, coupon, or product), the click-through rate tells you how many recipients engaged with the call to action.
Formula:
(Clicks ÷ Delivered Messages) × 100
CTR shows how compelling and relevant your message is. High CTRs usually reflect strong targeting and effective copywriting.

Ultimately, success is measured by how many recipients take your desired action—such as making a purchase, booking an appointment, or signing up for a service.

Custom landing pages
Coupon codes unique to each campaign
