Why don't my successful deliveries and failed deliveries for my SMS message add up to 100%?

If you’re seeing a discrepancy in the sum of your successful deliveries and failed deliveries, this may just be the analytics catching up. You can read more about this in our article Review Flow Analytics. If this issue does not resolve after 24 hours, please reach out to support.
