SMS Usage and Add-on Packs
Monitor monthly SMS limits and purchase additional SMS credits when eligible
SMS usage is tracked monthly and compared to your plan limit on the Billing page.
View SMS Usage
Go to Settings > Billing and review the SMS Usage card.
It shows:
- SMS sent this month
- Monthly SMS limit
- Percentage consumed
Usage Alerts
Billing warns as you approach limit:
- At high usage, you get a low-quota warning
- At 100% usage, SMS quota is exhausted and new surveys fall back to email delivery
Buy an SMS Add-on
Organizations on Pro or Business can purchase one-time SMS add-ons.
Current add-on pack:
- 500 SMS credits
- $10 per pack
To purchase:
- Open Settings > Billing.
- In SMS Usage, click Buy Now.
- Complete one-time Stripe checkout.
When Add-ons Are Not Available
If you are on Starter, add-on purchases are blocked. Upgrade to Pro or Business first.
Usage Planning Tips
- monitor monthly trend early, not only at end-of-cycle
- reserve SMS for high-value or time-sensitive journeys
- keep fallback-to-email behavior in mind for quota protection
If usage spikes unexpectedly, audit recent campaigns and channel selection defaults.
