SMS usage is tracked monthly and compared to your plan limit on the Billing page.

01

View SMS Usage

Go to Settings > Billing and review the SMS Usage card.

It shows:

  • SMS sent this month
  • Monthly SMS limit
  • Percentage consumed
02

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
03

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:

  1. Open Settings > Billing.
  2. In SMS Usage, click Buy Now.
  3. Complete one-time Stripe checkout.
04

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.
