FAQs
How is usage calculated?
You are billed per message sent, per verification completed, per call placed, or per event delivered — depending on the product. There are no monthly minimums or setup fees.
Are there fees for failed deliveries?
No. You are only charged for successfully delivered messages and completed verifications. Failed attempts are retried automatically at no extra cost.
Can I use multiple channels from one account?
Yes. One API key and one account gives you access to SMS, WhatsApp, voice, email, and webhooks. Usage across all channels appears on a single invoice.
Do you offer volume discounts?
Yes. Pricing scales down automatically as your volume grows. For high-volume accounts, contact sales for a custom rate card.
