What happens at the cap?

Email: inbox creation and outbound sends return 429 with a clear error. Inbound continues to receive but starts dropping past the daily ceiling. SMS: out of plan credits, sends are blocked until you top up or the next billing cycle. Upgrade and it un-caps within seconds.

Do unused SMS credits roll over?

Yes on Pro, Business, and Enterprise. Free trial credits don't roll over. A la carte top-up packs never expire.

Annual or volume discounts?

Yes for Team and above on email, and on SMS Business+. Email sales@getinboxr.app. We don't put the discount math on this page because it's easier to do over a 10-minute call.

Prices in USD. Stripe-managed billing — cancel anytime, prorated refunds. Custom-quoted Enterprise terms include DPA, SOC 2 letter, dedicated CSM.
