Subscription quota first. Top-ups when you need more.

Every paid plan includes a monthly verification allowance. When that quota runs out, buy prepaid top-up credits instantly instead of changing plans mid-cycle.

Billing FAQ

What counts as a billable check?

Only checks that return a definitive result are charged 1 credit. Cache hits, syntax errors, unknown results, and system errors are always free.

What gets consumed first?

Your included monthly subscription quota is used first. Once that reaches zero, SendGuard automatically deducts from your top-up balance.

Do top-up credits expire?

No. Top-up credits stack and remain available across future billing periods.

How do I change plans?

Use the Stripe billing portal from your dashboard to manage an existing subscription. Top-ups are purchased separately and do not change your plan.
