Pay as you grow

No hard caps. No bill shock.

On any paid plan you’re never cut off mid-campaign. Go past your monthly allowance and the extra email keeps sending — billed as overage at your plan’s per-1,000 rate.

  • Charged in whole 1,000-email blocks — partials carry forward, never rounded up early.
  • Live overage shown in your dashboard and via the usage API — zero surprises.
  • Heads-up emails at 80% and 100% of your allowance.
  • A runaway safety ceiling protects you from a compromised account.
