Pricing FAQ
What happens if I exceed my email limit?
We'll notify you as you approach your limit. You can upgrade at any time, and we won't cut off delivery mid-month — overages are billed at a per-email rate.
Can I switch plans anytime?
Yes. Upgrade or downgrade at any time. Changes take effect on your next billing cycle. No long-term contracts.
Do all plans include AI features?
Free is for testing. Production features like custom domains, higher validation volume, advanced analytics, and priority support start on Pro.
Is there a free trial for paid plans?
Yes! Pro and Business plans include a 7-day free trial. You'll need a credit card to start the trial, but you won't be charged until the trial ends. Cancel anytime during the trial and pay nothing.
