Pricing FAQ
What happens if I exceed my email limit?
As you approach your monthly limit, your dashboard shows a usage warning with an upgrade link. If you reach your plan's limit, sending pauses until you upgrade or your quota resets on your next cycle — there are no surprise per-email overage charges. Upgrade before you run out to avoid any interruption.
Can I switch plans anytime?
Yes. Upgrade or downgrade at any time. Changes take effect on your next billing cycle. No long-term contracts.
What do I get on the free plan?
3,000 emails a month (100/day) and one verified sending domain — enough to run a real side project. Higher volume, more domains, higher validation limits, and priority support start on Pro.
Is there a free trial for paid plans?
No — paid plans are charged immediately when you subscribe. The free plan is the trial: 3,000 emails a month and one verified sending domain, with no credit card, for as long as you want. Upgrade only once you've confirmed AISend works for you. You can cancel a paid plan at any time.
