Common questions
Can I switch plans later? +
Yes — any time. Upgrades are prorated and take effect immediately. Downgrades apply at the end of your current billing period, so you keep what you paid for.
What counts as a monitored domain? +
A sending domain (e.g. yourcompany.com) that we re-test automatically on a schedule. Each monitor sends one probe email per run and grades it against SPF, DKIM, DMARC, blacklists, and the other 10+ checks. Pro includes 5 monitors; Agency includes 25.
Can I cancel anytime? +
One click in your billing portal. No "contact us to cancel," no retention gauntlet. Your subscription stops renewing and you keep access until the end of your billing period.
Do you offer refunds? +
Yes — 30-day money-back guarantee on Pro and Agency. If InboxGrade didn't do what you expected, email billing@inboxgrade.io within 30 days of your first charge and we'll refund the full amount, no questions asked.
Need production email delivery that passes every grade?
We built InboxGrade on Postmark because their delivery is boring in the best way — no shared-pool reputation gambles, no "hopefully it delivers" days. Highly recommended if you need transactional mail that actually arrives.
