Credits roll over while subscribed · cancel any time · plan credits are spent first
A plan tops your credits up every cycle and whatever you don’t use rolls over to the next one, for as long as the subscription runs. Cancel and the rolled-over balance goes with it. If you would rather own your credits outright, buy a pack below instead: those are valid for 12 months. You can do both: a plan that runs dry mid-cycle can be topped up with a pack, and plan credits are always spent first, so the ones you bought outright stay yours. Where a plan states a daily limit, that is the most it will spend in one day whichever way you spend it (the API, the dashboard or a bulk job all count against it), and the day resets at midnight UTC.
Prices are in USD. GST applies only to INR billing, and every payment comes with an invoice.
Work Out Your Cost
Covered by the 10,000 credits you start with
One credit verifies one address; a full domain audit costs 1. Every new account gets 10,000, so a list this size costs nothing to clean.

Should I Subscribe or Buy Credits?
Subscribe if you verify on a regular rhythm: the plan tops you up every cycle and whatever you do not use rolls into the next one, so a quiet month is not wasted. Buy a pack instead if your work comes in bursts, because those credits are yours outright and valid for 12 months. You are on one or the other at a time, and while a subscription is running credit packs are unavailable.
What Happens to My Credits if I Cancel?
The subscription keeps running until the period you have paid for ends, and the credits it granted stay spendable until then. When it ends, the rolled-over plan balance is removed. Credits you bought as a pack are untouched: plan credits are always spent first, so cancelling never takes something you paid for separately.
How Accurate Is a Verification?
Each address is checked against the receiving mail server in real time rather than looked up in a cached list, so the answer reflects the mailbox as it exists right now. Where a server refuses to give a definitive answer, we return unknown instead of guessing a verdict.
Will Verifying Hurt My Sender Reputation?
No. Verification runs from our own sending infrastructure and never delivers a message to the address being checked, so nothing lands in the recipient's inbox and nothing is attributed to your domain.
What Happens to Credits on a Bulk Job?
Credits are held when the job starts and settled when it finishes, so you keep the ones you did not use. Rows that were never attempted, because you cancelled the job or it stopped early, are refunded. So are rows that finished as unknown: you are only charged for addresses that reached a real verdict.
What Does a Catch-All Result Mean in Practice?
The domain accepts mail for every address, so a successful SMTP handshake does not prove the mailbox exists. We label it honestly and attach a risk score rather than reporting it as valid, and you decide whether to keep it.
Can I Verify Inside My Own Product?
Yes. Create an API key in the dashboard and call the REST API at signup, on form submit, or from your CRM. Bulk jobs stream live progress over SSE so you can show a progress bar without polling.
How Is My Uploaded List Handled?
Your list is processed to produce your results and nothing else. We do not sell it, do not use it to send marketing, and do not share it with other customers. It is handled by the service providers who run InboxValid, under contracts that require them to protect it. Jobs and their results are kept so you can reach your history, and can be deleted on request; the privacy policy has the detail.
