Every ticket needs an inbox that exists.
Registration lists collect typos fast. Verify the list before tickets and badges go out, so confirmations reach real inboxes instead of bouncing.
Registration forms collect typos under pressure.
People register for events on their phones, in a hurry, often on a conference wifi — and a slip of the thumb becomes an attendee who never gets the ticket. They don't know it failed. They just show up with nothing to scan, at the desk, at nine in the morning.
Verifying the list before tickets go out finds those addresses while there's still time to follow up — and where the pipeline spots a likely typo, it suggests the fix, so your team can rescue the registration instead of dropping it.
How you do it
Export registrations
Download the attendee list from your ticketing platform as a CSV.
Upload and verify
A few thousand registrations run in minutes; duplicates and blank rows are skipped free.
Rescue the typos
Flagged rows carry the reason and — where detected — the suggested correction, so the desk list gets shorter, not longer.
Send tickets to the clean list
Export deliverable-only rows for the ticket send; follow up with the rest by other means.
Product UI shown with sample data.
Every answer is explained — and nobody gets emailed.
Four honest outcomes
deliverable, risky, undeliverable — or an honest unknown when a mailbox can't be confirmed, instead of a confident guess.
A reason for every row
A 0–100 score plus a machine-readable reason (no_mx, mailbox_not_found, disposable_domain…) you can act on and show your team.
No email is ever sent
The mailbox probe talks to the receiving server but always stops before any message — the people on your list never see anything.
What 5,000 registrations costs
One credit checks one address. Pay once — credits never expire, and there's no subscription required. The full rate schedule is on the pricing page.
Frequently asked questions
Credits never expire, so what you buy for the spring event is still there in autumn. There's no subscription required — buy once, spend as events come.
Where the pipeline spots a likely typo it suggests the correction, and the export carries the reason for every flagged row — so your team can follow up with attendees who mistyped instead of silently dropping them.
No. The mailbox check never sends an email — attendees see nothing until you send the actual tickets.
