Events use case
Verify registration emails so tickets and reminders actually arrive
Every event runs on email: the ticket, the confirmation, the calendar invite, the day-before reminder, the last-minute room change. If the address a registrant typed is wrong, all of it vanishes and you get a no-show. Verifly checks each registration email in real time and in bulk, catching typos, disposable domains, and undeliverable addresses before your confirmations go out.

A typo’d registration email is a guaranteed no-show
When someone registers for an event, the email address becomes the delivery channel for everything they need to show up: the ticket or QR code, the confirmation with the date and location, the calendar invite, and the reminders that actually drive attendance. If they fat-finger their address on the registration form — gmial.com instead of gmail.com, a dropped letter, the wrong domain entirely — none of that reaches them. They paid or registered, then never got the ticket, and they simply do not come.
Verifly catches the mistake while you can still fix it. A real-time check at checkout returns deliverable, undeliverable, or risky, so you can prompt the registrant to correct an address that will not receive their ticket. That single save is the difference between a filled seat and an empty one.
Reminder deliverability is what fills the room
Attendance is driven far more by the reminder sequence than by the initial signup. The day-before and hour-before nudges are what convert a registration into a body in a seat or a live stream. But those reminders only work if they land, and a registrant list is full of disposable addresses people use to grab a free ticket, plus dead addresses accumulated over past events. Mailing all of them generates bounces that damage your sender reputation and start pushing your reminders into spam for everyone, including the people who genuinely want to attend.
Run your registrant list through the async bulk endpoint before the reminder blast. Verifly removes undeliverable addresses and flags disposable and role inboxes, so your reminders reach real people and your sending domain stays trusted event after event.

Frequently asked questions
How does email verification reduce event no-shows?
Most no-shows tied to email happen because the ticket, confirmation, or reminder never reached the registrant — the address was mistyped or dead. Verifying at registration lets the attendee correct a bad address on the spot, and cleaning the list before reminders means those attendance-driving nudges actually land.
Can I verify the email during ticket checkout?
Yes. A single real-time GET /verify?email= call runs inline at checkout, so you can catch a typo like gmial.com or a missing domain and prompt the registrant to fix it before the ticket is issued to an address that cannot receive it.
How do I stop disposable emails on free-ticket signups?
Verifly flags disposable and throwaway domains explicitly. For free or low-friction events you can require a real address at registration or hold flagged signups for review, rather than issuing tickets to accounts that will never be checked.
Can I clean a large registrant list before a reminder blast?
Yes. Submit the list to the async bulk endpoint, which handles up to 1,000,000 addresses per job, to strip undeliverable and risky addresses before the send so your reminders land and your bounce rate stays low.
Will verifying protect my event sender reputation?
Significantly. Bounces are a strong negative signal to mailbox providers, and event lists accumulate dead addresses across recurring events. Removing them before each send keeps your reminders out of spam for the registrants who genuinely plan to attend.
What does Verifly cost for event organizers?
Pricing is pay-as-you-go from $2 per 1,000 verifications down to $0.60 per 1,000 at the largest pack, with credits that never expire — well suited to the burst-y, per-event nature of registration and reminder sends.
