How Often We Update Event Data
Event audiences are constantly changing. New attendees register, exhibitors are confirmed, companies update their information, and some contacts may opt out.
Ongoing refreshes as new registrations and exhibitor information become available.

Event Data Is Not Static
An event database can change significantly as an event approaches and concludes. Attendees may register shortly before the event, exhibiting companies may be added or updated, and contact preferences can change.
That is why VisitorsList does not treat an event list as a one-time static file. Our refresh approach follows the event lifecycle and the availability of new event-related information.
New Registrations
New attendee records may become available as registrations continue.
Exhibitor Updates
Exhibiting companies and related business information can change as the event approaches.
Contact Changes
Opt-out records are removed during applicable refreshes, while newly available records may be added.
How Event Data Is Refreshed at Every Stage
Pre-Event. New registrations and exhibitor updates arrive. Data is refreshed as new information becomes available.
Ongoing Event. The latest available pre-event data is delivered while the event takes place.
Post-Event. The event concludes. The post-event refresh adds new records and removes opt-outs.
45-Day Refresh. New records and updates are added, opt-outs are removed, and the cycle continues every 45 days.
PRE-EVENT
Refreshes Continue as the Event Approaches
For upcoming events, attendee registrations and exhibitor information can continue changing as the event date approaches.
VisitorsList refreshes available event data as new information becomes available.

Purchased Before the Event?
You don't have to wait for the event to conclude to receive available data. You receive the latest available pre-event list at the time of purchase, followed by the applicable post-event update after the event concludes.
DURING THE EVENT
Pre-Event Data First. Post-Event Data After Completion.
If you purchase a list while an event is ongoing, you will receive the latest available pre-event data at the time of purchase.
Once the event concludes and the complete post-event data becomes available, eligible purchases can receive the applicable updated post-event list.
- Purchase During Event
- Latest Available Pre-Event List
- Event Concludes
- Post-Event Data Update
- Updated List Available
Purchased While the Event Is Live?
You don't have to wait for the event to conclude to receive available data. You receive the current pre-event list, followed by the applicable post-event update after the event concludes.
AFTER THE EVENT
Post-Event Data Becomes the New Baseline
After an event concludes, VisitorsList refreshes the event data with the available post-event information.
This post-event refresh incorporates newly available records and removes contacts that have opted out.
The event then moves into the 45-day refresh cycle.

Post-Event Lists Are Refreshed Every 45 Days
Once the event has concluded and the post-event list has been established, the data is refreshed every 45 days.
Each refresh is intended to keep the list aligned with the latest available information.
REMOVED
- Opt-out contacts
- Records no longer eligible for inclusion
- Information identified for removal during the refresh
ADDED
- Newly available records
- Newly identified contacts
- Updated information where available
Every refresh is a data maintenance cycle — not simply a new export of the same list.
What You Receive Depends on When You Purchase
| Purchase Timing | Data Provided | What Happens Next |
|---|---|---|
| Before the Event | Latest available pre-event data | Data continues to be refreshed as new information becomes available. |
| During the Event | Latest available pre-event data | Post-event update follows after the event concludes. |
| After the Event | Latest available post-event data | List enters the 45-day refresh cycle. |
| 45+ Days After Event | Latest available refreshed data | Refresh cycle continues every 45 days. |
Availability and timing of updates depend on when new event and contact information becomes available to VisitorsList.

A Refresh Cycle Built Around Event Timing
Upcoming Events

Post-Event
Scheduled refresh cycleAfter the post-event update, the list is refreshed every 45 days.
What "Updated" Means at VisitorsList
A refresh does not necessarily mean that every record in an event list changes.
Instead, each refresh evaluates the available event and contact information and incorporates relevant changes. Some records may remain unchanged, while others may be added, updated, or removed.
This approach allows the database to evolve with the event rather than artificially replacing records simply because a refresh date has arrived.
Need the Latest Available Event Data?
Whether you are planning outreach before an event, engaging prospects during an event, or following up after it concludes, VisitorsList provides event data according to the stage and availability of the event information.
