Frequently Asked Questions

▶Can I extract numbers from Eventbrite exports?

Yes. Export your attendee list from Eventbrite as CSV, copy the contents, and paste into NumSwift. It will extract every phone number regardless of the CSV structure. The same approach works with exports from Google Forms, Luma, Meetup, or any other registration tool.

▶How do I handle attendees from different countries?

For international events, NumSwift automatically detects country codes when they are included in the phone number. For numbers without country codes, set a default country. You can process the list multiple times with different country settings if your attendees span several regions.

▶Can I send a bulk SMS to all attendees?

NumSwift opens individual SMS or WhatsApp conversations per number rather than sending bulk messages. This keeps communication personal and avoids spam filter issues. For true bulk SMS, use the extracted numbers with a dedicated SMS platform like Twilio or MessageBird.

▶Is this useful for recurring events?

Very much so. Each time you have a new event, export the registration list, paste it into NumSwift, and extract fresh numbers. Recent extractions are saved locally for quick reference, making it easy to manage communication across a series of events.
