Setting email reminders

Last updated: August 28, 2025

Reminders

The Email Reminder feature allows you to set up automated email reminders that will be sent to registered users relative to an event’s publishing date. Reminders can be scheduled for both before and after the publishing date.

Setting Up Reminders

Reminders are configured with a time offset in minutes from the publishing date

  • Negative offset values (–60) schedule the reminder before the publishing date
  • Positive offset values (60) schedule the reminder after the publishing date You can add reminders by enabling RegistrationEmail settingsEmail reminders, and clicking Add reminder email before the event or Add follow-up email after the event.

After clicking either of the buttons above, you will see a form like this:

Wherever you use :EVT_NAME, it will be replaced with the event’s name.

You can also preview the email with Preview reminder email which opens only a preview of the email that will be sent. Final email may differ from this preview as email clients render the email differently.

Smart Anti-Spam Protection

To prevent users from receiving reminders too soon after registration, the system implements smart timing logic:

Minimum Time Before Reminder

The system calculates a minimum required time between user registration and when they can receive a reminder. This is determined by:

  1. Taking the absolute value of the reminder’s offset and doubling it
  • Example: For a 1-hour pre-event reminder (–60 minutes), the minimum time would be 2 hours
  • Example: For a 3-hour post-event reminder (180 minutes), the minimum time would be 6 hours
  1. The system enforces a minimum threshold of 2 hours, even for small offsets
  • Example: For a 30-minute pre-event reminder (–30 minutes), the minimum time would still be 2 hours
  1. The minimum time is capped at 24 hours for large offsets
  • Example: For a 24-hour pre-event reminder (–1440 minutes), the minimum time would be capped at 24 hours instead of 48 hours

Examples

  1. Short Pre-Event Reminder
  • Reminder set for 30 minutes before event
  • User registers 1 hour before event
  • Result: No reminder sent (less than 2-hour minimum)
  1. Standard Pre-Event Reminder
  • Reminder set for 2 hours before event (–120 minutes)
  • User registers 5 hours before event
  • Result: Reminder will be sent (exceeds 4-hour minimum)
  1. Long Post-Event Reminder
  • Reminder set for 12 hours after event (720 minutes)
  • User registers 20 hours before the reminder time
  • Result: Reminder will be sent (exceeds 24-hour cap)

Best Practices

  1. For important announcements close to the event time (less than 2 hours), consider using immediate notifications instead of reminders
  2. When setting up long-term reminders (> 12 hours), remember that the anti-spam protection is capped at 24 hours
  3. Consider the user experience when setting multiple reminders - ensure they are spaced appropriately to avoid overwhelming users

FAQ

I didn’t get an email after registration

You might just have registered or the email sending might be capped out because of other time-sensitive reasons. Please see Smart Anti-Spam Protection section for details and probable reasons.

Can I use my own email address instead of no-reply@videosync.fi for registration confirmations?

Yes, you can customize the organizer email address for registration confirmations. Changing from the default no-reply@videosync.fi to your own email address does not affect spam risk or email deliverability.

However, there are important considerations when using a custom email address:

  1. Functional email requirement: The email address must be active and functioning. Using a non-existent email address will cause viewers to receive bounce messages.

  2. RSVP responses: Some email clients (particularly Gmail) send RSVP responses directly to the organizer email address. The owner of the custom email will receive these responses.

  3. Contact management: The email address should belong to someone who can handle participant queries, as attendees may send questions, cancellation requests, or other inquiries to this address.
