Common Issues and Solutions
Most issues fall into a few categories: invitations, registrations, check-in, or technical glitches. Here’s how to resolve them.
Invitation Issues
🔴 Critical: You’ve reached your invitation limit
- Wait for responses to receive refunded credits (one credit back per response)
- Use your shareable event link in external channels
- Focus quality over quantity with remaining invitations
See invitations guide for strategies.
🟡 Important: Your invitations have low response rates
- Verify event description clearly communicates value
- Review invitation message for clarity and appeal
- Test different send times
- Personalize invitations to increase relevance
🟢 Minor: An invitee can’t find their invitation
- Verify email address matches their Sero account
- Ask them to check spam/promotions folders
- Resend invitation if necessary
- Provide direct event link as alternative
Corporate firewalls or email filters can affect deliverability.
