EventHub uses email addresses to identify participants. To prevent errors and communication issues with participants, make sure to use valid addresses. If you are experiencing issues with users not receiving invitation emails, please confirm the following possible reasons:
Case I：Invalid email address, typos
The user may have registered with an invalid or mistyped email address.
Case II：Spam inbox
The email may have been sent to the user's spam inbox.
Case III：Email rejected by server
EventHub emails may have been blocked by the user's email server. Users can follow the below steps to make sure emails are sent to their main inbox:
① Login to your Gmail account
② Click Settings > See All Settings
③ Select Filters and Blocked Addresses, and create a new filter
④ In the 'From' section, type 'eventhub.jp' and select 'Create filter'
⑤ Check off 'Never send it to spam' and select 'Create filter' once again
<tips>Spam inbox errors and domain blocks must be edited by the user. To prevent issues, we recommend requesting users to:
・Check their spam inboxes
・Check whether eventhub.jp is blocked by their email server</tips>
If the user does not receive the email even after looking into the above issues and resending the invitation email, we will be unable to identify the cause or provide a solution. If you continue to experience issues, please ask the user to change or register a new email address and resend the invitation email.
