It can happen that customers contact you when they cannot find certain emails in their mailbox. These include, for example:
- Reminder and confirmation emails
- Forgotten password emails
- Newsletters
However, it can also be Belbo system emails that you as the owner of a Belbo calendar expect to find but cannot locate. These include, for example:
If you are certain that the corresponding email was sent, for example if it can be found in the "Messages" tab of the customer record, it is likely due to your customer's mailbox settings that it cannot be found there.
Automatic mailbox rules (e.g. Google Mail)
Some email services, especially Google Mail, offer users the ability to pre-sort emails so that not all messages land in the normal email inbox. Messages that Google classifies as desired advertising or notifications can be retrieved somewhat hidden. Please ask the customer to check these mailboxes and, if necessary, change the automatically created rule:

Custom mailbox rules
Custom rules for specific senders can be created with all email services. If it was previously specified that messages from your company should always be marked as "Read" and archived, other messages may also be affected.
Rejected messages and spam
Your customers have the option to mark your newsletters or reminder messages as spam if they no longer wish to receive them. In this case, future messages will also be sorted into the spam folder.
Some email service providers can also make this decision on their own. There are international guidelines that email service providers use to determine which senders are classified as spam senders. The service we use for sending emails has an excellent reputation and is very rarely marked as spam. Nevertheless, it can happen occasionally.
We ask for your understanding that we have no control over this. Your customer can mark the sender as safe in order to receive future messages again.
