Apple Photos does not accept spam messages.

Other people were invited to share the photo album, but the other party did not receive the invitation information. The reason may be that the invitation information was identified as spam or the email address was wrong.

1. The invitation information is identified as spam: it is possible that the invitation information is identified as spam by the other party's mail system, which leads to the entry into the other party's spam box and cannot be seen. At the same time, you can also consider giving gifts in another way, such as inviting sharing through SMS or social networks.

2. E-mail address error: It is possible that the e-mail address was entered incorrectly or did not exist when sending the invitation information, which made it impossible to send it successfully. It is also possible that the invitation information cannot be sent because of unstable network connection or network failure. If these problems occur, you can ask the invitee to confirm whether the email address is correct, check the junk mail folder, or contact the mail service provider for more help.

Shared photo album

Sharing photo albums means creating photo and video albums and easily inviting others to view the shared photo albums. You can create photo albums to view with family, friends, relatives and colleagues. You can create a shared photo album in your mobile phone photo album, enter the name of the photo album you want to share, and then invite your friends to join the photo album. Sharing albums will not occupy the storage space of iCloud, and the creator of sharing albums can invite (share) others to subscribe by using the email address and iMessage number of AppleID.

A shared album is an independent album, similar to a shared folder. Only the content placed in the folder is shared and visible. When creating a new shared photo album, users can invite others to join. If you don't invite others, the album is private. Each shared album can store up to 5000 photos and videos. If it is full, you can choose to build another one.
