Currently, the invitations sent from Bitbucket Cloud have the following sender format:
noreply+someHash@am.atlassian.com.

Example:
noreply+4fe9763d5a7e0b251fb4241dfb5a47d3024ff1149b59bcf9d85ac1ca@am.atlassian.com

However, some customers may interpret this as a SPAM.

This request is for changing that sender to something like no-reply@am.atlassian.com
