Notifications from your account are preset to come from firstname.lastname@example.org. If you would like notifications to come from a different sender this can be setup by going to account - notifications:
Scroll down to sender details and enter the email address and name you'd like the notifications to come from:
Please note the email address will need to be verified before any notifications will come from the address, so it's important that you have access to it
Adding custom sender details does run the risk of Looop notifications being rejected by your SMTP. To avoid this issue please check if there is an Anti-Spoofing filter enabled on your SMTP. If there is, please contact email@example.com before enabling sender details and request to enable Domain-based Message Authentication and Reporting & Conformance (DMARC) policy to authenticate the emails.
