On your Email templates page, you can customize who emails are sent from:
With the settings above:
The name of the email sender will be shown as Paddy Mann
The email address of the sender will be app@spidergap.com. Using an @spidergap.com email address is needed to help avoid spam filters and to make it easy to whitelist our email servers.
When a participant clicks to reply to the email, the reply will go to paddy@spidergap.com rather than app@spidergap.com
