Answer Button and change background
Yve can use two types of buttons in emails. With 'Reply Button', the participant can directly access the event website without having to log in. With 'commitment / cancellation button' he replies directly after a confirmation. You can change the text and color of the email buttons here.

 

The answer button contains the ID of the invitation and a 20-digit security token specific to the contact. You can re-generate the token for each contact under 'Contact Details -> Password -> Login Token generate new' if this is desired for security reasons. Old invitations for this contact will then no longer work.
 
Via Email Background & Colors you can change the defaults for background color, body color, font color, font, font size.

 

With 'Event-> Emails-> Email type names' you can change the name of the workflow emails and PDF attachments shown in yve.
