KS admins have two main options for adding custom text to their test invites.
The default invite email text appears in the 'Invites' page of the KS dashboard.
From this page, a KS admin can overwrite the default text, in the 'Email subject line' field and in the 'Your message' field, on a per invite basis. You have a maximum of 800 characters for your test invite text.
Alternatively, KS admins can write their own custom invite text, which overwrites the KS default text. To do this, go to Settings > Test Invite.
Here, a KS admin can enter their custom invite text and email subject header. You have a maximum of 800 characters for your test invite text. Click 'Save' to register the changes. This custom text will now replace the KS default message on all test invites sent from the account.
The custom invite text appears on the main test invite page.
To revert to the default KS invite text, at any time, a KS admin simply has to delete the custom text from the Settings > Test Invite page of the dashboard.
