When building a campaign we suggest you send an email with the link to the resource or pathway at the same time you share the resource or pathway with the users.
The reason for this is because:
you can totally customise the email, pick your picture and the text
the email will come from your sender details (as found in account > notifications)
When sharing a pathway or resource via campaign:
the user is enrolled in it, so instantly feeds into the analytics
they user gets access to the resource/pathway
the resource/pathway pins to the homepage
If you turn on the send share email instead of building your own:
the email looks more generic and won't be as engaging
the email comes from the user who created the campaign rather than from the main sender you have chosen
