The Invitation Text field has the following so I assume it is an introductory/invite email:
"...This is an automated message sent by the WordPress.com subscription service about subscribing and receiving email updates from the following website:..."
As opposed to the confirmation email with a subject line:
"[Subscribe] Confirmed Subscription to Posts on..."
And a body as follows:
Congratulations, you are now subscribed to Barclays Wealth Economics and will receive an email notification when a new post is made.
Woah, slow down with the emails!
You can change the delivery frequency by visiting your subscription dashboard. You can have emails sent when they are published, or aggregated and sent once a day or once a week.
How do I cancel my subscription?
You can cancel your subscription at any time by following one of these options:
· Click on the one click unsubscribe at the bottom of every email
· Visit your subscription dashboard and unsubscribe from there
