Second class postage is included with your bride to be mail and Royal Mail aim to deliver this within 2-3 working days... though we know with the changes to how they process second class mail and how it's scheduled to be delivered over a fortnightly timetable, it's usually much, much slower than this.
 
Postage upgrade options for September's mail:
First class letter (delivery aim of 1-2 days)
Tracked 48 large letter (delivery aim of 2 days, fully tracked from end to end with a link you'll receive by email from Royal Mail)
 
We'll see how this month goes with the upgraded postage and review options moving forward with the potential to permanently upgrade your subscription.
