Introducing Letters and Small Parcels by Whistl

When you need to send bulk mail, stamps quickly become a problem. Not only are they time-consuming, but mass-mailing your letters and parcels at the standard postage rate becomes incredibly costly.

It can be particularly difficult to calculate stamp postage for multiple items, such as when you want to post an A4 envelope, C5 envelope, poly mailer bags, small parcels and more at the same time.

When stamps become so impractical, you need a better way to send mail in bulk.

Letters and Small Parcels by Whistl is our solution. It brings a fresh approach to sending letters and small parcels in volume. Small parcel shipping and sending envelopes in the post just became easier!

Rather than individually stamping each and every letter, Letters and Small Parcels by Whistl lets you bundle your letters and small parcels into one simple delivery with one label.

There’s no need to sort and organise your letters and parcels. Just hand your box over to the clerk at your nearest drop-off location or to your courier upon collection, and rest assured in the knowledge that your post is on its way.
