What is Whistl?
Whistl is an add on which we can arrange for you - it will allow you to physically send letters via the Postbag to save you from the administrative and physical actions of posting letters yourselves.
For example, if you have letters in your postbag, you would normally "authorise" them - but you would still need to go into your postbag, print the letters, put them in a stamped envelope and post the item. Now, you can "post by Whistl" so that the posting can be arranged for you, saving you money on stamps and time from the posting process.
You still send letters as before via your postbag.
When you authorise your letters, you can either bulk select or choose the letter individually.
To send via Whistl, just select "Post By Whistl" and select your desired format and postage.
