After spending hours folding letters and sealing them in envelopes, then sorting them into the required postcode categories according to Australia Post guidelines, my husband bumped into Lea, one of the staff at Bendimail. She explained that they do the letter folding, envelope inserting and that they also take care of the Australia Post side of things so that we don't need to do anything other than provide them with the printed material. While they are a bit more expensive than other places in the city, or doing it ourselves, it really is worth it for the time that it saves. My husband will be using Bendimail's services again for future marketing.
