Times are difficult if you are in the sales field. I get that.
But sending free stuff won't get you in the door. It will only annoy the admin who has to reach out an contact the sales person who thought it would be a bright idea to send it in the first place. Thereby, fanning the flame of encouragement, only to have it doused by the harsh rejection that is THE ADMIN.
Save your company some money. Don't send unasked for stuff!
