We utilize FedEx as our default service of choice; we will also use USPS at department request only. If your agency would like to complete our recommended and complimentary simple Participation Agreement – it’s free – we will add your agency as a named insured on our E&O insurance policy, which would indemnify the agency from any potential liability caused by a lost package. Please call (866) 290-7864 or send us an email to request an agreement.
