With myMailHouse, you have three options for sending Certified Mail online


Even in our increasingly digital world, the wet signature return receipt (RR) is still the most widely accepted Certified Mail option in the court of law. If you know you need a wet signature, or you’re unable to find out for sure, the traditional Green Card is your best option for printing, sending, and tracking your important documents. 

Traditional Green Card


When a signature is required on your Certified Mail, take note of whether or not the state or locality pertaining to the document(s) you’re sending allows the use of electronic signature confirmation. If they do, Return Receipt Electronic (RRE) can save you $1.30 per letter, while still providing a legal proof of delivery.
