It uses raw PDF pages with no inserted address page and supports up to 99 single-sided or 198 double-sided pages. Signature confirmation is available for an extra $4.20 on the customer-facing price. ## Certified mail cost Certified Mail is available with First Class only. Select Certified Mail in the calculator to see the added cost for tracking, then add electronic return receipt if you need signature evidence. ## Bulk pricing and high page counts Each estimate is for a single letter. If you need bulk pricing or higher page counts, contact support so we can tailor a workflow. ## Related pricing resources - See full [pricing details](/pricing). - Review [delivery times](/delivery-times). ## Ready to send it?
