SimpleCertifiedMail.com also supports First-Class Mail™ and Priority Mail.
Sending First-Class Mail in window envelopes is easy to prepare and looks very professional. We provide the plain white window envelopes for a fee. To order envelopes go the Envelopes and Labels tab.
Priority Mail is most often sent using standard 5.5″ x 8.5″ labels that work with your printer and are available at any office supply store.
Clients can also send high volumes of First-Class Mail and Priority Mail through the service using our Mail Services capability, provided that they are able to integrate with our services via RST APIs. Contact Client Services for information.
