best way to send letters?

[Lager]

What is the most secure, fastest and overall best way to send letters via USPS? Certified or Priority with delivery confirmation?

Priority isn't the fastest. It's 2-3 business days. Express is overnight to most areas.

 

First class mail will usually get it there pretty quick - within 5 mail days, usually. However, get delivery confirmation if you want to be sure it got there.

Scan-it then email. That is the fastest
