Product Update: Send Postcards and Letters with USPS Standard Mail

Today we are happy to announce a new Mail Class option for our postcard and letter offerings: USPS Standard Mail! By default today, we send all postcards and letters as USPS First Class Mail, which is a faster and more predictable mail delivery option offered by the USPS. For businesses that can benefit from it, Lob is now offering USPS Standard Mail as a new delivery option for all of our customers!

When should I use Standard Mail?

Standard Mail is a cheaper delivery option, but is less predictable and takes longer to deliver than First Class. First Class Mail is typically delivered between 4-6 business days from your API request to Lob, while Standard Mail can take anywhere between 7 to 21 business days, as the USPS does not provide delivery time guarantees for Standard Mail.

If you have a use case that is time sensitive, we do not recommend using Standard Mail. However, if you don’t mind the longer and less predictable delivery times, Standard Mail is a great option to save money. For certain marketing or non-time sensitive operational use cases, this may be a great option for your business to consider.

Note: Standard Mail can not be sent outside of the US.
