Mailing class and postage
What are mailing classes?
As Lob leverages USPS as our mail delivery carrier, the USPS offers a number of mailing services to suit the needs of the business. Leverage different mailing class options based on your time sensitivity, budget, and need for other adjacent services.
First Class Mail
Used to send Lob postcards, self-mailers, letters, and checks
Intended mostly for personal or business correspondence
Invoices, statements, and other confidential mail that include PII/PHI or sensitive data of any kind must be sent via First Class or risk being flagged by USPS and taken out of the mail stream
Businesses have the option of adding on additional services, like Certified Mail
Must weigh 13oz or less; anything over 13oz can be sent as Priority Mail
First Class delivery is given priority over Standard Class Mail, both locally & nationally
Includes forwarding and return services with no additional charge
Domestic mailings typically take 4-6 business days, and international mailings typically take an additional 5-7 business days to be delivered
Standard Class Mail or Marketing Mail
Broadly known as Marketing Mail, or "bulk mail" in the industry
Lob will often refer to it by its previous name, Standard Class Mail, in our product offerings
Used to send Lob postcards, self-mailers, and letters with marketing-related content
Intended more for advertisements and mass communication purposes
Must not contain any sort of sensitive personal information or PII outside the address box
Must weigh 16oz or less, and meet a minimum quantity of 200 pieces or 50lbs of mail
Processed by USPS on a "time available" basis; no delivery time guarantees provided by USPS
Best to avoid with time-sensitive mailings
Least expensive postage mode available on Lob
Mailings typically take 7-21 business days (only available in US)
Standard Class mail cannot be sent internationally
Standard Class mail is not forwarded or returned if undeliverable unless a special endorsement is used; undeliverable mail will be destroyed by USPS
Any mailpiece that contains PII or PHI must be sent as First Class and cannot be sent as Standard Class Mail per USPS regulations. Non-compliance will result in potential removal of your mail batch from the mailstream, customer delays, and/or order cancellation.
Nonprofit Marketing Mail
Saves authorized nonprofit organizations up to 70% of the cost of First Class mail
Only available for domestic mail
Follows the same delivery times as Standard mail
Lob currently does not offer any overnight/express mailing options.
Delivery times are estimates and will vary depending on product and destination. As our primary mail carrier, the USPS also experiences delays from time to time. To see the most up-to-date status of your mailing, check the tracking information of your particular mailing through a GET
request or on your Dashboard.
USPS Marketing Mail eligibility
If you are planning any Marketing Mail campaigns that include the personal information of the recipient, make sure to mail it First Class to avoid USPS rejection which will result in delays for your mail.
Lob cannot currently prevent customers from sending personal information or sensitive data as Standard Class Mail. Consult your Customer Support Manager for further guidance on eligibility.

By building an integrated, distributed network of professional printers, we simplify client print operations and vendor management on behalf of our customers. Qualified commercial printers are thoroughly vetted by our print experts and integrated into our PDN ecosystem, enabling our customers to easily access different mail delivery strategies without the hassle of management.
