What types of mail can you send with LetterStream? We hear this question a lot from teams who just want mail to be simple and dependable.

LetterStream is built for businesses that need to send mail without slowing everything else down. Instead of juggling printers, spreadsheets, and Post Office trips, teams can manage their mail in one place and trust that it’s handled accurately and reliably.

Below is a clear look at the types of mail and mail products you can send, along with guidance on when each option makes sense.

USPS First-Class Mail

USPS First-Class Mail is the most common choice for everyday business communication. It works well when tracking or proof of receipt isn’t necessary, and you simply need your mail sent through the postal system without extra steps.

Many customers and businesses use First-Class Mail for routine letters because it’s straightforward and predictable.

First-Class Mail is often used for:

  • General business letters
  • Invoices and billing statements
  • Customer notices and updates

USPS Certified Mail

USPS Certified Mail is designed for situations where confirmation matters. It includes tracking and can include proof of receipt through Electronic Return Receipt (ERR), which helps support documentation and recordkeeping.

This option is commonly used when accountability is required, but the process still needs to stay efficient.

Certified Mail is often used for:

  • Legal and compliance notices
  • Important business communications
  • Mail that requires tracking

FedEx 2Day Mail

FedEx 2Day Mail is the fastest sending option available through LetterStream. It includes tracking and can include proof of receipt through an electronic signature.

This option is typically used when timing is critical, and documents need to move quickly without sacrificing accuracy. It’s also the most reliable and offers the highest level of security.

FedEx 2Day Mail is typically used for:

  • Time-sensitive business documents
  • High-priority communications
  • The most secure way to send mail

Postcard Mail

Postcard Mail is a good fit when your message is short and doesn’t need an envelope. It’s also good when design is an important element in your messaging. LetterStream offers postcards in two sizes, making them useful for reminders, announcements, and simple outreach.

Postcard options

  • Pro Postcard: Full-Color 5.5” x 8.5”
  • Express Postcard: 4.5” x 5.5”

Because the message is visible right away, postcards are often chosen when clarity and visibility matter most.

Flats Mail Options

Flats Mail is used for larger mail pieces that don’t fit into a standard envelope. This option works well when your materials need more space, such as detailed notices, HOA Annual Meeting notices, or expanded communications.

Businesses often use Flats Mail when the content is too large for standard letter formats but still needs to be sent consistently and accurately.

Payment Coupons

Payment coupons are typically used for recurring payments and structured billing programs. These mailings help customers submit payments by mail using preformatted coupons.

They are commonly paired with:

  • Membership programs
  • Subscription services
  • Ongoing billing cycles

Payment coupons are sent using First-Class Mail and help keep recurring communications organized.

Statements & Invoices

Statements and invoices are some of the most commonly sent types of business mail. LetterStream supports these mailings when accuracy, consistency, and timing matter.

Businesses often rely on this option for billing communications that need to go out regularly without manual effort.

Ballot Proxy Mail

Ballot Proxy mail is used for official voting materials, such as HOA ballots, association elections, and proxy voting documents.

These mailings often require careful handling, consistency, and clear presentation. LetterStream helps organizations manage this type of mail without adding unnecessary complexity.

Mail Products You Can Send with LetterStream
