When timing matters, waiting for mail to go out isn’t an option. Whether you’re handling billing, compliance, or legal communication, knowing exactly how fast your mail goes out the door can make all the difference.
So how fast is fast at LetterStream? We guarantee a 2-business-day mailout, and many jobs go out even sooner—often by the next business day. Below, we’ll break down what that guarantee means, how The Stream works behind the scenes, and which mail types you can send.
What “Fast” Mail Means at LetterStream
LetterStream measures speed by how quickly your mail enters the mailstream after you submit it. Once your files are uploaded, The Stream moves them through print, preparation, and handoff without manual steps slowing things down.
Every job runs through StreamLogic, our proven methodology for managing mail at scale. Because workflows are automated, mail moves consistently and predictably from start to finish.
The result is a reliable 2-business-day mailout—without added coordination or extra effort on your end.
Many Mail Jobs Go Out Even Faster
While two business days is the guarantee, many jobs are sent sooner. In many cases, 94% of mail goes out by the next business day.
This happens because The Stream is designed to keep work flowing smoothly from submission to mailout. There’s no waiting on equipment, supplies, or staff availability. Mail enters production as soon as it clears basic checks.
For teams handling time-sensitive communication, that consistency makes planning far easier.
Expedited and Rush Mail Processing Options
Sometimes, even faster matters. When timing is critical, LetterStream offers upgraded processing options.
Expedite Processing
Guaranteed mailout by the next business day.
Additional fee: 10% of the total cost + $1.99.
Rush Processing
Guaranteed same-day mailout when submitted before 3 PM Arizona time.
Additional fee: 20% of the total cost + $3.99.
It’s important to note that these options only affect how quickly LetterStream prints and sends your mail. They don’t change postal or carrier timelines when LetterStream hands them off.
How The Stream Keeps Mail Moving
The Stream is LetterStream’s unified mailing platform, powered by StreamLogicˢᵐ—our proprietary methodology and standard of excellence that guarantees your mail is produced quickly, accurately, and reliably.
From the moment you upload a document, The Stream intelligently analyzes and sorts your mailing data so every piece is printed, inserted, and mailed with precision. Jobs are organized and processed through a consistent, automated workflow that handles each step with the same level of control and quality every time.
Because every job flows through The Stream’s structured system — backed by decades of production expertise and built-in standards like DocuWeaveSM and IntelliPrintSM — you get fast, accurate, and reliable mail production you can trust.
Mail Types You Can Send With LetterStream
LetterStream supports business-critical mail across industries, making it easy to choose the right format based on urgency, compliance needs, and message length.
First-Class Mail
Ideal for everyday business communication, such as invoices, statements, and notices that need timely entry into the mailstream.
Certified Mail
Used when proof of mailing and recipient accountability are required, which is common for legal, government, and regulatory notices.
Registered Mail
Used to send international mail with tracking, although tracking is not always guaranteed, and this is not a mail type we recommend unless absolutely necessary.
Postcard Mail
A practical option for short messages, reminders, and outreach where visibility and speed matter more than envelope privacy.
FedEx 2Day
Best for urgent, time-sensitive documents tied to contracts, deadlines, or critical business communication.
Each mail type flows through The Stream using the same reliable process, so speed and consistency remain the same regardless of format.
Why Processing Speed Matters for Your Business
Faster mailout reduces delays and lowers operational stress. It also helps teams respond quickly when deadlines or compliance requirements are involved.
Instead of reacting to mailing issues, organizations can plan with confidence. LetterStream is built to support consistency, even when urgency changes.
