Why More Organizations Are Turning to First-Class Mail, Digital Records, and Affidavits of Mailing
A major change is happening in the State of Washington that could affect landlords, property managers, law firms, and businesses that send legal or compliance notices.
Washington recently passed House Bill (HB) 2664, which removes the requirement that certain landlord tenant notices be sent using USPS Certified Mail. Beginning June 11, 2026, qualifying notices may instead be sent using First-Class Mail.
This may sound like a small legal update, but it signals something much bigger.
Lawmakers are beginning to recognize that mandatory Certified Mail does not always help notices reach people successfully. In some cases, it may actually slow the process down or create delivery problems.
For businesses and property managers, this creates an important opportunity to rethink mailing workflows and save time and money while still maintaining strong proof of mailing records.
That is where Send Certified Mail can help.
What Changed in Washington?
Under the new House Bill, Washington landlord and tenant notices covered by the law no longer require USPS Certified Mail service in certain situations.
Starting June 11, 2026:
First-Class Mail will once again be sufficient for qualifying notices.
This means landlords and property managers may not need to use Certified Mail for every required notice moving forward.
The law was passed after lawmakers reviewed concerns about how Certified Mail was working in real-world landlord tenant situations.
According to legislative findings:
- Many tenants did not pick up Certified Mail
- Notices were frequently returned unclaimed
- Compliance costs increased
- Delays created problems for rental properties
Lawmakers concluded that mandatory Certified Mail requirements sometimes created delivery inefficiencies instead of improving communication.
That is a major policy shift.
Why Certified Mail Can Create Delivery Problems
USPS Certified Mail is still an important mailing service. It provides:
- Proof of mailing
- USPS tracking
- Proof of delivery
- Electronic Return Receipt options
- Restricted Delivery services
For many legal and compliance workflows, it remains extremely valuable.
However, Certified Mail also requires additional steps during delivery.
The recipient must:
- Sign for the letter
- Be home during delivery
- Retrieve the notice from the Post Office after a missed delivery attempt
This can become a problem in landlord tenant situations, because some recipients never retrieve the notice at all.
Property managers and Washington landlord groups have increasingly argued that notices delivered through regular First-Class Mail are often more likely to actually reach the tenant, because the mail goes directly into the mailbox without requiring a signature.
That concern played a major role in the new law.
Why First-Class Mail Is Becoming More Popular Again
Many businesses are now rethinking how they send important notices. For years, organizations often assumed Certified Mail was always the safest option. But lawmakers and compliance professionals are starting to focus on something different:
Did the notice actually reach the recipient?
In many workflows, First-Class Mail may improve the chances that the recipient will receive critical documents quickly. First-Class Mail also helps businesses:
- Lower mailing costs
- Avoid returned unclaimed notices
- Reduce delivery delays
- Streamline operations
- Save time
This is especially important for organizations managing high volumes of notices, rent increases, compliance mail, or operational communications. For some businesses, switching certain workflows to First-Class Mail can create major operational savings over time.
Why Proof of Mailing Still Matters
Even though some Certified Mail requirements are changing, businesses still need strong mailing records.
Organizations still need proof showing:
- When the notice was mailed
- Where it was mailed
- The date of mailing
- Compliance with legal requirements
That documentation is still critical for audits, disputes, operational records, and legal workflows.
This is why many businesses are now looking for a balance between:
- Practical delivery methods
- Lower costs
- Operational efficiency
- Reliable proof of mailing
That balance is becoming one of the biggest trends in compliance mail today.
How Send Certified Mail Helps Businesses Adapt
Send Certified Mail helps businesses send both:
- USPS Certified Mail
- USPS First-Class Mail
…through one easy online platform.
This allows organizations to choose the mailing method that works best for each workflow. For businesses moving toward First-Class Mail, Send Certified Mail offers an especially important feature:
A notarized Affidavit of Mailing.
This document provides proof that the mail piece was sent on a specific date and time.
For property managers, landlords, attorneys, and compliance teams, this creates stronger mailing documentation while still allowing them to use First-Class Mail instead of Certified Mail where permitted. That combination is becoming increasingly valuable as laws and compliance rules continue evolving.
What Is an Affidavit of Mailing?
An Affidavit of Mailing is a notarized document confirming that mail was sent on a certain date.
It helps provide:
- Proof of mailing
- Mailing timelines
- Compliance documentation
- Operational records
This can be especially useful for:
- Landlord tenant notices
- Rent increases
- Legal communications
- Financial notices
- Operational correspondence
For businesses using First-Class Mail, the Affidavit of Mailing helps create stronger documentation without requiring Certified Mail service. Many organizations now prefer this approach, because it helps streamline operations while maintaining defensible mailing records.
The Mailing Industry Is Changing
Washington is not the only place modernizing mailing rules. Across the country, governments and agencies are moving toward:
- Electronic notice systems
- Online portals
- Digital audit trails
- Timestamped records
- Centralized compliance systems
At the same time, legal discussions continue around USPS postmarks and mailing dates. Many organizations now understand that a USPS postmark may reflect processing time rather than the exact time USPS accepted the mail.
This has increased interest in:
- Acceptance Scans
- Digital records
- Online mailing systems
- Electronic proof of mailing
- Centralized reporting
The overall trend is clear:
Businesses want mailing systems that are easier, faster, and better documented.
Why Digital Mailing Records Matter
Traditional mail workflows often rely on:
- Paper receipts
- Filing cabinets
- Green card records
- Manual tracking searches
- Trips to the Post Office
Over time, these systems become difficult to manage, especially for organizations handling high volumes of notices. Modern businesses want:
- Searchable records
- Centralized documentation
- Online tracking
- Long-term archives
- Easier compliance workflows
Send Certified Mail helps businesses modernize these processes while improving organization and reducing manual work.
Why Businesses Use Send Certified Mail
Send Certified Mail helps organizations:
- Send Certified Mail online
- Send First-Class Mail online
- Access USPS tracking
- Retrieve proof of delivery
- Receive Electronic Return Receipt records
- Maintain long-term mailing archives
- Eliminate unnecessary Post Office trips
Businesses can manage notices, compliance mail, and operational communications from one centralized dashboard while improving visibility into mailing records. For property managers and organizations handling rental properties, this can help save time and reduce administrative burden significantly.
How Send Certified Mail Helps Businesses Meet Washington’s New Mailing Requirements
One of the most important details in Washington’s new House Bill is that qualifying notices must still be deposited into the United States mail from within the State of Washington. While the law removes the Certified Mail requirement, it does not remove the in-state mailing requirement.
For many landlords, property managers, attorneys, and businesses, this creates an operational challenge.
What happens if:
- Your office is located outside Washington?
- Employees work remotely?
- Your mailing operations are centralized in another state?
- Your team wants to send notices online instead of visiting the Post Office?
This is where Send Certified Mail provides a major advantage.
Send Certified Mail allows businesses to send USPS Certified Mail and First-Class Mail online from virtually anywhere while still helping support compliance with Washington mailing requirements.
Instead of printing notices, preparing envelopes, and making trips to the Post Office, users can upload documents online through one centralized platform. Send Certified Mail then handles the printing, packing, mailing, tracking, and documentation workflow on the backend.
For organizations managing landlord tenant notices, rental properties, rent increases, compliance communications, or legal mail, this helps streamline operations while saving valuable time and money.
Most importantly, Send Certified Mail also provides:
- Proof of mailing documentation
- USPS tracking
- Electronic Return Receipt options
- Long-term mailing records
- Notarized Affidavits of Mailing
The notarized Affidavit of Mailing is especially valuable, because it helps document when the notice was mailed. This supports operational record keeping for compliance workflows.
As more businesses move toward remote work and centralized digital operations, online mailing platforms are becoming increasingly important. Organizations still need to meet legal mailing requirements, but they also want easier workflows that reduce manual work and eliminate unnecessary trip to the mailroom and Post Office.
Send Certified Mail helps bridge that gap by combining online mailing convenience with strong mailing documentation and compliance-focused reporting tools.
