The U.S. Legislative System
Congress is the part of the U.S. government that writes and passes laws.
It has two parts, called chambers.
They work separately but both have to agree before a bill can become a law.
100 senators, 2 per state, with 6-year terms
435 representatives, divided by population, with 2-year terms
What this means for you: When you contact Congress, you are reaching out to your specific representative in the House and your two senators. Congressional offices pay the most attention to people who actually live in their district or state. Signal Post Now automatically sends your postcard to the right person.
How a bill becomes law
Between 10,000 and 15,000 bills are introduced in Congress every two years. Less than 5% of them become law. Most never even get a vote. Knowing this process helps you understand when your voice can actually make a difference.
Any member of the House or Senate can introduce a bill. In the House, the member literally drops it into a wooden box called the "hopper." The bill gets a number (H.R. for House bills, S. for Senate bills) and is sent to the relevant committee.
A small group of lawmakers called a committee reviews the bill. The committee chair decides whether to even hold a hearing on it. Most bills never make it past this stage. If a hearing is held, experts testify and the public can comment. This is one of the most important steps in the whole process.
If the committee moves forward, members meet to edit the bill line by line. They can add, remove, or change parts of it. Then the committee votes. If the bill passes, it goes to the full chamber. If it fails here, it usually dies.
In the House, the Rules Committee decides how the bill will be debated: how long, what changes can be suggested, and under what conditions. In the Senate, the Majority Leader controls the schedule. Getting a bill to the floor often requires agreement from all 100 senators.
The full chamber debates the bill. In the House, debate time is limited and tightly controlled. In the Senate, debate can go on indefinitely unless 60 senators vote to end it. Members can also suggest changes, called amendments, during this phase.
A simple majority is needed in each chamber. That is 218 votes in the House, or 51 in the Senate (60 to get past a filibuster). If the bill passes, it moves to the other chamber and starts the process all over again. Both chambers must pass the exact same version of the bill.
If the House and Senate pass different versions of the bill, members from both chambers meet to write one final version. Both chambers then vote on that unified version. Contact from constituents still matters during this phase.
The President has 10 days to sign or veto the bill. If signed, it becomes law. If vetoed, Congress can override with a two-thirds vote in both chambers. If the President does nothing and Congress is still in session, the bill becomes law on its own. If Congress has already gone home for the year, it dies. This is called a "pocket veto."
An action window is a point in the process when a decision is still being made and your input can actually reach the right people in time. These windows often close within days. Signal Post Now watches tracked bills around the clock so you do not have to.
Why physical mail matters
Congressional offices get hundreds of thousands of messages every year. Staff sort them by type. Research consistently shows that physical mail gets taken more seriously than digital contact. Here is why.
These are copy-paste messages sent by thousands of people using the same template. Most offices group all of them together and count them as one tally mark, not as individual opinions.
Calls are recorded by staff. A personal, specific call carries more weight than a scripted one. But most people will not call repeatedly, and offices track volume more than content.
Physical mail is logged one by one. A staff member has to handle it. This signals that you are genuinely motivated — and that you took real effort to be heard.
The platform
Signal Post Now handles the monitoring, timing, printing, and mailing. You decide whether to send.
Sign up with your email address and home address. We use your address to identify your congressional district and match you to your House representative. You are also automatically connected to your two U.S. senators.
Pick one or more policy areas you care about, like healthcare, housing, climate, immigration, or education. Your choices determine which bill alerts you receive.
Our system checks tracked bills every four hours for status changes. When a bill enters an action window, like a committee vote or a floor vote coming up, we flag it right away.
You receive a plain-language email explaining the bill, its current status, and why this is an action window. The email links directly to the bill's page on your dashboard.
On your dashboard, you can browse all active bills, not just the ones that match your issues. Filter by "All bills," "Your issues," or "Saved." Each bill page has a plain-English summary, the current status, and your rep's information.
When you are ready, click Send. You choose whether your postcard supports or opposes the bill. We generate a physical postcard with your name, your address, and your representative's official DC mailing address.
We use a commercial print-and-mail service called Lob to print your postcard and send it through USPS First Class Mail. Your postcard is a real, physical piece of mail going to your representative's Capitol Hill office.
The postcard's journey
Your postcard travels from your screen to your representative's desk in four steps.
Your postcard is printed in full color with your name, your message, and your rep's official address. This usually happens within one business day.
Your postcard enters the USPS First Class Mail system, addressed to your representative's Washington DC office. You can track it in your send history.
All Capitol Hill mail goes through an off-site safety facility before delivery. This is standard practice and is factored into the 1–3 week total delivery window.
Staff at your representative's office receive, sort, and log the mail. Constituent mail totals are reviewed by the member and tracked by issue.
A note on expectations: Signal Post Now does not claim your postcard will change a vote. What we can say is that it will be received, counted, and added to the record your representative's office keeps on what their constituents care about.
