What to include

One issue per fax. Reference a specific bill number or regulation if you have one — offices sort mail by topic, and a single clear ask gets tallied accurately.
Your name and mailing address. Senate offices prioritize constituents; an address in Hawaii signals your position should be counted as a Hawaii voter.
Keep it to one page. A short, specific message — what you want the senator to do, and why it matters to you — is read fully and logged.

Why fax still works for Senate offices

Security screening delays physical mail to Capitol Hill by weeks, and email forms bury individual messages. Fax arrives the same day with a timestamped transmission record, which is why offices — and the advocacy groups that track them — still publish fax numbers. Sending online, you get the delivery confirmation without a fax machine.
