(or call if they don't have faxes.)
Email, for obvious reasons, is restricted to constituents. Phones and faxes are not. For critical issues, consider adding faxes to your activist arsenal.
A note on free faxes: they must be from a valid email address. When you send a fax, they send it first to your email address and give you a link to click on. Only clicking the link you got by email will send the fax. Limit 2 per day, no more than 3 pages. For 10/month you can send more faxes and more pages.
