The complexity of an issue and timing determine whether it is best for you to call, write a letter, or send a message via social media channels.
Phone Calls
If a vote on a particular issue is imminent, calling is probably the best bet. Messages communicated by phone calls should be simple, such as “vote yes on x bill” or “please vote no on amendment x.” It is best when communicating by phone to only address one issue.

Written Communications
When an issue is being considered by a committee or the full House and/or Senate but a vote is not taking place in the next few days, letters sent by email are a good way to share your viewpoints with elected officials and their staff members. Email arrives faster than mail, and computer systems allow staff to manage email communications more efficiently, thus staff prefer it.
When writing, the ABCs of advocacy are important: be accurate, brief, and clear. Clearly state what you want the legislator to do, such as take a specific position on a bill or offer an amendment. Also, make it personal. Start the letter by identifying yourself as a constituent and a scientist (for example) and explain why the issue matters to you (and should matter to them!). If you have facts about the district or state relevant to your position, include that information. This personal information should be at the beginning to draw the reader in.
The Biophysical Society has an online action center to make sending letters easy and often provides drafts you can use. It is important to personalize these. It can be two to three sentences, but it signals to the reader that the writer is invested in the issue and it also gives them a hook. Personal stories are very effective at making an abstract policy issue relevant to a staff member of an elected official.
To compose your own letter, select “Find officials,” check the individuals you would like to write to, and select compose message.
Social Media
Using Twitter or Facebook can be a good way to engage members, and unlike a letter, this form of communication provides a public forum that provides more visibility and makes it very hard for a Congressional office to ignore. Simple “yes” or “no” messages work well on social media, as do links to position statements of organizations to which you belong, and thank you messages. Like what your Congress person did? Give them public recognition with a Twitter or Facebook thank you. On Twitter, lead with the staff member’s twitter handle. On Facebook, go to the legislator’s page to post your message.
