Our IRS liaison suggested we get an email account that will only be used for IRS (e.g., a gmail acct, or if your email provider lets you register more than one set it up). He showed a random page from the freely available IRS data base and I knew about five people on it; their email addresses were all there. The separate account will hopefully keep your real acct free of the urgent emails from potential "clients" who somehow picked you sight unseen and are sending a link to their tax docs, the incessant offers for CE courses, the barrage that comes from PTIN.org, and the phishing attempts that look like they're from irs.gov. I hadn't gotten around to setting up a separate account so I appreciate the IRS reminding us of the opportunity to change our address at PTIN renewal time.
