E-mail thank you letters after job interviews in medical sales, healthcare sales, biotech sales, medical equipment sales, DNA products sales, clinical diagnostics sales, laboratory products sales, medical supplies sales, or pharmaceutical sales are perfectly acceptable. But what do you do if you happened to leave without getting an e-mail address?

Google them: *@thecompany.com. For instance, *@phcconsulting.com would get you mine, and everyone else who works here.
