I used keys.tab to reach that element but it was unable to enter text in that textfield using senkeys("xyz#gmail.com)
I used scroll method
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("document.getElementById('youama-email').scrollIntoView(true);");
some exception occur
3.I used Moveto element method but got exception
WebElement element = driver.findElement(By.id("youama-email"));
Actions
actions = new Actions(driver);
actions.moveToElement(element);
actions.click();
actions.perform();
// Initialize Javascript executor
JavascriptExecutor js = (JavascriptExecutor) driver;
// Scroll inside web element vertically (e.g. 100 pixel)
js.executeScript("arguments[0].scrollTop =
arguments[1];",driver.findElement(By.id("<div-id>")), 100);

fields that will appear after scroll [![enter image description

Try this code. I think what you didn't do was to wait for the element to be visible which i did. See the below code. It is running correctly.
WebDriver driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.get("http://wyomingvapor.com/");
driver.findElement(By.xpath(".//*[#id='header']/div/div[2]/div/a[1]")).click();
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//*[#id='y-to-register']/input")));
driver.findElement(By.xpath(".//*[#id='y-to-register']/input")).click();
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//*[#id='youama-firstname']")));
driver.findElement(By.xpath(".//*[#id='youama-firstname']")).sendKeys("xyz#gmail.com");
Thread.sleep(2000L);
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_TAB);
robot.keyRelease(KeyEvent.VK_TAB);
robot.keyPress(KeyEvent.VK_TAB);
robot.keyRelease(KeyEvent.VK_TAB);
robot.keyPress(KeyEvent.VK_X);
robot.keyRelease(KeyEvent.VK_X);
robot.keyPress(KeyEvent.VK_Y);
robot.keyRelease(KeyEvent.VK_Y);
robot.keyPress(KeyEvent.VK_Z);
robot.keyRelease(KeyEvent.VK_Z);
