When my wife is out of the house the only reliable way for her to contact me is by e-mail. I'm on Gmail. But when I'm writing on my Mac I don't like to be distracted by the internet and will either minimise the browser, usually Chrome though I'm attracted by Opera, or prevent it from opening with 1Focus. It there any way I can be informed by a popup etc that I have an e-mail from her (and only her), ideally when Chrome is closed but I would settle for the option of having Chrome merely minimised. I don't use Apple Mail. Thanks.
