Make email the default alert in Calendar

I would like the default alert in Calendar to be by email at a given time and at the moment it is a multi-step process to set this up which I have to go through each time I want to add a new event. I understand that this is not a feature available “out of the box” so does anyone have a script that would do this? I am a complete dullard as far as scripting goes but would be most grateful if anyone can help me out here. I am operating OSX 10.11.6. Many thanks.
