I want to send a birthday email and chose one of the birthday templates to do so, but I don't want a button at the bottom. Is there a way I can delete that button or do I have to just choose another template? I am using Google Chrome 48.0.2564.103
If you are using the Birthday | Blue (or any other color) template, the button is built into the code so there is not a way to delete the button. There are some other Birthday templates available in the Template Gallery that do not contain a button block that you can choose from or you can create your own Birthday template starting with one of our blank templates.
You can "hide" the button in that template by matching the the color of the Call to Action block, the button and button text color, however, the button block will still be in the template and will look like something is there if you hover your mouse over that area. Take a look at the Support Copy campaign on your unsent tab where I matched all the colors in that block. If you click the Preview button and hover your mouse on that area, you will see how it will still look as if there is something there to click.
It may be best to either recreate the template using a blank template or to use another available Birthday template from the Template Gallery. Feel free to give me a shout with any questions or if there is anything else I can do to help!
