Updates for our Magento 2 Site

We have a Magneto 2 site which needs a few 'Tweaks' and two fixes. Fixes: 1) Email is not being sent 2) Web Setup Wizard gives a 401 error Tweaks: 1) We would like 'Configurable' products to show the range of prices for items in that grouping ($2.95 - $4.95) instead of a single price. 2) Lists should be reactive so if the screen can fit 15 tiles, it shows 15 tiles. If it can only fit 12, it shows 12.
