Both Riley & Grey and Glö are excellent choices for young couples who want to make their wedding invitation modern but classy. Riley & Grey prefers an artsier approach with innovative design templates and an innovative yet easy to use editing tool. Glö, on the other hand, is about customization. You have access to tons of features, functions and designs, and with enough time on your hands you can come up with something genuinely unique. Riley & Grey is a bit expensive, charging you $35 each month. Glö isn’t much better, as their service cost you $29.99 per month.
