The Shopkey apps!
This is one of my favorite.
I considered it as one of the remarkable apps that I just installed. In messenger marketing, it is very helpful! Less keys to type in, just hit the keyword or first three letters of the product, click the picture and it is ready to send the link from my shopify store to my Customer. I will certainly keep this app always link to my store. As long as it is free:).For the moment my store only affords free apps. But time comes when it is off the ground I will certainly consider apps that offers monthly subscription.
