We receive so many messages that it helps a lot if we can tell right off the bat if the sender is an existing customer. Not everyone includes order numbers, so this helps reduce tracking down and connecting messages with their appropriate orders.

Uncaring customer service, unless of course you pay for it.

I am running a couple of stores with shopify and bigcommerce. I have installed Zendesk on my shopify stores including Jaipur Hair & Instalength. But their customer support sucks and i personally do not recommend. They didn't treat customers like customers when it comes to proper support we require being in India.
So instead of Zendesk, I strongly recommend Freshdesk or Freshchat. I have lost whatever i have paid them in front for annual plan. They didn't resolve the concern i have asked them to do instead they are like all the payments are non refundable.
Please do not waste your time with them.

Keeps all of my customers in one location on multiple sites. Works great.

Can't live without it. Helps so much with customer support.

If you have any issues with customer service this program solves it all. Check out my site https://MajorLeaguePets.com

Saves a lot of time, especially during non business hours.

Great app for our store. Works great and we never have any issues.

The app is really working well in terms of feeding data to Zendesk, but it is really heavy on the pagespeed. Hope that zendesk will look into this.
