Love it
Marcospolyart
It is very nice to work with and I love the integration with Ai. However, I still chose to use the older version of Spark because I often multitask and I need a lot of pop up windows open when I'm writing emails. This new version only allows you to type new emails inside of the app once at a time. The other feature missing is that I often place an image on the body of the email (cmd V) and then drag it to the bottom of the email to attach it. (the newer version also doesn't allow that). Last thing is that I can use the function quick view with space bar and switch with the keyboard arrowkeys to see the other attachments. I'll wait for them to improve it.

Spark is awesome!

I have had nothing but good experiences with the app and with the developer. Over the 2 or so years I’ve been using the app every day I’ve had a couple minor bugs. Each time I’ve emailed the support team, and gotten a prompt reply and a fix is usually deployed in the next few days. I’ve even gotten some new functionality. I really love these folks.
