Insightly Sidebar Update (12/14/18)
I wanted to provide an update in regards to the Insightly Sidebar as we come close to ending the year.
As a company, we're focusing all development efforts on our Insightly Gmail Add-on since it uses the current version of Gmail's API. Eventually, the previous API version will be discontinued. And as a result, the Insightly Sidebar will be removed on 12/31/2018.
You can find an overview of the Add-on here: The Insightly Add-on for Gmail.
There is always the option to use your Insightly mailbox address to save emails too.
Thank you, everyone, for the understanding and we welcome any feedback you'd like to provide.
