Hi there ann mcguire , thank you for submitting to our Feature Requests!
Integrations with Mailchimp and Canva are both available on our platform. Regarding Insightly, we don't have it at the moment, but you can implement it with the help of external codes through the Custom HTML Element or the Site Settings App > Code Injection section!
You can find Mailchimp and Mandrill (a transactional email platform built by Mailchimp) in your Dashboard > Integrations App. You also have the option of connecting the Form and Subscriptions Elements to your Mailchimp account, by simply choosing your List ID from the dropdown menu.
By navigating to the Media App, you'll see the Canva tab accordingly. Just log in to your existing Canva Account to enable uploading your graphics directly to your website!
