Yes, I've worked with Instantly and HubSpot together, and I agree the native integration leaves a lot to be desired, especially for real time syncing of outgoing emails' one workaround that's worked for me is using a tool like Zapier or Make formerly Integromat to create a custom automation flow. You can set up a zap that captures Instantly email activity via webhook or Gmail integration, depending on your setup and then logs it in HubSpot as an engagement.
