A: Hi,

we don't have a native integration to Hubspot. We will let you know when we will add this integration to our roadmap.

I don't know so much about Encharge, maybe this comparation between Mailchimp and Acumbamail can help you:
https://acumbamail.com/en/mailchimp-vs-acumbamail/

Anyway you can try Acumbamail for some days, I am pretty sure that you will like us :)

Best,
