Hi @AliceBArcos,
Thank you for clarifying.
If you would like to detach from Squarespace completely you would need to purchase Google Workspace separately. This would allow you to continue to use Gmail as your email provider and still maintain the use of USER@blanket.mindset as your email.
This will add to the complexity of this conversation a bit because once you leave squarepace, you will still need something to host your DNS. Usually, companies will host their DNS with the place they purchased their domain name (GoDaddy for example) or use another service, such as Cloudflare. Once this is set up it will point your website to HubSpot and point your email to the new Google Workspace you have set up. This will also allow you to add the required SPF record. As mentioned, probably more complex than can be easily supported in this thread.
As another option, you could leave your email and DNS with Squarespace (I think) and still add the records there. Here’s an article I found that is pretty decent at explaining the customization of Squarespace DNS settings: How to Add DNS Records to Squarespace | A Step-by-Step Guide
The last option would probably be the most straightforward, but if you do plan to leave Squarespace completely, you might have to take the other steps.
