Customising Email Confirmation Template

Hi All,

Thanks in advance for this. I am looking to customise my email confirmation template.

At the moment it comes from no-reply@squarespace (I definitely don't want that)

Second the email is currently sending confirm subscription and I want it to read as confirm email.

Add logos, social media links etc. 

Anyone have any ideas?

I'd like an answer to this also. How to change the "Subject Line" text. 

i'm also looking for some insight on this.
