With full DNS setup (recommended)
Replies come from support@yourstore.com. SPF + DKIM authenticate the send so Gmail/Outlook don't mark it spam.
With Gmail forwarding only
Replies still come from your Gmail address — but ensure 'Send mail as' is configured in Gmail so the From field is your branded email.
Without any setup
Replies come from a Taskra-branded address. Not ideal — finish DNS setup to fix this.
