Who is allowed to send mail as you
v=spf1 redirect=_hspf.hubspot.com
Your SPF record doesn't authorize Google to send mail. Even though FrostSender connects via Gmail, your SPF check will fail — recipients will treat your mail as suspicious.
Your SPF record doesn't end with an enforcement mechanism. Unauthorized senders won't be challenged.
