I understood that Precedence header is important to ensure email delivery, but I could not understand what the difference between "bulk" and "list" values.
Since I'm sending bulk emails to a mailing list of subscribers, I assumed "list" to be preferable but I had no chance to find information about the "list" value, while Google only talks about "bulk" value for Precedence header in its documentation dedicated to bulk email senders.
May I have some clarification / suggestion? Thanks
