This blog uses Intense Debate to deliver comments to my email inbox. This is what the email looks like when I see it:
It does NOT tell me what website you've come from (sadly, because that would make reply commenting SO MUCH EASIER). I'm fairly certain the email it shows me is whatever you personally write in there, but I honestly don't know.
I read the emails. Sometimes reply, as it turns it into a reply comment on my blog, and then I delete them. I don't keep your email address or any of that. I do use gmail, so however Google "deletes" deleted emails is how it gets deleted. (Please don't go all "Hillary Clinton debate" about this on me, because I'm not qualified to answer questions about what or how deletion works.)
I'm not personally keeping your information. I don't think anything on this blog does, but I have no idea how BlogLovin' or Intense Debate works. If you feel the services may be an issue, it's okay to not leave me comments, or even to not visit. I won't take it personally.
