>Even after all that, there's some chance that an email from my server will be marked as insecure/spam Don't I know it. This happened to us but not with Google. We use Exchange Online (Office365) and have DKIM, SPF headers configured. At some point our emails stopped being received by bell and cox emails addresses ... sporadically but sometimes for days at a time. It turned out that the spam filter provider (used by bell and maybe cox) correlated one innocuous phrase in our confidentiality notice (which is appended to all outgoing email signatures) with spam and therefore marked the entire email as spam as well.

To be honest I don't like this confidentiality notes and from what I've read (not a lawyer) they don't have any practical effect either.

  I always giggle when I see those. Especially the part about how "if you are not the intended recipient, you are ordered to destroy all copies of this message." It's my computer. You sent the bad message. You're in no position to "order" me to do anything. I suspect they're mandated by self-important Lower Middle Manager of the Year Award nominees, not actual legal departments. The sort of people who never do anything but push papers around, yet put a bunch of meaningless initials after their name in e-mail signatures because they went to a conference.

    And cargo-culting. Most email templates are set up from old instructions hanging around confluence or a wiki. And they are rarely, if ever, actually vetted by legal. It 'feels' good, so it stays.

You're in no position to "order" me to do anything. Best case scenario, someone listens and destroys the message. Worst case scenario, the company is no worse off than if they hadn't included the disclaimer. Makes sense from my perspective.

  Forget it, Jake. I have a doctor who has a big old footer, "If you have any questions, reply to this HIPAA-compliant email." I explained the problem with this in detail, but it's still there.

> we use Office365 and don't have this issue I'm not surprised Microsoft's IP range is known by google. Sending from sendgrid, mailchimp, and a few others that send a lot of mail also works. It's when a new player wants to get in the market (or god forbid, an individual with their own nerdy server) where the trouble arises.

  To clarify, I wasn't arguing that sending email to Gmail is easy especially if you're using an independent provider that is unknown to Google - which is how you're framing my response as (why?). I was acknowledging the general issue of dealing with modern email problems and how opaque the underlying systems are.

  Postmark requires a minimum of 50K emails a month for a dedicated IP address, and they state that minimum is for quality reasons. You won't get a good enough reputation on your IP without it. That should give people an estimate of the required volume to get decent delivirability rates to big providers.
