bart's blog: Sending HTML emails to multiple subscribers via Django

  • jonknee · 1 year ago
    Sending mass email is a good way to get blacklisted by ISPs. It doesn't need to look like spam if it gets sent like spam. It's a fairly complicated task, but one of the most important things is pretty simple: don't send email to an address that has bounced. Also make sure your DNS entries are on the up and up, SPF and Sender ID records can help a lot.

    @jonkee: You're definitely right on that and I'm not advocating spamming
    here, just using django's mailing techniques to send out to your user list.
    You could always go further and manage the bounced back emails to be removed
    from your list and so forth so you don't mess up your

    Can you explain more about the DNS entries, SPF, and Sender ID? I'm curious
    myself

    Sadly the spammers have made it so something as simple as sending out a newsletter to your members can make your deliverability rates dive (which really hurt when you need to send out a login recovery email or something.

    SPF is an open spec that lets you announce what servers are allowed to send email for your domain. There is a nice wizzard to get yourself set up: http://www.openspf.org/

    Sender ID is basically the same thing but with support from Microsoft. With Hotmail's large market share it shouldn't be ignored. http://www.microsoft.com/mscorp/safety/technolo...

    You'll also want correct reverse DNS.

    This stuff is too hard to research because of all the scuzzy marketers out there. A real shame, it should not be hard to serve legit email to your users. This is why there are firms out there like AuthSMTP, it's just a huge task to keep up on.

    Thanks jonknee, that's extremely helpful. I didn't even have the slightest
    clue on any of those topics, I almost feel bad writing this quick post :-)

    I'm going to look over those links in my spare time, thanks again!

    I should also mention you can sign up to get spam reports from some of the majors. It's pretty handy:

    Even if you don't send spam you can still get spam reports. For example, a lot of AOL users like to mix up the "spam" and "delete" buttons which can cause email senders considerable difficulty.
