    JotForm marked as SPAM

    Asked by cmo on February 03, 2011 at 07:33 AM

    Recently all form enquiries submitted by email are being marked as spam by Spam Assassin (the best most accurate spam detector IMHO, also one of the most popular).

    Specifically this is the report score

    Content analysis details:   (4.2 points, 4.0 required)

     pts rule name              description

    ---- ---------------------- --------------------------------------------------

     0.8 HTML_TAG_BALANCE_BODY  BODY: HTML has unbalanced "body" tags

     0.0 HTML_MESSAGE           BODY: HTML included in message

     1.3 HTML_IMAGE_ONLY_32     BODY: HTML: images with 2800-3200 bytes of words

     1.7 MIME_HTML_ONLY         BODY: Message only has text/html MIME parts

     0.9 MIME_HEADER_CTYPE_ONLY 'Content-Type' found without required MIME headers

     0.1 RDNS_NONE              Delivered to trusted network by a host with no rDNS

    -0.6 AWL                    AWL: From: address is in the auto white-list

    ----------------

    So most of these reasons indicate problems with JotForm sender.

    This is a pretty serious problem because it means that I (and I suggest other customers using this or similar spam detectors) will not see the forms submitted.

    Regards,
    Charles

    Main reason seems to be that your spam filter does not like HTML emails. You can change the email to plain text.

    To change an email to plain text:
    1. Open the form on the form editor
    2. Click on "Setup & Share" tab on the top toolbar
    3. Click on "Email Alerts"
    4. Click on "Notifications"
    5. Click "Switch to Text Mode"
    6. Finish and Save your form.

    Well that's not really true. We send millions of HTML emails every week (we have that many opt-in customers), so we are completely aware of the art of generating spam-free HTML emails). Most emails are HTML nowadays and are not filtered or marked as SPAM as the JotForms ones are.  So the issue, as the report indicates, with Jotform emails are 'unbalanced HTML tags,' 'large' images with small amount of text, no plain text alternative included, incorrect MIME headers and no reverse DNS on your mail servers.  These are all technical issues that if solved would stop the problem. In fact fixing any one of those would take the emails under the SpamAssasin 'spam' critical limit.

    But thanks for the work-around info anyway. That's good to know.

    Thanks I noted these so that we can be careful about them when we create a new email template.
