    Hi! If you're using HTML if you had any hidden text in your email, this warning is triggered in SpamAssassin and likely made your spam score higher.

    If you’re using HTML emails, you don't want to use invisible text. You'll want to be sure that your text colors and sizes are distinct enough and large enough to read. Invisible text is often identified as a sign of spam.

    Does this also include stylings for Outlook clients?

     

    Like a CTA button that needs to work for html email clients as well as Outlook ones? :

     

    <tr>
    <td align="center" width="100%">
    <table role="presentation" width="100%" cellspacing="0" cellpadding="0" border="0" align="center" style="min-width: 300px; width: 100%; max-width: 752px;">
    <tr>
    <td align="center">
    <div><!--[if mso]>
    <v:rect xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="urn:schemas-microsoft-com:office:word" href="https://google.co.uk/" style="height:68px;v-text-anchor:middle;width:286px;" stroke="f" fillcolor="#22662a">
    <w:anchorlock/>
    <center>
    <![endif]-->

    <a name="Learn More Button" href="https://google.co.uk/" class="CTA-Button" style="display:inline-block;width: 286px;border-radius:4px;margin:0;padding: 13px 0; background-color: #22662a;line-height: 26px; color: #ffffff; text-align: center;text-decoration:none !important;">Learn More</a>
    <!--[if mso]>
    </center>
    </v:rect>
    <![endif]-->
    </div>
    </td>
    </tr>
    </table>
    </td>
    </tr>

    This could be the pre-header and can be ignored.

    Users have been receiving a lot of error messages regarding "Font too small to read, no rDNS". Not entirely sure what this means.

    Same here Carlos. Our users are getting many more Spam Assassin warnings recently, including "Font too small to read, no rDNS"

    Kristin Connors - Yes! Support identified it as "false positive" and can be ignored, but I'm hoping that can corrected? I continue to get questions on it and I advise to ignore, but it still creates doubt in the system. Users like to know their email is safe to send.

    Ditto. I literally just got an email in my inbox about this as I'm typing. Spam Assassin is creating more problems than it's solving.

    Same here Carlos and Kristin! I think it was since yesterday we are getting more spam scores on "Font too small to read, no rDNS" pretty much every single current on going email campaigns have this spam score now. We are not sure how it happened because all those campaigns have been running for a while and never seen this spam score when we did health check before?  Is it something to do with our public rDNS?

    I found this interesting thread on their knowledge base - https://help.goacoustic.com/hc/en-us/community/posts/360047416113-Email-Health-Spam-Score

    According to one post from Erinne Mejia, who I had the pleasure of meeting a while back at a conference and who is very knowledgeable in the system. She mentions the alert is legit and there is a font-size:0px or 1px is in a div tag and a fix for outlook. If that exists in your template, it can be ignored. In addition, if you are not seeing a spike in soft bounces or a dip in open rates, it's also safe to ignore the alert. Again, more on this can be found in the thread, but after reading Erinne's post, I'd say it's safe to ignore given it sounds like an outlook fix.

    What I can gathering from this is that the Spam Check and/or Spam Assassin is basically useless... Telling users to ignore warning this or ignore that warning is not acceptable.

    The tool should not blindly flag a warning on content elements such as the preheader which their use is a recommended best practice for improving open rates!

    Additionally, I spent 2 hours trying to track down and "es are not es" warning and  was later to ignore it.

    If we can not rely on the spam score, what other options are available to aid in diagnosing falling open rates.

    What does "excessively long line + hidden text" mean?

    Hi Olivia

    The excessively long line + hidden text error is shown due to using white text, and excluding the background-color attribute on every text element. Spam Assassin doesn't like this, so instead of looking at the parent element, it defaults it to white. So Spam Assassin says "white font color on white background - hidden text!" when in reality this is not true.
