2.15. Ways to Avoid The Email Spam Filter

The larger emailing companies such as GMAIL, Yahoo and AOL have pretty high standards when it comes to receiving email. If there's something in your email which their systems don't like, it'll automatically flag up as a warning. There are technical things which can be done with your own email service such as SPF records and DKIM but you would need your email provider to help you sort this out for you.

There are things that you can do which will help:

Use a normal font size

Fonts that are too big or too small can trigger a Spam filter.   The reason is that many Spammers either try to hide text in an email with tiny font sizes or they use huge font sizes to make an offer.  Use a standard font size  to avoid Spam filters.

Watch your text to image ratio

Spammers often use images to communicate their offer because Spam filters can't read what is in the image.  Spam filters look skeptically upon emails that contain very little text but a large image.

Watch your link to text ratio

Spammers often send emails with little or no text and a link or numerous links.  When marketing with email, links are often a critical part of the email.  We usually need to place a link to the offer or to the content we are sharing with the email list.  However, be sure to include ample HTML text when including links or risk being marked as Spam.

Be careful who you link to

Just as it is important not to link to spammers on your website, it's doubly important not to do so in an email.  Linking to a known spammer is a surefire way to get a bad reputation. This can include also linking to your own social media sites.

Use clean code and proofread your text

Spam filters are keen to some of the more common spam formatting like red text in the body of the email or excessive use of underlining and bolding.

But they are also looking for anything out of the ordinary.  Things like blank lines, words with gaps (spaces) in them and excessive use of the same words can add to your Spam score. Also take care when formulating your subject line too.

All of the above is taken into consideration where your emails are rated the other end. You can ask your client to whitelist so they no longer receive the warning. It's also possible that over time, you'll automatically become a trusted sender. Your short email does include a lost of URL links which probably doesn't help.
