InboxGuru eMarketing Tips- Prevent Emails from going to SPAM

Engagement plays a huge role in email deliverability.

That’s because Web mail providers look at your engagement levels and recipient behavior when determining which emails actually make it to the inbox.

The average number of legitimate business emails received each day has remained static since 2015, but the number of spam emails that bypass security filters (spam that actually hits your inbox) has risen from 12 emails per day in 2015 to 16 emails per day in 2017. 

That means one out of every five emails sent either gets filtered as spam or blocked entirely.  One of the big reasons that it is getting harder to avoid emails going to spam is that spam filtering has become more rigorous. Web mail providers are simply cracking down harder on spam. However, the filters aren’t 100% accurate, so sometimes legitimate emails go to spam too.

Emails received verus spam from 2015 - 2019


(Don't get burned by a bad CRM implementation: watch now)

Top reasons emails go to SPAM

  •   Low Open Rates for that type of email

Top webmail providers have stated that they look at how many emails are opened and how many are deleted without being opened as a factor in their spam filtering decisions. This is the top reason for inbox placement issues, effecting 26% of email campaigns incorrectly flagged as spam.

If you have low open rates, your emails are at higher risk of being flagged as spam.

If you are sending the same type of email over and over (even to yourself) and you are not engaging with the email, it will get classified as spam.  This includes emails that you are sending to yourself or even people within your own domain.  If you are not opening and clicking on the email, the email engines learn this and will classify the content and the sender as spam.  So, always open your test emails!

  • SPAM trigger words

Example: amazing, cancel at any time, check or money order, click here, congratulations, dear friend, for only ($), free or toll-free, great offer, guarantee, increase sales, order now, promise you, risk free, special promotion, this is not spam, winner. 

  • HTML
    1. Use a maximum width of 600-800 pixels. This will make them look good in most email clients.
    2. Keep your HTML code as simple and clean as possible. 
    3. Keep your image-to-text ratio low. Images are OK to include in your email marketing campaigns, but never send image-only emails with no text.
    4. Optimize your images for email by compressing them first. Don’t use super high resolution images or other media with a large file size.
    5. Don’t use obscure fonts. Stick with fonts that work across platforms, like Arial, Verdana, Georgia and Times New Roman.
    6. Optimize for mobile. 

  • Subject lines

 You can use InboxGuru' s tagging and tracking statistics in order to measure A/B testing and improve your content.

  • No unsubscribe link

Make sure you are using unsubscribe links and headers in your emails. Many ESPs (particularly Hotmail) pay attention to this and if they are not there, you are likely to get filtered.

You can always use InboxGuru's auto unsubscribe handling if you don’t want to deal with this on your end.Gmail pays particularly close attention to Message ID and Received headers. Message IDs that are formed incorrectly (without brackets <> and with wrong domain after @) can make Gmail think you are a spammer. The simplest way to create the right Message ID with InboxGuru is to not include one. Then InboxGuru will create a perfect Message ID for you.


Prevent Form Spam

CRM 101 VideoTo prevent form spam, InboxGuru has provide us a very cool trick. It involves placing an extra text box on your page that will use CSS to hide it.

SPAM engines read your forms layout and they inspect all of the form inputs.  This trick will allow the bot to pick up this invisible field and submit it.  If InboxGuru finds data in this invisible field, then it will be rejected.  A normal person would not normally be able to see this hidden field much less submit data in it, so this trick is foolproof (unless the bad people making these bots read this help article).

  • Add this CSS to your form:

inboxguru { display:none;}

  • Add this field to your form (anywhere after the <form tag and before the </form

<p class="inboxguru">Leave this empty: <input type="text" name="InboxGuru" id="InboxGuru" /></p>

Deploy your form and make sure you cannot see this field. Test your form and make sure that your data is getting to InboxGuru.
