What can I do for Gmail emails stop going to Spam?

I have come across different solutions for this problem, but none have worked for me. When a user registers in my website, we automatically send him a "Verify your account" email which has a button and at the footer there is a link to our website. When the user clicks the button, he is directed to our website. We're using gmail with our domain email (@mydomain.com), and we can see that over 50% of emails go directly to Spam. We have worked around a couple of solutions, but none are working. We don't want to use a service such as SendGrid.

This is how we create and send our emails (step by step)

  1. We created an html/css email using a Zurb's template.
  2. We used the Zurb Email Inliner to make the CSS inline.
  3. We use the NodeMailer library to send the emails
  4. Finally, the messages are signed using DKIM

As I've mentioned before, most emails end up in Spam. Any thoughts?

Solution

  • .1 First have only the DKIM is pretty much useless if you don’t also have an SPF as they work in conjunction:

    .2 Then you need to Set up an outbound mail gateway

    Furthermore take not of this:

    • An incorrectly set Auto forwarding or routing setting. Like dual delivery or automatic responses.
    • Enter in the field "CC" or "BCC" when composing a message with too many email addresses at a time.
    • Not having the SPF and DKIM values set correctly.
    • Recipient addresses mark your emails as Spam, includes either a manual action or an automatic action such as a filter they have enabled or a device (very often phones) that automatically marks as Spam.

    Also important to note that you shouldn’t use HTML and CSS to hide content in your messages. Hiding content might cause messages to be marked as spam. as explain in this article (and I suggest you to read it through):

    **EDIT**

    I forgot to mention that you can run some test if you send email to Gmail using The Postmaster Tools

    keep in mind that is only towards Gmail account, but you can open few free one for test purposes
