Authenticating Sendgrid Emails with DKIM and DMARC

Why are my Sendgrid emails going to Spam?

If you have a problem with Sendgrid emails not going to spam, that is, going to the spam folders of your recipients, then it is very likely an issue with your email authentication. Emails failing authentication, be they failing SPF, failing DKIM, or failing DMARC is common, as SPF, DKIM, and DMARC are often not properly implemented by domain administrators. Often, the main cause of Sendgrid emails being blocked is due to the Sendgrid emails failing DMARC, which in the case of Sendgrid, is usually due to a misconfiguration of DKIM.

How to stop Sendgrid emails going to Junk.

The first step to preventing sendgrid email going to spam is to retrieve a failed message and access its header information. This will allow you to quickly diagnose whether any authentication issues such as DKIM or DMARC are flagging your email as spam, instructing the recipient sender to move it to junk. Simply paste the email headers into our free Stellastra Deliverability Tool, which you can use freely with no log in required. Our deliverability tool should allow you to avoid Sendgrid emails from going to spam, or at least rule out authentication as the issue.

How to remove via sendgrid.net, via sendgrid.com, and via sendgrid.me

Another example of where a Sendgrid DKIM misconfiguration is to blame, is if your recipients report seeing the message as "email via sendgrid.com", "email via sendgrid.net", and "email via sendgrid.me", often these "sent via" emails appear alongside a grey box containing a question mark instead of your company logo, demonstrating that the recipient is unable to authenticate the email. If sent with such a "sent via sendgrid.com", "sent via sendgrid.net" tag the emails typically end up in spam or junk. The Stellastra Email Deliverability tool above will confirm this prognosis, however, you may also wish to configure DKIM for Sendgrid by logging in to your SendGrid account to check to see if you have followed this following article to configure your sendgrid dkim setup to authenticate your domain.

How to stop Sendgrid Failing DMARC

To ensure that your Sendgrid campaigns pass DMARC and get delivered to your prospects, it is important to ensure that DKIM passes authentication for your domain. A common mistake is to sign an email with Sendgrid DKIM keys. However, in order for Sendgrid email to pass authentication, it is necessary to use your own DKIM keys as per Sendgrid's own guide. If you wish to verify the above, paste the message headers for a failed Sendgrid message into our Sendgrid email testing tool
