One of the most frequently asked questions is why don't my sources align?
There can be dozens of reason why this can happen but here are the tools that I use in order to rapidly troubleshoot each sending source.
Conduct this test with each and every sending source that your business uses (Mailchimp, Sendgrid, Zoho, Office 365) and check the results page to see where there are possible alignment issues.
https://www.hardenize.com/ - enter your domain name and check the email section SPF / DKIM. Make sure that they are not grey. Ideally, they will be green, but you may have issues with the record. Use the feedback from this tool to fix or update your DMARC and SPF policies.
Ideally, your results should show:
You don't really have to worry about any of the other sections for this test.
If you have a failure in one or more of these sections there are technical issues that you will need to fix on your sending account.
Note: Some sending sources or services are unable to send DMARC compliant emails check https://dmarc.io/sources/ to see if the service you are using is capable and to find a quick link to a guide on fixing the issue.
Even if DKIM passes I ALWAYS open up the DKIM section to ensure that the domain listed in the d= section is your own domain name and not the domain name of the sending service.
It is very common for services like Office 365 to send email on their onmicrosoft.com domain not on the customers custom domain. Ensure that your d= is your own domain. And update your sending provider if it is not d=yourdomain.com.
SPF alignment issues
If the tool reports an SPF problem head to https://vamsoft.com/support/tools/spf-policy-tester
You will enter in the IP address that was not in your SPF record and an email address at your domain name. The service will simulate an SPF lookup and provide a pass / fail at the bottom of the report.
