So as a standard test I added a mail-tester.com email address to a Klaviyo list, and included it in a test campaign send.
The result is a SpamAssasin error:
Any ideas can I debug further and/or fix?
I’m already somewhat familiar with the techy side of email headers, deliverability, DNS, HTML, networking etc having worked in a tech support role - but just wondering if this is something where others have experienced and/or already fixed it.
I did have a ticket related to this, but got told “it’s a Shopify issue” which is just not very helpful.
