To prevent Zendesk's email from being consider spam, my company's SPF record contains include:mail.zendesk.com, but I still don't understand why, when they send email to my company, they say Zendesk "via" an email address at my company. There really doesn't seem to be any reason to not just use their own email address in the "From" header.
Thank you for your reply, but I think there is something I'm missing ...
They've probably just setup that once you've opted in for them to send emails on behalf of your domain, they will use it for everything relating to your account.
Yes, sorry, I meant the one simulating tritanopia - blue-yellow colour-blindness - not that the image itself was blue & yellow.
(It's just greyscale to me fwiw, as someone non-tritanopically (I've never been sure what, nor the optician, doesn't seem to be cleanly proto or deuteranomoly, perhaps some combination?) colour-blind viewing it filtered to simulate that. On some hand-wavey high level I lack the ability to see what's left after what I can see has been removed, I suppose.)
My workflow is Hugo, GitHub, AWS Amplify. All page creation is on my laptop. GitHub commits are done using the GitHub desktop app. Commits trigger AWS Amplify, and my site is updated.
