We know that legitimate email sent with valid SPF and a DKIM signature often breaks in transit. SPF will fail any time mail is forwarded – via a mailing list, a forwarding service used by the recipient, or just ad-hoc forwarding. DKIM will fail any time the message is modified in transit. That can be obviously […]
I just added a DMARC validation tool over on tools.wordtothewise.com. You can give it a domain – such as ebay.com – and it will fetch the DMARC record, then explain and validate it. Or you can paste the DMARC record you’re planning to publish into it, to validate it before you go live. If you’ve not […]
Happy New Year! We’re looking forward to some interesting new projects this year, both for our clients and for Word to the Wise. Stay tuned! December was a slow month for blogging, with everything going on. But we’re back on the horse now and ready to blog for 2017. List and subscription management continue to […]
One of these things is just like the other Canonicalization is about comparing things to see if they’re the same. Sometimes you want to do a “fuzzy” comparison, to see if two things are interchangeable for your purposes, even if they’re not exactly identical. As a concrete example, these two email addresses: (Steve) steve@wordtothewise.com “Also Steve” […]
A bit of older news, but worth a blog post. Early in August, Gmail announced changes to the inbox on both the web interface and the android client. They will be pushing authentication results into the interface, so end users can see which emails are authenticated. These are not deliverability changes, the presence or absence […]
There are so many moving parts to ensure good email deliverability. Email marketers need to know marketing, they need to know email and they need to know design. The technical bits of email can be a challenge to learn, and many folks who write tutorials and How-Tos write them for a different audience than marketers. One […]
I was looking for some references today back in old blog posts. This means I discover some old links are dead, blog posts are gone or moved, and information is lost. In this case it’s a post by J.D. Falk on deliverability.com. The link is dead (it looks like the whole website is dead), but […]
Dear Laura, I’m a little confused by the term “no auth / no entry”. Gmail and other major receivers seem to be moving towards requiring authentication before they’ll even consider delivery. Does this just mean SPF and DKIM, or does this mean the much more stringent DMARC, as well? Thanks, No Shirt, No Shoes, No […]
Dear Laura, I heard recently that both Gmail and Yahoo will require DMARC authentication in early 2016 or images will be automatically blocked. Is that correct? And if so, do you know when they will be requiring DMARC? A DMARC-Overwhelmed Admin Dear Overwhelmed, There are three things going on here, all of which are […]
I’ve been hearing a lot lately about DMARC. Being at M3AAWG has increased that. Last night we were at dinner and heard from the next table “And they’re not even publishing DMARC!!!!” I know DMARC is the future. I know folks are going to have to start publishing DMARC records. I also know that the […]
