Wesley Hilliard at Apple Insider covers a story that has certain political fundraising groups up in arms: Apple's upcoming iOS 26 release will start automatically sorting messages from unknown numbers into a new "Unknown Senders" category. That means no notification ding, no badge on the Messages app. Just a quiet little folder of messages that most people will never look at.| Spam Resource: All Things Deliverability
Every now and then, someone shows up in an email marketing or deliverability forum or chat room, trying to make the case that spam is somehow allowed. The argument usually goes like this: "The mailbox providers don't actually require permission, so it's fine if I just send email to whoever I want." After all, other people are sending spam. I'm receiving spam, so spam must be a normalized and expected practice, right?| Spam Resource: All Things Deliverability
Google has very recently added new diagnostic details to its DMARC aggregate reports, and they're a big help for troubleshooting. Instead of digging through scattered email logs across your various email sending platforms and marketing clouds, you can now see specific compliance and authentication-related SMTP error codes right in the DMARC XML reporting! That means when your mail fails Google's sender requirements, you'll know if it was SPF, DKIM, alignment, TLS, PTR/DNS, or even RFC complia...| Spam Resource: All Things Deliverability
Here's a cool tool that a colleague at Valimail created recently, and if you care about protecting against people spoofing your emails through lookalike domains, I think you might find it interesting.| Spam Resource: All Things Deliverability
It's so very 1982. It's electro, funk, and freestyle. It's got an 808. It's got a beat from a leftover, unused track, from prior production sessions for an Afrika Bambaataa album. It stands alone, well, as a groove that gets you on the dance floor, and somebody new samples it every few years. | Spam Resource: All Things Deliverability
I've been thinking about the intersection of A.I. and email, especially in the context of spam filtering, sender reputation, and authentication. Why? Because people ask about it a lot. People really want to know how A.I. will impact their business model, their marketing efforts.| Spam Resource: All Things Deliverability

The email render test space is potentially shrinking a bit, after Litmus having been acquired by Validity earlier this year, and a few folks have asked me if I knew of any other vendors in this space.The main players in that "render testing" space, in my best recollection, have always been Litmus, Email on Acid, and also, Inbox Monster. And Validity itself. So those are the primary platforms/vendors that provide email render testing, and I know lots of folks that use each of them.

The transition is complete, according to my little widget!

Groups.io is a provider of email discussion group hosting that has been around a good long while (launched in 2014) and serves up rather a lot of email. That gives them insight into delivery delays and connection problems relating to internet service providers and mailbox providers both big and small -- the places where their users and those users' community members host their own mailboxes, and from where they communicate with each other, using the platform and tools provided by Groups.io.Th...| Spam Resource: All Things Deliverability
I'm a strong advocate for double opt-in, a very specific email and permission verification process. The process works by, upon receiving an email address in a signup form, sending a confirmation email out to the address, and not considering the person a subscriber unless they positively respond to the email message. (Find more detail on that here.)| Spam Resource: All Things Deliverability
Today on DELIVTERMS, the series here on Spam Resource where we help decode email and deliverability terminology, we're digging into something that's absolutely everywhere in DNS but rarely explained in plain language: TTL. It stands for "Time To Live." And in DNS, it determines how long a piece of information should be considered valid and kept around in cache.| Spam Resource: All Things Deliverability
