Thanks to Denis O’Sullivan for again sharing great deliverability insight. This time around it’s an interview with Yahoo Postmaster Lili Crowley, one of the good people who help to try to keep the barbarians from getting through the gate. It’s always good to learn directly from those in charge, to help you keep looking like the good sender that you are.

Having trouble delivering mail to Yahoo? Wondering how that all works? Why does your mail bounce? TS03, TS04, and more? What do you do about it? How do you triage, troubleshoot and address Yahoo (and AOL) deliverability issues? My Kickbox colleague Jennifer Nespola Lantz explains it all here.

Are you seeing this bounce message when trying to send mail to Yahoo subscribers?451 Message temporarily deferred due to unresolvable RFC.5321 from domain; see https://postmaster.yahooinc.com/error-codesAnd you’ve checked and confirmed that your sending domain seems to resolve for you, so you’re wondering, what the heck is going on and what do I do about it? If so, Steve Atkins has got you covered. Over on the Word to the Wise blog, he explains how Yahoo is looking for an SOA record (Start of Authority) in DNS and depending on how your DNS and delegation are configured, you could be misconfigured in a way that most don’t notice, but would fail this check.Click on over to Word to the Wise to learn more. Thank you, Steve, for clearing this up! It’s a tricky one.

Seen this recently? 451 Message temporarily deferred due to unresolvable RFC.5321 from domain; see https://postmaster.yahooinc.com/error-codes This is Yahoo doing some extra work to identify that the 5321.From domain1 of the mail is acceptable to them. Yahoo are going (slightly) beyond what’s required for the return path to be valid in SMTP terms. SMTP just requires that the return path be syntactically valid – i.e., looks like an email address – and that it be deliverable. The basic DNS check you might do would be to check if the right-hand-side of the email address has an MX record2. So for a bounce address of bounces@email.example.com you’d check to see if email.example.com had an MX record. Yahoo want to also check that it looks like a legitimate address in another way, that the organizational domain of the right-hand-side looks legitimate. The organizational domain is what you might think of as a “domain”

Multiple folks have reported via multiple forums today (May 22nd) that Yahoo’s ISP Feedback Loop (called the “Complaint Feedback Loop/CFL”) may not be working properly at the moment. People are reporting either no volume at all for the past few days or greatly reduced volume of spam complaint reports. I am reliably informed that Yahoo is aware of the issue and is working on fixing things. I’ll update this post when I have more information.

Hey, Al! My company has sent approximately 200,000 email messages in the past month to Yahoo! Mail recipients, but we haven’t received even a single complaint back via our ISP Feedback Loop. Is that normal?No, that is not normal! If you’re sending mail en masse, you’re going to get some non-zero number of complaints back. Even if it’s all fantastically opt-in and there’s no chance of somebody getting an unwanted email message, Yahoo’s ISP Feedback Loop, which they call the Complaint Feedback Loop, is always going to faithfully report along any complaints it is given, and that always will include a low number of complaints from people who truly did sign up for the email message. (Keeping in mind that a complaint isn’t what kills your deliverability dead; it’s a high number or high percentage of complaints that does it.)Thus, I suspect something is broken. Probably something on this checklist:You’re not

By Clea Moore, Principal Product ManagerA few weeks ago we launched a major update for Yahoo Mail on iOS and Android . (If you don’t like reading too much, we made a nice video too!) The redesigned apps are the latest in our quest to help our users to save time and money. Key features we offer help with managing digital receipts, gift cards, subscriptions, and packaging tracking, allowing our users to find what they need even faster. With new organizational features that filter consumers’ inboxes, attachments, and even travel itineraries, the updated Yahoo Mail app offers users quick and easy access to the information that matters most while keeping them and their data safe and secure.A lot of these features are made possible through machine learning and our mail intelligence services. But we believe that working together with brands and sending platforms, and offering tools and guidance for how

The email domain love.com was previously owned by AOL, then Verizon, then Yahoo, as the email services and corporate oversight changed for the AOL/Yahoo email services. From the context, it sounds as though it was once possible to have an email address at the love.com domain name — but no longer. Email service for love.com was ended by AOL/Yahoo as of July 31, 2022.It looks as though the domain name love.com was sold to a new company, which was speculated to have netted the domain owner rather a large sum of money.As of October 2022, the domain love.com does currently have an MX record (pointing to Google), but any love.com addresses on a typical marketer’s legacy list is likely going to be from the AOL days and not up to date, so I recommend suppressing those addresses.Please feel free to leave your best “love is dead” jokes in the comments

Check it out — it’s our first taste of BIMI on iOS outside of beta. Apple iOS users who upgrade to iOS 16 can now see a BIMI logo associated with an email send, depending on what mailbox provider they use. All four of these CNN Newsletter signup emails were opened and viewed on the default Apple mail client in iOS 16.0.2, and as you can see, iCloud and Fastmail users get shown the BIMI logo for CNN! You’ll note that no logo is displayed for the Yahoo and Gmail subscribers, even though both platforms support BIMI (and CNN has the Gmail-required VMC in place). Why Fastmail and not Gmail or Yahoo? I suspect that Fastmail was quickest to implement an updated “authentication results” header that includes information about the BIMI logo checks, and I don’t think Gmail and Yahoo are including that information. Yet? It seems likely that they’ll catch
