Google has updated the Gmail "Bulk Sender Guidelines" page, and it is now called, "Prevent mail to Gmail users from being blocked or sent to spam." Check it out ! ( Thanks to the smart folks at Postmark for the tip! )

You might notice that in my " 2020: What's next? " post, I didn't mention BIMI . BIMI, aka Brand Indicators for Message Identification, is the new way to specify what logo or brand avatar a sender wants shown alongside their email messages. ( Learn more abou…

Mashable's Alex Perry wrote just the other day that one should never bother to clean out your email inbox. Sort of right, sort of wrong. Me, I'd go crazy if I left 250,000 email messages in my email inbox. His point, though, is that you might as well save everything fo…

Apparently it happens to Seth Godin, too ( click here ). He's got a fix for it, see, but those big meanies at Google won't let him implement it. He's even encouraging you to yell at Google on his behalf. (It turns out, Google is a bit shy about letting third parti…

Here's an article from Mailkit's Jakub Olexa explaining how the ISP landscape is different in Europe. This is useful stuff for US-based senders to learn. That chart is especially insightful. Thanks, Jakub!

Well, the new year is here. (Along with a new blog template and updated ISP deliverability guides .) What do you think will happen in the deliverability realm in 2020? Here are my first thoughts. First, DMARC is finally reaching critical mass. No longer an edge-case security…

Once called Verizon Media Group, but now back to the more familiar name of Yahoo Inc. , you might know them as internet service providers AOL, Yahoo and Verizon. The email platform they all utilize now is, from a sender's perspective, Yahoo! Mail. Here are my five top recom…

I hope everybody survived Black Friday and Cyber Monday! It's still a busy week but when you've got things under control, why not take a break and spend it reading about  how the military made Spam (the food) an iconic American brand , courtesy of Navy Times.

As a follow up to my previous post on domain name choice best practices , here's an additional two cents I wanted to share. Because I get this question all the time -- should I use my ".com" domain for my email program? Or should I register a ".email" do…

Sometimes those of us with a quite-possibly-myopic worldview might assume that outside of North America and Europe, spam regulation doesn't exist. Well, here's an example where Egypt's National Telecom Regulatory Authority filed a complaint against an insecticide c…

The folks behind Yahoo Groups sent out a notice a couple of days ago indicating that they are making changes to Yahoo Groups. They say that these changes are to make Yahoo Groups more email-oriented by removing the ability to participate in Yahoo Groups discussions on the web…

Not that kind--the other kind! From Minneapolis-St. Paul Magazine:  Trendy chefs are celebrating SPAM coast-to-coast, and they’re leaving us in the dust. Chicken-fried spam tacos? I want to try those!

Sure! It's legal. Is it wise? Um....let's skip that point for a moment. Let's start with, "it's legal!" What does "FOIA" mean in this context? Wikipedia to the rescue:   The Freedom of Information Act (FOIA), 5 U.S.C. § 552, is a federal…

Tulsi Gabbard's presidential campaign is suing Google for various reasons, primarily for suspending her Google Adwords account. Not really email related, so not really my realm to cover. But something did catch my eye when  Laura Atkins blogged about it last week on Word to…

If you're going to use your domain (or a custom domain) with an email platform, try, if at all possible, to use your main domain name. Here's why I say that. Let's pretend I'm a large multi-national corporation called Al Iverson. I own aliverson.com. Nobody e…

Another anti-spam blacklist has ceased to exist. For more on the now-defunct Email Basura blacklist, head over to DNSBL Resource .

I've updated the XNND DNS lookup tool so that it you can now select "Multi DNS = yes" and the tool will now make the same DNS query against a number of different public DNS servers all in a row. It'll help you catch issues where you've perhaps updated a …
