Increase in Barracuda IP blocks

A number of folks are talking about a significant uptick in Barracuda IP blocks over the last few days. These blocks appear to be affecting wide ranges of IPs across multiple networks.

Raising the standard

Last week news broke that Mailchimp had disconnected a number of anti-vaccination activists from their platform and banned anti-vax content. I applaud their decision and hope other companies will follow their lead in banning harmful content from their network.

Measurements

One of the things I’ve been spending a lot of time thinking about lately is how we measure deliverability. Standard deliverability measurements include: opens, bounces, complaints, and clicks. There are also other tools like probe accounts, panel data, and public blocklists. Taken together these measurements and metrics give us an overall view of how our mail is doing.

End of an era

A few weeks ago, Return Path announced they were being purchased by Validity, who also own BrightVerify. Last week, they had a round of layoffs. According to sources inside the industry, Validity is closing the New York headquarters and Indianapolis offices and layoffs involved more than 170 staff members.

Their network, their rules

Much of the equipment and wires that the internet runs on is privately owned, nor is it a public utility in the traditional sense. The owners of the property have a lot of leeway to do what they like with that property. Yes, there are standards, but the standards are about interoperability. They describe things you have to do in order to exchange traffic with other entities. They do not dictate internal policies or processes.

Apple one time email addresses

At WWDC 2019 Apple announced “Sign in with Apple.” This is a service that allows iOS users to log into different applications with private, dedicated email address. When developers send mail to that address, Apple will forward it to the email address associated with the users AppleID. App developers that offer any third party log in will be required to also offer AppleID log in.

ESPs are failing recipients

Over the last few years I’ve reduced the complaints I send to ESPs about their customers to almost nothing. The only companies I send complaints to are ones where I actually know folks inside the compliance desk, and I almost never expect action, I just send them as professional courtesy.

Google Suspicious Link Warnings

A number of folks in the sender space are reporting intermittent “This link may be suspicious” warnings on their emails. I first heard about it a few weeks ago from some clients. One wasn’t sure what was going on, the other found a bunch of malware uploaded into their customer accounts.

Techdirt lawsuit settled

Back in 2017 Techdirt wrote a series of articles about Shiva Ayyadura. Shiva claims he invented email. (narrator voice: he didn’t). I wrote about the lawsuit when it was dismissed on First Amendment grounds. The parties cross appealed, and have been in settlement talks for 18 months.

What’s up with gmail?

Increasingly over the last few months I’ve been seeing questions from folks struggling with reputation at Gmail and inbox delivery. It seems like everything exploded in the beginning for 2019 and everything changed. I’ve been avoiding blaming it all on TensorFlow, but maybe the addition of the new ML engine really did fundamentally change how things were working at gmail.
