We’re seeing multiple reports that the Yahoo feedback loop stopped working some time in the past couple of days. If you’re not seeing reports, it’s not just you.
Bad SPF can hurt your reputation
Can a bad SPF record ruin your delivery, even though all your mail still passes SPF? Yes, it can. One of our clients had issues with poor delivery rates to the inbox at gmail and came to us with the theory that it was due to other people using their domain to send spam to gmail. This theory was based on ReturnPath instrumentation showing mail “from” their domain coming from other IP...
Thoughts on Gmail filtering
Gmail has some extremely complex filters. They’re machine learning based and measure hundreds of things about incoming mail. The filters are continually adjusting to changes and updating how they treat specific mail. One consequence of continually adjusting machine learning filters is that filtering is not static. What passes to the inbox now, may not pass in a couple hours. One of the...
We're all targets
Last week, another email provider announced their systems had a security incident. Mandrill’s internal security team detected unusual activity and took the servers offline to investigate. While there’s no sign any data was compromised or servers infiltrated, Mandrill sent an email to their customers explaining the incident was due to a firewall rule change. Email service providers are a...
Recipients need to be able to unsubscribe
The The Canadian Radio-television and Telecommunications Commission (CRTC) announced today that Plentyoffish Media paid a $48,000 fine for CASL violations. According to the CRTC news release, Plentyoffish Media was failing to allow consumers to unsubscribe from mail in compliance with CASL. CASL requires that any commercial electronic email message contain an easy and free unsubscribe mechanism...
When spam filters fail
Spam filters aren’t perfect. They sometimes catch mail they shouldn’t, although it happens less than some people think. They sometimes fail to catch mail they should. One of the reason filters fail to catch mail they should is because some spammers invest a lot of time and energy in figuring out how to get past the filters. This is nothing new, 8 or 9 years ago I was in negotiations...
Thoughts on Hotmail filtering
One of the new bits of information to come out of the EEC15 deliverability discussions is how Hotmail is looking at engagement differently than other webmail providers. Many webmail providers really do look at overall engagement with a mail when making delivery decisions. And this really impacts new subscribers the most. If there is a mailing where a lot of subscribers are engaged, then new...

Mythbusting deliverability and engagement
Yesterday I published an article talking about an engagement webinar hosted by the EEC and DMA. I made a couple predictions about what would be said. ISPs do monitor engagement, even if they do it differently than senders thought. Engagement is important for inbox delivery at some ISPs. Different ISPs have different ways of making inbox decisions. Engagement will matter more in the future. And...
Delivery and engagement
Tomorrow is the webinar Mythbusters: Deliverability vs. Engagement. This webinar brings together the ISP speakers from EEC15, plus Matt from Comcast, to expand on their comments. There’s been some confusion about the impact of engagement on delivery and whether or not senders should care about recipient engagement. My opinion on the matter is well known: recipient engagement drives delivery...
