Private whois records hide spammers and help bring down a registrar

I’ve talked in the past about how many spam filters, ISPs and blocklists treat domains that are registered behind privacy protection. I’ve written about how many commercial domains behind privacy protection are used for fraud. I’ve written about multiple legal cases where the courts ruled against companies using privacy protected domains in email. I’ve even gone so […]

Do Gmail tabs hurt email marketing?

Earlier this year, Gmail rolled out a new way for users to organize their inbox: tabs. Tabs were an attempt by Gmail to help Gmail users organize their mail, particularly programmatically generated email like social media alerts and marketing mail. While many of us took a wait and see approach, a number of email marketers […]

Hotmail having a bad day

Looks like Hotmail / Microsoft is having a rather bad day. Their DNS seems to be intermittent. While they were down a while ago they were returning SERVFAIL for some DNS lookups, including MX lookups. For senders who have the DNS data in their recursive resolvers, this will have no impact. For senders who either […]

Christine Borgia has a post on the Return Path blog where she interviews a number of different groups (spamfilters, DNSBLs, mailbox providers) about their filtering strategy for the holidays.

Unsubscribing from spam, part 2

Yesterday I posted about why the reasons a lot of people give for not unsubscribing from spam are mostly wrong. Unsubscribing from spam doesn’t seem to confirm your address and it doesn’t seem to increase your spam load. But does that mean you should unsubscribe from spam? I’m not sure about that. I’ve been working […]

One myth that seems to never actually go away is “unsubscribing just confirms you’re a real address and your address will get sold and […]

Feel good Friday

I’ve told myself I can’t stop working until I post. Sadly, I can’t think anything useful to post. It’s been one of those weeks where I had some tricky and complicated client issues to work through. I can think of a lot of things to say, but I don’t want co compromise any client information. […]

Yahoo now auctioning domain names

This summer Yahoo shook up the email ecosystem by publicly announcing they were recycling usernames. The shakeup wasn’t so much that they were recycling usernames, but that they did it in a way that compromised user information and account security. Any user that had an account tied to a recycled Yahoo account is at risk […]

Payday loan mail

Mickey has a great story of what happened when he gave a lead gen company his email address. Over 200 emails in 2 weeks from companies that seem unrelated to the signup company. It’s this behavior by PayDay senders that causes their mail to be filtered and has caused many, many ESPs just to prohibit […]
