The challenge of Gmail

A lot of my sales inquiries recently are about getting good inbox delivery at Gmail. I’ve mentioned before, I can usually tell when an ISP changes things because they suddenly become the subject of a great many phone calls.
In this case, Gmail seems to have turned up their engagement filters and is sending a lot more mail to the bulk folder. I have also noticed other people are blogging about Gmail delivery problems. Al eventually determined that it was mailings sent from other IPs that were degrading the delivery of his customer’s emails.
Gmail, more than the other major ISPs, seems to not be weighting IP reputation very heavily these days. They’re looking at domain reputation and they’re using all mentions of a domain in that reputation. A lot of senders, some of them spammers, segregate their email streams (acquisition, marketing, transactional) across IP addresses in order to stop poorly performing mails from harming delivery of other emails they’re sending. But Gmail’s current filtering scheme seems designed to focus on domain reputation and minimize the impact of IP reputation.
This is making the Gmail inbox tough to reach for a lot of mailers these days. Even in cases where the mailer isn’t hiring affiliates or actively partitioning mail, if a domain is seen frequently in spam then delivery for that whole domain is hurting. Signing with DKIM and publishing a DMARC record may help. But the reality right now is that there doesn’t seem to be a silver bullet into the Gmail inbox.

Email marketing OF THE FUTURE!

ISPs are continually developing tools for their users. Some of the newer tools are automatic filters that help users organize the volumes of mail they’re getting. Gmail released Priority Inbox over a year ago. Hotmail announced new filters as part of Wave 5 back in October.
All of these announcements cause much consternation in the email marketing industry. Just today there was a long discussion on the Only Influencers list about the new Hotmail filtering. There was even some discussion about why the ISPs were doing this.
I think it’s pretty simple why they’re creating new tools: users are asking for them. The core of these new filters is ISPs reacting to consumer demand. They wouldn’t put the energy into development if their users didn’t want it. And many users do and will use priority inbox or the new Hotmail filtering.
Some people are concerned that marketing email will be less effective if mail is not in the inbox.

How long is your DKIM key?

While we were at M3AAWG, Wired published an article talking about how simple it was to crack DKIM keys. I didn’t post about it at the time because it didn’t really seem like news. DKIM keys smaller than 1024 are vulnerable and not secure and the DKIM spec does not recommend using keys smaller than 1024. When I asked the DKIM-people-who-would-know they did tell me that the news was that the keys had been cracked and used in the wild to spoof email.
Fair enough.
If you are signing with DKIM, use a key 1024 or longer. Anything shorter and your risk having the key cracked and your mail fraudulently signed.
This morning M3AAWG published recommendations on keeping DKIM keys secure.

Internet fraud and private whois records

The Verge has a long article about Internet Marketing and how much fraud is perpetrated by people who label themselves Internet Marketers.
It was interesting, but I didn’t think it was necessarily relevant to email marketers until I saw this quote from Roberto Anguizola at the FTC Bureau of Consumer Protection.
