Getting to the Gmail inbox in concept is simple: send mail people want to receive. For a well established mail program with warm IPs and domains, getting to the inbox in practice is simple. Gmail uses recipient interaction with email to determine if an email is wanted or not. These interactions are easy when mail is delivered to the inbox, even if the user has tabs enabled. When mail is in the...
One of those $5.00 words I learned in the lab was gestalt. We were studying fetal alcohol syndrome (FAS) and, at the time, there were no consistent measurements or numbers that would drive a diagnosis of FAS. Diagnosis was by gestalt – that is by the patient looking like someone who had FAS. It’s a funny word to say, it’s a funny word to hear. But it’s a useful term to...
Those of you who have seen some of my talks have seen this model of email delivery before. The concept is that there are a host of factors that contribute to the reputation of a particular email, but that at many ISPs the email reputation is only one factor in email delivery. Recipient preferences drive whether an email ends up in the bulk folder or the inbox. The individual recipient preferences...
Dear Laura, Our company has been shopping around for ESPs and most of them want to put us on a shared IP address. I have always heard that senders should get dedicated IPs. Will this hurt our deliverability? Regards, Sharing is Hard Dear Sharing, For a long time, IP reputation was the major factor in identifying good mail from bad mail. Good IPs helped mail get into the inbox. Poor IPs were...
A few weeks ago, I got a call from a potential client. He was all angry and yelling because his ESP had kicked him off for spamming. “Only one person complained!! Do you know him? His name is Name. And I have signup data for him! He opted in! How can they kick me off for one complaint where I have opt-in data? Now they’re talking Spamhaus listings, Spamhaus can’t list me! I have...
Last week I posted a link to an article discussing how Gmail builds defenses to protect their users from malicious mail. One of the things I found very interesting in that article was the discussion about how Gmail deploys many changes at once, to prevent people from figuring out what the change was. Let’s take a look at what Gmail said. Make it hard for attackers to understand your...
A bunch of folks today mentioned they were seeing poor reputation for formerly good reputations on Google Postmaster Tools. I’m seeing a lot of screen shots that look like this one. It looks like something is going on over there that has nothing to do with actual reputation. Could be a reporting bug, could be a filtering problem. I’m not seeing people mention delivery problems, just...
September’s big adventure was our trip to Stockholm, where I gave the keynote address at the APSIS Conference (Look for a wrapup post with beautiful photos of palaces soon!) and had lots of interesting conversations about all things email-related. Now that we’re back, we’re working with clients as they prepare for the holiday mailing season. We wrote a post on why it’s so important to make sure...
You’ve started to notice that your campaigns aren’t working as well as they used to. Your metrics suggest fewer people are clicking through, perhaps because more of your mail is ending up in junk folders. Maybe your outbound queues are bigger than they used to be. You’ve not changed anything – you’re doing what’s worked well for years – and it’s not...
Reputation is calculated based on actions. Send mail people want and like and interact with and get a good reputation. Send mail people don’t want and don’t like and don’t interact with and get a bad reputation. Reputation is not … about who the sender is. … about legitimacy. … about speech. … about message. Reputation is … about sender...
