Marking mail as spam says what?

I wear a number of hats and have a lot of different email addresses. I like to keep the different email addresses separate from each other, “don’t cross the streams” as it were.   Recently I’ve been getting spam to my womenofemail.org address asking about the wordtothewise.com website. I’m not sure where Ms. Catherine Metcalf bought my Women of Email address or...

Who are mimecast?

Mimecast is a filter primarily used by businesses. They’re fairly widely used. In some of the data analysis I’ve done for clients, they’re a top 10 or top 20 filter. Earlier today someone asked on Facebook if mimecast may be blocking emails based on the TLD. The short answer is it’s unlikely. I’ve not seen huge issues with them blocking based on TLD of the domain...

What does mitigation really mean?

It is a regular occurrence that senders ask filters and ISPs for mitigation. But there seems to be some confusion as to what mitigation really means. I regularly hear from senders who seem to think that once they’ve asked for mitigation that they don’t have to worry about filtering or blocking at that ISP for a while. They’re surprised when a few weeks or even days after they...

What kind of mail do filters target?

All to often we think of filters as a linear scale. There’s blocking on one end, and there’s an inbox on the other. Every email falls somewhere on that line. Makes sense, right? Bad mail is blocked, good mail goes to the inbox. The bulk folder exists for mail that’s not bad enough to block, but isn’t good enough to go to the inbox. Once we get to that model, we can think...

Tempo

When we say that you might just be sending too much email and fatiguing or annoying the recipient into unsubscribing or hitting spam, this is the sort of thing we mean. Three emails (to the same email address) in four minutes might be a bit much. If you can’t combine the content you want to send into a single personalized email, maybe spread deliveries out a bit? Or even not send all of it...

Filters evolving

I started writing this blog post while sitting on a conference call with a bunch of senders discussing some industry wide problems folks are having with delivery. Of course the issue of Microsoft comes up. A lot of senders are struggling with reaching the inbox there and no one has any real, clear guidance on how to resolve it. And the MS employees who regularly answer questions and help folks...

Interacting in professional fora

There are a bunch of online communities – mailing lists, Slack channels, etc. – where “people who do email” interact. Some of them are open to anyone to subscribe, some of them are semi-private and require an invitation, others are closed and only available by invitation and yet others are associated with trade associations and only open to their members. Many of them...

Improving Gmail Delivery

Lately I’m hearing a lot of people talk about delivery problems at Gmail. I’ve written quite a bit about Gmail (Another way Gmail is different, Gmail filtering in a nutshell, Poor delivery at Gmail but no where else, Insight into Gmail filtering) over the last year and a half or so. But those articles all focus on different parts of Gmail delivery and it’s probably time for a...

5 steps for addressing deliverability issues

Following on from my reading between the lines post I want to talk a little bit about using the channels. From my perspective the right way to deal with 99% of issues is through the front door. Last week I found myself talking to multiple folks in multiple fora (emailgeeks slack channel, mailop, IRC) about how to resolve blocking issues or questions. All too often, folks come into these spaces...

Filtering by gestalt

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...
