Email address validation

One thing anyone collecting email addresses anywhere has to think about is address validation. How do you prevent users from typing bad addresses into your forms? I ran into this yesterday attempting to take an online quiz. Before I was allowed to take the quiz, I had to provide my name, phone number and email […]

The secret to dealing with ISPs

What is the secret to dealing with ISPs? The short answer is: Don’t do it if at all possible. Talking to ISP reps generally isn’t going to magically improve your reptuation.  There is no place in the reputation systems where delivery can be modified because the delivery specialist knows or is liked by the postmaster […]

DKIM: what it’s not

An ESP twittered this past week about their new DKIM implementation going live. They were quite happy with themselves. Unfortunately, in their blog post, they mentioned 3 things that DKIM would provide for their customers, and got it wrong on all 3 points. Their confusion is something that a lot of people seem to get […]

How reputation and content interact

Recently, one of my clients had a new employee make a mistake and ended up sending newsletters to people in their database that had not subscribed to those particular newsletters. This resulted in their recipients getting 3 extra emails from them. These things happen, people fat-finger database queries or aren’t as careful with segmentation as […]

Delivery emergencies

There is no such thing as a delivery emergency. They just do not happen. Delivery is fluid, delivery is changing, delivery is complex. But when delivery goes bad it is not an emergency. There is no need to call up an ISP person at home on a Saturday afternoon and ask them to remove the […]

Technology does not trump policy when it comes to delivery

Recently Ken Magill wrote an article looking at how an ESP was attempting to sell him services based on the ESPs ‘high deliverability rates.’ I commented that Ken was right, and I still think he is. Ken has a followup article today. In the first part he thanks Matt Blumberg from Return Path for posting […]

Compliance vs. Deliverability

Most people I know handling delivery issues for senders have some version of delivery or deliverability in their job title. But as I talk to them about what they do on a daily basis, their role is as much policy enforcement and compliance as it is delivery. Sure, what they’re telling customers and clients is […]

Hidden cost of email blasts

Seth Godin has a post up today talking about how friction, that is the cost of sending marketing, is good for marketing. With more friction, marketers make choices about sending instead of sending to everyone. The post touches on a point I’ve certainly tried to explain to clients and senders in general. Email, of course, […]

    Lots of reports today of a security problem at AOL where accounts are sending spam, or are being spoofed in spam runs or something.

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment
