Overusing ISP contacts

I’ve written frequently about personal contacts at ISPs and how the vast majority of delivery problems can be solved without picking up the “Bat Phone” and having someone at the ISP do something. Al touches on the same subject today, blogging about his recent experiences having to contact “Barry” multiple times for many different issues.

My goal going forward is this: I will not reach out to an individual person at an ISP more than once every two months or so, if I can at all help it. If I’m contacting them more than that, then something is broken, and that broken something is probably on my side of things. All of the big ISPs have published processes that work fine for almost any eventuality. That’s why those processes exist, to help people sending mail work through any issues observed.

As I said in my The Secret To Dealing with ISPs post, the vast majority of issues can be handled on the sender side without involvement of anyone at the ISP.

Sending mail from unread email addresses

Some marketers, even large marketing companies, send mail from email addresses that are unread. Justin Premick posted a list of reasons this is a very, very bad idea. Be sure to read the comments, too.

The Weekend Effect

Sending mail only Monday through Friday can cause reputation and delivery problems at some ISPs, even when senders are doing everything right. This “weekend effect” is a consequence of how ISPs measure reputation over time.
Most ISPs calculating complaint rate use a simple calculation. They measure how many “this is spam” clicks a source IP generates in a 24 hour period. Then they divide that number by how many emails were delivered to the inbox in the same 24 hour period.
The weekend effect happens when a sender sends on weekdays and not on the weekend thus lowering the number of emails delivered to the to the inbox. Recipients, however, still read mail on the weekend, and they still hit the “this is spam” button on the email. Even if the number of “this is spam” clicks is lower than a normal weekday, with no incoming email the rate of spam complaints goes above ISP thresholds. Even a very well run mailing program may see spikes in complaint rate on the weekends.
Now, when the ISPs are measuring complaint rates over time, they take the average of the average complaint rates. If the rates spike high enough on the weekend (and they can spike to the 1 – 3% range, even for a well run list), that can hurt the senders’ reputation.
The good news is that ISPs are aware of the weekend effect and take this into account when manually looking at complaints. The bad news is that not all of the major ISPs take this into account when programatically calculating reputation.
There isn’t very much senders can do to combat the weekend effect, except be aware this can happen and may be responsible for poor mailing performances on Monday. If you are seeing delivery problems you think may be a result of the weekend effect you can contact the ISPs and ask for manual review of your reputation. Some ISPs can provide manual mitigation for senders with otherwise clean stats. d

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 at an ISP.
With my clients, I work through delivery issues and can solve 80 – 90% of the issues without ever having to contact anyone at the ISPs. 90% of the remaining issues can be handled using the publicly available contacts and websites provided by the ISPs.
In the remaining cases, the “secret” to getting useful and prompt replies is to:
