In an earlier post, I mused about finding the list of IP addresses that bulk emailer Constant Contact uses to send out their email messages. So today, I went looking.
Among the first results is an article with the title ‘The Battle of the Inbox’ on the Constant Contact site that talks about how to get around those pesky people and companies who don’t want their inbox attacked every time a Constant Contact customer has the urge to send out some earth-shatteringly important missive about a new way for them to get at your money.
No IP ranges listed there, though. So I kept looking and lo and behold, the St. Lawrence Seaway is one of several places to find the answer. Ironically, it’s part of a post on the Seaway site about how to get those pesky systems administrators who do their best to keep your inbox safe to let let down the barriers so that Constant Contact’s digital warriors can get through and, I presume, win the battle.
The list is often part of a form letter – there are various examples online – created by Constant Contact to send to system administrators who are blocking Constant Contact emails from entering their networks.
At any rate, here are the ranges:
IP Range: 22.214.171.124 – 126.96.36.199
Network/Netmask: 188.8.131.52 255.255.255.0
Specific IPs sending from this range:
And here’s another list of possible legacy email sources:
Your system administrator could use a list like this to reject email from the computers / computer networks at those IP addresses.
I’ve heard from Constant Contact who offered a briefing with their head of compliance. I’m hoping for mid February.
Some organizations use the company’s services for content that recipients requested and actually want. In my experience, the majority of sources of Constant Contact email parachuting into our inboxes didn’t fit into that category.
The dilemma facing system administrators is this: if I let one Constant Contact customer to send mail into my network, then I’m opening the door to all current and future Constant Contact customers.
The company admits a lot of customers tend to let marketing enthusiasm overcome their adherence the rules of war, even offering extensive educational materials about email etiquette and legal requirements, should they care to read it.
With most of us moving to mobile, unwanted junk landing in our inboxes is becoming more expensive. Bulk email marketers seem either blissfully unaware or willfully blind to the fact that unwanted junk mail sent to mobile devices is being paid for by the recipient as part of their data plan.
Imagine if the junk flyers dumped into your physical mailbox came with a Postage Due notice from the Post Office. If that’s wrong, why should it be okay to shift the cost of digital advertising onto the recipient’s mobile phone bill?
