Misdirected email


While this does seem to be more common with gmail addresses, it’s not solely limited to gmail. I’ve written about this frequently.

There are a lot of cases we hear about where personal information is leaked through misdirected email. Consider how often it happens and no one hears about it.
For marketers, the biggest risk with misdirected email is sending spam to someone who can get that mail blocked by an ISP, major spamfiltering company or blocklist. For companies using email addresses as primary keys for customer databases, the risk is exposing customer information to the wrong people.
I get that address verification is hard. I get it is friction in the signup process. But that shouldn’t really matter when you’re discussing PII.

Growing your list carefully

Karl Murray wrote a great set of recommendations for growing an email marketing list. I really can’t think of anything I would have said differently. Touching customers and getting contact information from them is great, but there are situations where this gets bad addresses. Too many bad addresses can impact delivery.
So how do you grow your list without falling into a delivery trap? The specific recommendations, as always, depend on your specific situation. But knowing how bad addresses get onto your list will allow you to implement mitigation strategies that actually work.

Sending mail to the wrong person, part eleventy

Another person has written another blog post talking about their experiences with an email address a lot of people add to mailing lists without actually owning the email address. In this case the address isn’t a person’s name, but is rather just what happens when you type across rows on they keyboard.
These are similar suggestions to those I (and others) have made in the past. It all boils down to allow people who never signed up for your list, even if someone gave you their email address, to tell you ‘This isn’t me.” A simple link in the mail, and a process to stop all mail to that address (and confirm it is true if someone tries to give it to you again), will stop a lot of unwanted and unasked for email.

Gmail says no expectation of privacy, kinda.

Consumer Watch put out a press release yesterday about a court filing made by Gmail that says Gmail users have no expectation of privacy. I pulled a bunch of the docs yesterday, but have had no real time to read or digest them.
For recap users everything I pulled (and stuff other people have pulled) are available at Archive.org.
The initial complaint was filed under seal at the request of Google. The redacted complaint doesn’t tell us a lot, but it’s available for people to read if they’re interested.
The doc everyone is talking about is Google’s Motion to Dismiss. Everyone is up in arms about Google saying, in that filing, “a person has no legitimate expectation of privacy in information he voluntarily turns over to third parties.” (page 28, line 9). What no one seems to have mentioned is that this is actually a quote from a case that Google is referencing. The whole paragraph may lead one to a different conclusion.
