A frequent question in a number of deliverability spaces is how to tell if a message is transactional or marketing. In most cases the decision is related to whether or not to respect an unsubscribe request. All too often companies decide that their messages are too important to allow someone to opt-out of. The problem is, in some cases, there is no longer a customer relationship to send notices...
An open is not permission
A decade or so ago I was helping a client troubleshoot a Spamhaus listing. They, as many companies do, had a database with addresses from a number of different sources. Spamhaus was asking for them to reconfirm the entire database, which they didn’t want to do. I came up with the idea that if we had some sign of activity on the email address, like an open or a click and some other...
d= for data
A few ISPs use the d= value in the DKIM signature as a way to provide FBL and reputation data to senders. This has some good bits, in that senders can get FBLs and other information regardless of the IP address they’re using and whether or not they have sole access to it. There are also some challenges with using the d= as a data identifier. One of them is that ESPs may not be able to get a...
Link tracking redirectors
Almost every bulk mail sent includes some sort of instrumentation to track which users click on which links and when. That’s usually done by the ESP rewriting links in the content so they point at the ESP’s tracking server, and include information about the customer, campaign and recipient. The recipient clicks on the link in the email, their web browser fetches the link from the...
New laptop, old reminder
I have a new laptop.
New OS (maybe this year will be the year of Linux on the Desktop?). New hardware problems. New applications. New keyboard layout.
New mail client.
It reminded me of another reason why you want to keep the email address in your From: consistent – it’s something some users will use to automatically load images, which is something you probably want.
Low bounce rates don’t mean a list is good
Many people believe that if they remove non-existent addresses from their mailing lists that their lists will make it to the inbox without a problem. In fact, an entire industry has grown up around the idea that sending mail to valid addresses can never be spam. This isn’t true, of course, spammers use many of the same techniques legitimate mailers do to clean their lists. I don’t...
Delivery is not dependent on authentication
All too often folks come to me with delivery problems and lead off with all of the things they’ve done to send mail right. They assure me they’re using SPF and DKIM and DMARC and they can’t understand why things are bad. There is this pervasive belief that if you do all the technical things right then you will reach the inbox. Getting the technical bits right is an important...
Economics of spam
There was a discussion on Slack about the economics of email. It’s probably not a surprise that I have opinions (Who owns the inbox? Ownership of the Inbox). There was a discussion about this that was useful enough I’d share it. Participants: Laura: Laura Atkins (me!)Steve: Steve Atkins (other half of WttW)Matt V: Director Privacy @ 250ok Laura: Direct mail to your home the owner...
It’s not marketing, it’s spam
There are times when I hesitate to call what marketers do “spam.” I can use the euphemisms with the best of ’em. “Cold emails” “Targeted Marketing” “B2B marketing.” I’ll say it here and now: cold emails are spam. Sales people who are sending enough email that they require automation to actually send the mail are spamming. Look at this...
Re-adding subscribers after reputation repair
A comment came in on Engagement and Deliverability and I thought it was a good question and deserved a discussion. Good article. My question about Gmail engagement is how would I reach someone who has not been opening my emails? Say I want to do a re-engagement campaign. If I temporarily suppress a contact from my list for a period of time and only send to my engaged contacts, will that contact...
