Terminology

There is a lot more to say here, and I’m working on a longer post to really talk about the underlying racism in tech and how we as an industry have failed. In the deliverability space, specifically, the use of blacklist/whitelist is terminology rooted in racism (black is bad, white is good). Many DNSBLs use […]

Launch your COVID-19-themed marketing email campaign only if you can answer yes to four questions: Am I telling customers something different from other brands versus saying the same thing as everyone else?

The key to improving deliverability

According to the UK DMA, marketers report improvements in deliverability after GDPR went into effect. I mean, thank you UK DMA for doing the research.

Stop obsessing about open rates

In 2020: 250OK says open rates were much lower than ESPs report. The Only Influencers list hosts a discussion about the value and use of open rates.

Bacteria were (mostly) simple: just about every trait was controlled by a single gene. We could study what that gene did by removing […]

Forget about engagement, think inboxing

There are so many cases and ways that a pixel load can be triggered, without the user actually caring about the mail that it’s […]

Opting out of “service” messages

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.

An open is not permission
