Sometimes we have a client who has done something wrong when setting up authentication. Their DKIM signing fails due to something being wrong with the public key they’ve published. The published key looks fine, by eye. It’s got all the fields it should have, but diagnostic tools give inscrutable error messages. If you’re lucky, “This doesn’t seem to be a valid RSA...
There always seems to be appetite from folks to read the tea leaves and follow up with predictions about what the future holds. I mean, how many folks in the US are obsessively refreshing polls for the last few weeks? (American’s: don’t forget to vote on Tuesday!) The reality is, though, we don’t know what the future holds and we can’t always make predictions. I’ve...
I was avoiding commenting on the email open tracking bad take that seems to be going viral round the more gullible corners of LinkedIn.

A non-human-interaction (NHI) open is where some sort of automation fetches the image without human interaction – i.e. it’s fetched when the automation feels like it, not triggered by a user...
If you’re using sendy and you’ve found that RFC 8058 one click unsubscribe fails – or, worse, seems to work but doesn’t actually unsubscribe the user – you should take a look at James’ workaround.
Lots of times I see someone asking a question and they talk about their sending domain. And it’s sometimes not 100% clear which domain they mean by that – and when we’re talking about alignment and reputation it can make a difference. So here’s a list of (some of?) the different places a mailserver uses a domain. Hostnames Machine Hostname: What the operating system...
BIMI is the protocol you can use to publish an icon to display in the inbox of some large consumer webmail providers. To have it displayed at Gmail you need more than just clean DMARC and a published BIMI record, you also need to have a Verified Mark Certificate, a VMC. A VMC is a certificate, very similar in many ways to the TLS certificates used to secure webpages. It’s issued by a...
