It’s the email time of year…

it’s-the-email-time-of-year…

I’m basically waiting for the various ESPs to announce Just How Much Mail they’ve sent over the last 4 days. Early information from one ESP shows a hefty percentage over the amount they sent last year, and that amount had many, many, many zeros in it. In terms of best practices and ongoing advice: you can never put too many lights on a Christmas tree.

They took the ESP compliance notification email and changed a couple of the links to…

Mentally modelling filters

mentally-modelling-filters

When we talk about filters, we often think there is one filter. But, in many cases there are multiple stages of filters, each examining mail in a different way. In deliverability terms the easiest filters to ignore are the individual user filters. Mostly because there’s nothing we can do about those. These are the baysean style filters built into a lot of email clients as…
