Thoughts on Gmail filtering

Gmail has some extremely complex filters. They’re machine learning based and measure hundreds of things about incoming mail. The filters are continually adjusting to changes and updating how they treat specific mail. One consequence of continually adjusting machine learning filters is that filtering is not static.

Delivery and engagement

Tomorrow is the webinar Mythbusters: Deliverability vs. Engagement. This webinar brings together the ISP speakers from EEC15, plus Matt from Comcast, to expand on their comments.

thirty.years.com

Thirty years ago this Sunday, symbolics.com was registered – the first .com domain. It was followed, within a few months, by bbn.com, think.com, mcc.com and dec.com. Symbolics made lisp machines – symbolics.com is now owned by a domain speculator. BBN is a technology R&D company who’ve worked on everything. If I had to pick one […]
