A discussion regarding inconsistent email delivery reveals that many subscribers are not receiving newsletters due to aggressive spam filters from Gmail and Outlook. Large email providers often require "bribes" or high fees from services like MailChimp to guarantee delivery.

Despite the hype, current sex robot technology is described as "cringeworthy" due to rubbery facial movements and unrealistic speech. Comparisons are made to Disney's superior but still imperfect animatronics. A humorous suggestion is made that a truly useful AI doll would be one that could filter emails rather than provide sexual services.

The No Agenda newsletter experienced significant delivery failures despite being sent through MailChimp. Many subscribers, including those running private email servers without filters, reported never receiving the transmission. The hosts investigate whether the issue stems from ISP-level blocking or a failure within the MailChimp platform itself.

AT&T wins a $3 billion government contract for "Einstein 3A," an enhanced cybersecurity service for .gov websites. The hosts express outrage that the multi-billion dollar project appears to consist of basic email filtering and "sinkholing" features that are already available in open-source software. They characterize the contract as a massive waste of taxpayer money for "installing Norton" on government servers.

### Gmail Spam Filters and Newsletter Open Rates

- **Transcript:** https://search.noagendashow.net/episode/742-a-q-in-the-maghrim/chapter/gmail-spam-filters-and-newsletter-open-rates.md

A decline in newsletter open rates is attributed to changes in Gmail and Hotmail spam filtering algorithms implemented around July 4th. The hosts speculate that using bulleted lists in emails triggers spam flags, resulting in a 20% drop in engagement. They recommend using independent email providers like Mark Burkell's service to avoid the restrictions of centralized systems.

- **Transcript:** https://search.noagendashow.net/episode/740-losers-to-lions/chapter/gmail-spam-filtering-newsletter-open-rates.md

Low open rates for the No Agenda newsletter suggest that Gmail and Hotmail have implemented more aggressive spam filtering. Speculation arises that Google changed its algorithms, affecting mailing lists and independent servers. The hosts contrast the filtering of their newsletter with the abundance of commercial spam from retailers like Neiman Marcus and Motley Fool that successfully reaches the primary inbox.

The hosts identify the ".science" top-level domain (TLD) as a primary source of internet spam.

Technical difficulties with the No Agenda newsletter are attributed to Google's aggressive spam filtering and "promotions" tab logic.
