phpList vs Single Grain: at a glance
What is phpList?
phpList shows renewed 3.7.0 release-candidate activity after a long dormant stretch.
The feed is GitHub release tags, but the entries carry almost no detail — recent ones are just 'Release Candidate N for version 3.7.0.' After a gap stretching back to 2024, two 3.7.0 RCs landed in June 2026, signaling the project is moving toward a 3.7.0 release.
What is Single Grain?
Single Grain's feed is agency blog content on AI search and SEO — no product to track.

phpList vs Single Grain: editorial side-by-side
phpList
5.0MARKETING
phpList shows renewed 3.7.0 release-candidate activity after a long dormant stretch.
◆ Current state
The feed is GitHub release tags, but the entries carry almost no detail — recent ones are just 'Release Candidate N for version 3.7.0.' After a gap stretching back to 2024, two 3.7.0 RCs landed in June 2026, signaling the project is moving toward a 3.7.0 release.
◆ Where it's heading
Development cadence is slow and bursty: a long quiet period followed by RC3 and RC4 within days. The crawl source yields contentless tags, so the substance of 3.7.0 isn't visible here — only that it's progressing through release candidates.
◆ Prediction
Expect a stable 3.7.0 release to follow the RC sequence, though the feed gives no detail on what it contains.
Single Grain
2.5MARKETING
Single Grain's feed is agency blog content on AI search and SEO — no product to track.
◆ Current state
SparkPulse tracks Single Grain's marketing blog, not a software product. Recent posts cluster around one theme — how large language models and AI search reshape SEO, positioning, keywords, and brand recall. These are agency thought-leadership articles, not product releases.
◆ Where it's heading
The only observable arc is editorial: an all-in content bet on 'LLM SEO / AEO' as the successor to classic SEO. There is no product changelog behind this feed, so there's no capability trajectory to read — just where the agency is pointing its content.
◆ Prediction
Insufficient product signal for a product prediction; expect continued blog output on LLM-era search and AI marketing tactics.
