phpList vs Sleeknote: 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 Sleeknote?
Sleeknote embedded an AI campaign advisor and added single-click answer collection to its popup toolkit.
Sleeknote shipped two significant features in quick succession: Answer Buttons, which let visitors respond to popup questions with a single click (synced directly to connected email platforms), and Sidenote, an AI chat agent embedded in the dashboard that answers questions about campaign performance and suggests next steps using the user's own data. Earlier in the year, Learn to Earn launched a new campaign type where visitors complete short educational modules to unlock a discount — a behavioral model meaningfully different from standard lead capture.

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.
Sleeknote
6.3MARKETING
Sleeknote embedded an AI campaign advisor and added single-click answer collection to its popup toolkit.
◆ Current state
Sleeknote shipped two significant features in quick succession: Answer Buttons, which let visitors respond to popup questions with a single click (synced directly to connected email platforms), and Sidenote, an AI chat agent embedded in the dashboard that answers questions about campaign performance and suggests next steps using the user's own data. Earlier in the year, Learn to Earn launched a new campaign type where visitors complete short educational modules to unlock a discount — a behavioral model meaningfully different from standard lead capture.
◆ Where it's heading
Sleeknote is expanding beyond static popups toward a multi-channel engagement platform: web push (March), AI advisors (Sidenote), educational gates (Learn to Earn), and now single-click data collection (Answer Buttons). Each addition raises the floor for what a 'popup tool' is expected to do, and Sidenote in particular signals a move toward AI-assisted campaign management rather than manual optimization. The Scandinavian market focus — Danish-language content, Rule.io integration — is a secondary but consistent signal.
◆ Prediction
Sidenote will expand from advisory into execution — suggesting and then launching campaign variants or adjusting targeting directly. Answer Buttons will likely gain follow-up branching logic to support conditional popup flows based on the answer given.
