AWeber vs Sulu
A side-by-side editorial comparison of AWeber and Sulu — release velocity, themes, recent moves, and the top alternatives to consider.
AWeber vs Sulu: at a glance
What is AWeber?
AWeber keeps moving email marketing out of its own console and into whatever tool you already have open.
The AI builder family now covers signup forms, landing pages, and email, with image editing live in the form builder and rolling out to the others. The landing page builder takes a goal described in plain language and returns headline, layout, images, and copy together. Outside the builders, AWeber is live in Claude's connector directory and the ChatGPT App Marketplace, links are auto-tagged with UTM parameters so email attribution appears in Google Analytics without setup, and sent-message charts plot opens and clicks across up to 100 recent broadcasts.
What is Sulu?
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
Sulu is a Symfony-based CMS for developer-built sites, and its release process is a synchronised pair: every 3.0.x patch ships within a minute of the matching 2.6.x patch, carrying largely the same pull requests. Six releases in five months — 3.0.8/2.6.25, 3.0.7/2.6.24, 3.0.6/2.6.23 — are almost entirely fixes, editor upgrades and framework compatibility work. A security advisory was patched across both branches in March.

AWeber
6.3MKT AUTO
AWeber keeps moving email marketing out of its own console and into whatever tool you already have open.
◆ Current state
The AI builder family now covers signup forms, landing pages, and email, with image editing live in the form builder and rolling out to the others. The landing page builder takes a goal described in plain language and returns headline, layout, images, and copy together. Outside the builders, AWeber is live in Claude's connector directory and the ChatGPT App Marketplace, links are auto-tagged with UTM parameters so email attribution appears in Google Analytics without setup, and sent-message charts plot opens and clicks across up to 100 recent broadcasts.
◆ Where it's heading
Two directions, and they point the same way. Generation keeps widening — each surface a user would previously have built by hand becomes something described in a sentence, with forms first, landing pages next, and image editing spreading across all three. Distribution keeps decentralizing — the assistant connectors let the account be operated from a conversation rather than the console, with drafts saved for review rather than sent. The reporting work fits this too: auto-tagged UTM parameters mean the attribution shows up in a tool the customer already uses instead of requiring a visit to AWeber's own analytics.
◆ Prediction
The connector's surface should widen from broadcasts and subscriber lookups toward the automation and landing-page objects the AI builders already create. Whether AWeber treats chat as a companion to the console or as the primary interface is not something these entries settle.
Sulu
5.0MKT AUTO
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
◆ Current state
Sulu is a Symfony-based CMS for developer-built sites, and its release process is a synchronised pair: every 3.0.x patch ships within a minute of the matching 2.6.x patch, carrying largely the same pull requests. Six releases in five months — 3.0.8/2.6.25, 3.0.7/2.6.24, 3.0.6/2.6.23 — are almost entirely fixes, editor upgrades and framework compatibility work. A security advisory was patched across both branches in March.
◆ Where it's heading
Three threads run through the pairs. Editor upkeep is constant, with CKEditor moving to 47 LTS and then 48 and the fallout — table widgets, webpack font builds — fixed release by release. Framework compatibility is the second: Request->get calls replaced for Symfony 8, PHPUnit 13 and PHPStan kept green on lowest dependencies. The third and most interesting is data-model cleanup on the 3.0 side, where tags migrated from names to IDs behind a newly added DoctrineMigrationsBundle, with smart-content filters reworked to match. What is not visible is any capability that exists on 3.0 and not on 2.6 — a major version that is not yet behaving like one.
◆ Prediction
Expect the paired-release rhythm to continue with more Symfony 8 preparation and CKEditor 48 fallout. The open question is when 3.0 starts receiving work that is not upmerged from 2.6; until then the major version number is not buying users anything.
