Sulu vs SalesBlink: at a glance
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.
What is SalesBlink?
Cold-email tooling that wants you to skip its own dashboard.
SalesBlink runs cold email sequences — sending, deliverability, replies, and booking. The past few months added an agent layer on top of that: an MCP server in April, an OpenClaw integration in May for autonomous outreach, and in July an AI Copilot inside the dashboard that creates and manages sequences from a prompt. The conventional product kept moving in parallel — a rebuilt meeting scheduler with whitelabel support, email security gateway detection that skips leads whose employers block cold mail, and a July roundup whose headline item is reply detection dropping from hours to seconds.
Sulu vs SalesBlink: editorial side-by-side
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.
SalesBlink
6.3MKT AUTO
Cold-email tooling that wants you to skip its own dashboard.
◆ Current state
SalesBlink runs cold email sequences — sending, deliverability, replies, and booking. The past few months added an agent layer on top of that: an MCP server in April, an OpenClaw integration in May for autonomous outreach, and in July an AI Copilot inside the dashboard that creates and manages sequences from a prompt. The conventional product kept moving in parallel — a rebuilt meeting scheduler with whitelabel support, email security gateway detection that skips leads whose employers block cold mail, and a July roundup whose headline item is reply detection dropping from hours to seconds.
◆ Where it's heading
Two threads, and they point the same way. The deliverability work treats sending capacity as the scarce resource — detecting gateways that would swallow the message, testing inbox placement, selling pre-configured mailboxes with DNS and DMARC handled — so that no send is wasted. The agent work attacks the other cost, the operator's time in the interface. Announcing an MCP server with "ditch the dashboard" and then shipping a Copilot inside the dashboard is the same bet placed twice: sequences described rather than assembled.
◆ Prediction
The AI credits framing that arrived with the Copilot is the thing to watch — a usage-metered agent sitting on top of a seat-priced outreach tool is a pricing question the entries raise but do not settle.
