About SocketLabs
SocketLabs leans on platform-positioning content; its recent feed shows messaging, not shipping.
The recent entries are thought-leadership and positioning pieces — deliverability philosophy, 'legacy ESPs are cracking,' and platform deep-dives — plus a note on Yahoo's new sender Insights Dashboard.
