What is ContentStudio?
ContentStudio is bolting ad reporting and AI video generation onto a publishing tool.
The product now covers three jobs that used to be separate purchases: scheduling with multi-level approvals, ad-performance reporting for Meta and Google, and AI media generation inside AI Studio. The last month leans hardest on generation, adding a newer video model, a talking-avatar tool, and a consolidated Brand Profile that feeds both. The Inbox API is the first sign these surfaces are meant to be driven programmatically rather than only clicked.
What is GMass?
GMass is betting its next decade on tracking that doesn't lie and links that don't look like spam.
GMass is a ten-year-old Gmail-native mass-email tool whose recent product work clusters tightly around measurement integrity and deliverability. The last year shipped open-tracking hardening to kill false opens from viewing your own sent mail, an AI template builder that composes HTML layouts inside Gmail, per-recipient time-zone sending, and now friendly click-tracking links. A January 2026 pricing restructure landed alongside a milestone of roughly nine billion emails sent by its users.

ContentStudio is bolting ad reporting and AI video generation onto a publishing tool.
◆ Current state
The product now covers three jobs that used to be separate purchases: scheduling with multi-level approvals, ad-performance reporting for Meta and Google, and AI media generation inside AI Studio. The last month leans hardest on generation, adding a newer video model, a talking-avatar tool, and a consolidated Brand Profile that feeds both. The Inbox API is the first sign these surfaces are meant to be driven programmatically rather than only clicked.
◆ Where it's heading
Two expansions run in parallel. The Meta and Google ad-analytics modules landed eight days apart and share an identical shape, which reads as one template applied per network rather than two separate builds, so more networks are the cheap next step. AI Studio moves on a similar cadence, absorbing whichever third-party video model is current instead of building generation itself.
◆ Prediction
Expect another ad-analytics module on the same template for a remaining network such as LinkedIn or TikTok, and more of the dashboard exposed over the API now that the Inbox has been.
GMass
6.3MARKETING
GMass is betting its next decade on tracking that doesn't lie and links that don't look like spam.
◆ Current state
GMass is a ten-year-old Gmail-native mass-email tool whose recent product work clusters tightly around measurement integrity and deliverability. The last year shipped open-tracking hardening to kill false opens from viewing your own sent mail, an AI template builder that composes HTML layouts inside Gmail, per-recipient time-zone sending, and now friendly click-tracking links. A January 2026 pricing restructure landed alongside a milestone of roughly nine billion emails sent by its users.
◆ Where it's heading
The product is converging on a single argument: that the numbers other email platforms report are wrong, and GMass's are not. Open-tracking hardening attacked inflated open rates; friendly click-tracking links attack the redirect URLs that make tracked mail look like spam to filters and recipients alike. Around that core, the surface keeps widening inside Gmail itself, with composition, scheduling, and reply-handling all pulled into the sidebar rather than a separate app.
◆ Prediction
The clear next step is applying the same treatment to the remaining tracking primitives, most likely custom or per-domain tracking configuration that lets senders keep click data without borrowing a shared redirect domain. The blog cadence mixes SEO content with releases, so expect the next real launch to arrive quietly amid listicles.
