Sendible is steadily hardening publishing reliability and reporting accuracy across networks
Sendible's changelog is genuine product work focused on two areas: making publishing more reliable (rebuilt media infrastructure, universal media validation) and improving cross-network reporting (Facebook Reels analytics, corrected LinkedIn follower data). Recent additions include image alt text for accessibility and a redesigned Unified Calendar for managing drafts, scheduled posts, and queues in one view. The feed shows some duplicate entries for the same feature on different dates.
Single Grain keeps publishing AI sales and marketing how-tos, not product changes.
The Single Grain feed is agency blog content, not a changelog. The November 6 to 9 posts cover AI re-engagement bots for stalled deals, the Anthropic S-1, go-to-market budgets, tracking checks after site migrations, AI image rights, X follower analysis and networking follow-up emails.
Sendible's changelog is genuine product work focused on two areas: making publishing more reliable (rebuilt media infrastructure, universal media validation) and improving cross-network reporting (Facebook Reels analytics, corrected LinkedIn follower data). Recent additions include image alt text for accessibility and a redesigned Unified Calendar for managing drafts, scheduled posts, and queues in one view. The feed shows some duplicate entries for the same feature on different dates.
The direction is operational dependability for social-media managers — fewer failed posts, accurate analytics, and a single workspace for scheduling. Sendible is deepening the core publish-and-measure loop rather than chasing new surfaces. Accessibility (alt text) and unified scheduling suggest attention to workflow polish on top of the reliability foundation.
Expect continued reporting-accuracy work across more networks and further consolidation of the scheduling/calendar experience, with reliability remaining the throughline.
The Single Grain feed is agency blog content, not a changelog. The November 6 to 9 posts cover AI re-engagement bots for stalled deals, the Anthropic S-1, go-to-market budgets, tracking checks after site migrations, AI image rights, X follower analysis and networking follow-up emails.
The editorial mix leans further into AI-assisted sales workflows, with several posts describing bots that draft follow-ups for a rep to approve. None of it describes a shipped product.
The feed will keep producing several posts per batch on AI sales and marketing tactics; nothing in it points to a product launch.
