Fonoster
Fonoster parks its Deepgram diarization work after two 0.22.x stability patches.
A side-by-side editorial comparison of Salesmsg and SMTP2GO — release velocity, themes, recent moves, and the top alternatives to consider.
Salesmsg lists its MCP server with Claude and ChatGPT, so texting runs from the assistant.
Salesmsg now has an official MCP server listed in the Anthropic and OpenAI marketplaces, letting Claude, ChatGPT and other MCP clients search and update contacts, send texts, build broadcasts and query account analytics. A week earlier it added inbound call history, AI call scorecards, HubSpot-synced call dispositions and webhook enrollment. The stream combines CRM depth with more autonomy and oversight for its texting and calling agents.
Deliverability blogging with one real API release buried in the run
Most of the feed is deliverability education and comparison content: a scan-to-email setup and troubleshooting guide, a third-party ranking from EmailToolTester, a tested top five of transactional email services, a spam-avoidance playbook, and a definitional piece on transactional email. The exception is June's API release, which added scheduled sending, throughput improvements and more efficient large-batch sending.

The stream combines CRM depth with more autonomy and oversight for its texting and calling agents.
Salesmsg is opening itself up as a set of actions other systems can call, first through webhooks into its own automations and now through general-purpose AI assistants. At the same time its own AI agents are getting more oversight via scorecards and call histories. The product is moving from an SMS inbox toward a messaging backend that both its agents and outside agents operate.
Expect the MCP tools to expand beyond contacts, texts and broadcasts into calling, workflows and surveys. The entries don't show whether MCP use is limited by plan.

The exception is June's API release, which added scheduled sending, throughput improvements and more efficient large-batch sending.
SMTP2GO's product signal arrives roughly once a quarter and always concerns the sending path — scheduling, throughput, batch efficiency — aimed at high-volume senders rather than at the dashboard. Everything between those releases is search-oriented content built around deliverability anxiety, plus independent ranking results used as proof.
On the pattern of the June release, further API work on sending at scale is the most likely next product entry; the intervening posts will stay educational.
