What is Grain?
Meeting recorder bets on MCP and one-click handoff to Claude and ChatGPT as its primary AI bridge.
Grain is shipping fast across three fronts at once. The newest grab-bag adds meeting-detection notifications, refreshed playlists, and tighter HubSpot sync. A major mid-May release introduced an MCP integration, one-click hand-off of meetings to Claude or ChatGPT, Markdown-formatted transcripts that include participant and prior-context, bulk send-to-AI actions, and Personal API access on the Starter tier. Earlier in the quarter, the desktop app gained a real-time notepad and a redesigned meeting page.
What is SMTP2GO?
SMTP2GO ships real email-API gains - scheduling, throughput, batch sending - amid a steady deliverability-content stream.
SMTP2GO's feed mixes a concrete product update with deliverability education. The headline release adds API capabilities for scheduling, higher throughput, and large-batch sending, and a cPanel automation plugin update clears a blocking authentication issue. The rest is content on unsubscribe rules, compliance, warmup, and deliverability.

Grain
6.3COMMS
Meeting recorder bets on MCP and one-click handoff to Claude and ChatGPT as its primary AI bridge.
◆ Current state
Grain is shipping fast across three fronts at once. The newest grab-bag adds meeting-detection notifications, refreshed playlists, and tighter HubSpot sync. A major mid-May release introduced an MCP integration, one-click hand-off of meetings to Claude or ChatGPT, Markdown-formatted transcripts that include participant and prior-context, bulk send-to-AI actions, and Personal API access on the Starter tier. Earlier in the quarter, the desktop app gained a real-time notepad and a redesigned meeting page.
◆ Where it's heading
Grain is rebuilding itself as the AI-friendly meeting layer rather than a standalone meeting tool. The MCP integration plus the deliberate work on AI-readable transcripts (Markdown, contextual metadata, bulk transport) signal that the product team thinks the user's value is increasingly created inside Claude/ChatGPT, not inside Grain itself. The live-meeting notepad and the API additions point in the same direction — make meeting data easy to extract.
◆ Prediction
Next likely moves are deeper MCP surface area (more action types, write-back into Grain from external agents), agent-driven workflows in HubSpot/Salesforce/Zapier integrations, and continued infrastructure work to make transcripts more queryable.
SMTP2GO
5.0COMMS
SMTP2GO ships real email-API gains - scheduling, throughput, batch sending - amid a steady deliverability-content stream.
◆ Current state
SMTP2GO's feed mixes a concrete product update with deliverability education. The headline release adds API capabilities for scheduling, higher throughput, and large-batch sending, and a cPanel automation plugin update clears a blocking authentication issue. The rest is content on unsubscribe rules, compliance, warmup, and deliverability.
◆ Where it's heading
Product direction is toward scaling high-volume senders - throughput, batching, scheduling, and warmup guidance all point at supporting larger transactional and campaign workloads. The heavy educational cadence reinforces a deliverability-expert brand position.
◆ Prediction
Expect further API and throughput work aimed at high-volume senders, plus continued compliance- and deliverability-focused content as Gmail and Yahoo bulk-sender rules keep tightening.
