What is Merge?
Merge grinds weekly connector reliability while edging toward agent-facing tooling
Merge's unified API ships on a weekly cadence dominated by connector maintenance: mapping fixes, pagination and auth hardening, and object-URL coverage spread across Accounting, ATS, CRM, File Storage, and HRIS. Recent weeks add breadth without reshaping the surface, such as Dropbox file-content download and more reliable SharePoint sync for sub-drive accounts. The directional moves sit just behind this window: an Oracle Fusion Cloud ERP beta and a Merge Agent Handler that wires coding agents into Merge via AGENTS.md.
What is Resend?
Resend keeps widening from a raw email API into agent-native tooling and audience management.
Resend remains a developer-first email platform, but its recent surface area is splitting in two directions. One track is agent-native access — an MCP server, a CLI built for humans and AI agents, a Claude Code plugin, and AI-assisted authoring. The other is audience and content tooling — bulk CSV contact import, in-email charts, and richer broadcast composition — pushing it past pure transactional sending.

Merge grinds weekly connector reliability while edging toward agent-facing tooling
◆ Current state
Merge's unified API ships on a weekly cadence dominated by connector maintenance: mapping fixes, pagination and auth hardening, and object-URL coverage spread across Accounting, ATS, CRM, File Storage, and HRIS. Recent weeks add breadth without reshaping the surface, such as Dropbox file-content download and more reliable SharePoint sync for sub-drive accounts. The directional moves sit just behind this window: an Oracle Fusion Cloud ERP beta and a Merge Agent Handler that wires coding agents into Merge via AGENTS.md.
◆ Where it's heading
The release log reads as table-stakes reliability work that keeps Merge's breadth defensible rather than expanding it. Two threads point forward: deeper ERP coverage via the Oracle Fusion beta, and a turn toward agent-facing tooling through the Agent Handler's guided setup for Claude Code, Cursor, and other AGENTS.md-aware agents. The weekly entries themselves remain maintenance-heavy across every category.
◆ Prediction
Expect Oracle Fusion Cloud ERP to move from beta toward general availability and the Agent Handler to accumulate more setup and tooling polish, while weekly releases stay reliability-dominated.

Resend keeps widening from a raw email API into agent-native tooling and audience management.
◆ Current state
Resend remains a developer-first email platform, but its recent surface area is splitting in two directions. One track is agent-native access — an MCP server, a CLI built for humans and AI agents, a Claude Code plugin, and AI-assisted authoring. The other is audience and content tooling — bulk CSV contact import, in-email charts, and richer broadcast composition — pushing it past pure transactional sending.
◆ Where it's heading
The pattern across these releases is Resend trying to own both ends of the email stack: the programmatic API developers integrate, and the audience layer that marketing tools like Mailchimp and Loops occupy. The agent-native investments suggest it expects a growing share of email to be triggered and composed by AI tools rather than hand-written code. Contact import at scale is the clearest sign it wants the audience database, not just the send.
◆ Prediction
Expect the audience side to deepen next — segmentation, list management, or analytics on top of the imported contacts — to match the broadcast and authoring features already shipped.
