What is Resend?

Resend is turning an email API into something other people build products on.

Two months of releases split cleanly. One half is dashboard housekeeping — template folders, suppression management, Open Graph previews in the editor, Message-ID exposed on webhooks for threading. The other half is platform plumbing: a hosted MCP server, OAuth 2.1 with PKCE, a Claude connector, a Codex marketplace plugin, and automatic revocation of API keys leaked to GitHub.

What is rsyslog?

The syslog daemon is quietly becoming an OpenTelemetry-era pipeline, YAML config and all.

rsyslog ships bi-monthly scheduled-stable snapshots of its daily-stable branch, and the last two carried real capability rather than upkeep. April added YAML as an alternative configuration format, an Azure Monitor output, API key authentication for imhttp, and native protobuf encoding for omotel over HTTP. June followed with an Elastic Beats and Lumberjack input, a POSIX FIFO input, experimental TCP stream compression between omfwd and imtcp, and shared per-source ratelimit policy.

Resend is turning an email API into something other people build products on.

◆ Current state

Two months of releases split cleanly. One half is dashboard housekeeping — template folders, suppression management, Open Graph previews in the editor, Message-ID exposed on webhooks for threading. The other half is platform plumbing: a hosted MCP server, OAuth 2.1 with PKCE, a Claude connector, a Codex marketplace plugin, and automatic revocation of API keys leaked to GitHub.

◆ Where it's heading

The center of gravity has moved from features a developer uses to interfaces another product consumes. OAuth is the hinge — with it, third parties can act on a user's Resend account without holding a key, which is the precondition for the connector and plugin distribution Resend is now shipping into Claude, Codex and Cursor. Tracking the 2026-07-28 MCP spec within nine days says they intend to stay current with that surface rather than treat it as a side project.

◆ Prediction

The pattern points to scoped OAuth permissions and a listing surface for third-party Resend apps, plus continued fast-following of MCP spec revisions. Nothing in these entries indicates a pricing or deliverability change.

The syslog daemon is quietly becoming an OpenTelemetry-era pipeline, YAML config and all.

◆ Current state

rsyslog ships bi-monthly scheduled-stable snapshots of its daily-stable branch, and the last two carried real capability rather than upkeep. April added YAML as an alternative configuration format, an Azure Monitor output, API key authentication for imhttp, and native protobuf encoding for omotel over HTTP. June followed with an Elastic Beats and Lumberjack input, a POSIX FIFO input, experimental TCP stream compression between omfwd and imtcp, and shared per-source ratelimit policy.

◆ Where it's heading

Two moves are reshaping what this product is. The configuration story is opening up — RainerScript, rsyslog's bespoke and long-criticized config language, now has a YAML alternative while gaining new helpers of its own. And the transport story is converging on the modern observability stack: native protobuf for OpenTelemetry output, a cloud vendor sink, Beats and Lumberjack ingestion. Underneath both runs continuous defensive hardening across parsers, inputs, outputs, queues and TLS, mentioned in both releases.

◆ Prediction

Expect the YAML configuration path to broaden from alternative to fully supported, and TCP stream compression to move from experimental to stable, since both are flagged as partial in the releases that introduced them.
