SavvyCal vs Resend
Side-by-side trajectory, velocity, and editorial themes.
SavvyCal keeps polishing scheduling ergonomics on a slow, steady cadence.
SavvyCal is a scheduling tool competing on booking-experience quality. Its changelog moves at a measured pace — roughly one release a month — and the recent run is a series of contained refinements: duplicating workflows, locking links against last-minute changes, per-event buffer control, multi-language booking pages, and improvements to booking on behalf of others.
The through-line is control and convenience for the host and for assistants who schedule for others: workflow reuse, guardrails on rescheduling, richer contact records, and localized booking pages. Nothing here shifts the product's category; it is deliberate incrementalism aimed at making the existing scheduling surface more flexible and reliable.
Expect more of the same — small, self-contained booking and workflow refinements on a monthly rhythm — absent any signal of a larger platform or AI move in these entries.
Resend goes agent-native with a hosted, OAuth-backed MCP server for email.
Resend is a developer-first email API that has spent the last quarter widening on two fronts. It is building an agent-native surface — an official Claude Code plugin, mentions in AI chats, and now a hosted MCP server — while also creeping past transactional email into audience tooling with CSV contact import, in-email charts, and richer editor previews. The core remains a clean API for sending mail.
The direction is Resend-as-infrastructure that both humans and agents call directly. The MCP thread — a plugin in May, a hosted server in July — turns email into a tool an LLM can invoke over OAuth rather than hand-rolled keys, while the contacts and broadcast work points at competing with marketing-email incumbents, not just transactional senders. Distribution is shifting toward embedding where developers already are, via Vercel's marketplace and Auth0.
Expect the MCP surface to grow from sending into contact and analytics operations, and the audience and broadcast side to keep maturing toward a full marketing-email offering.
