About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

useSend is an open-source email sending platform built on Amazon SES, providing transactional email, marketing campaigns, contact management, SMTP, REST APIs, webhooks, and delivery analytics.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Handle transactional email and marketing campaigns in one platform

API and SMTP sending can coexist with contact-based newsletters and product-update campaigns.

Sources: [2][3]

Track deliveries, opens, clicks, and bounces from the dashboard

Delivery events are visible through the dashboard and can be integrated with existing systems through webhooks and scheduling APIs.

Sources: [2][3]

For teams that want a developer-focused email layer while keeping Amazon SES underneath

It fits teams seeking SES economics with a unified UI for APIs, SMTP, campaigns, and contacts.

Sources: [2]

Evaluate beta maturity and external infrastructure dependencies before production use

The README still labels the project beta, and self-hosting requires database, Redis, AWS, and related configuration. Deliverability operations also need independent validation.

Supplemental curator note

useSend provides a Resend/SendGrid-style developer experience on top of Amazon SES with an open dashboard and APIs. The README still describes the project as beta, and self-hosting requires database, Redis, AWS, and related configuration, so production adoption should also evaluate deliverability and operational maturity.
