What it is

Nuntly is a developer-focused email platform for sending and receiving transactional email, replying to messages, and tracking activity through one REST API. It supports single or bulk sends, scheduled or immediate delivery, and messages with or without templates. For inbound email, it provides custom inboxes, stored messages, thread grouping, attachment access, webhooks, and a Reply API. The REST API covers domains, API keys, webhooks, analytics, sending, receiving, and team members; documented SDKs include TypeScript and Java. Webhooks expose delivery, open, click, bounce, complaint, and inbound-message activity, with retries, replay, filtering, payload inspection, and signature verification. Logs are retained for up to 30 days. Nuntly says data is encrypted in transit and at rest, and hosted and processed in Europe by default. Its Free plan requires no card and costs nothing; it allows 3,000 emails monthly, 100 daily, one domain, and one inbox. Starter costs €10 a month and allows up to 10,000 emails monthly. Nuntly is headquartered in Châtillon, France.
