SendHeron
marketing
SendHeron is lifecycle and transactional email for software products. Paste your website URL: it proposes the tags your app should emit, then drafts the full lifecycle suite in your brand voice (welcome, trial, win-back, cancel-save). You read every draft and activate what you want. Visual sequences, templates as blocks or HTML, a REST API with an SDK written for AI agents, several products on one subscription. From €19/month, 7-day trial, card required. EU company, data stored in Europe.

What to expect from an ideal product
- SendHeron drafts your entire email flow from your website URL, so you start reviewing real copy instead of writing from a blank page.
- Every sequence stays in a draft state until you manually approve it, which means nothing reaches your users before you read and edit each line.
- You can adjust subject lines, body copy, and timing directly inside SendHeron without touching a developer or a JSON file.
- All data stays on EU servers, so teams with GDPR obligations can review and activate flows without routing user data outside Europe.
- Once you approve a sequence, SendHeron moves it to production instantly, cutting the gap between editing and sending to near zero.
