# Envello

> Transactional email API with EU data residency, a 24-month price-stability pledge, and long log retention (7 days on the free tier, up to 365 days on paid plans).

Envello is a solo-founder, bootstrapped company (not VC-backed). The API is live: account signup, domain verification (SPF/DKIM/DMARC), single and batch sending, delivery/open/click webhooks, suppression handling, and API-key management are all implemented and in production, not placeholder routes. Some backlog items described in the company's public planning docs are still unbuilt; treat only what's linked below as shipped.
