Humblesend is an email platform being built by Illumetric Technologies AB to bring marketing and transactional email into one focused workspace. Its guiding promise is “Beautiful emails. Serious delivery,” combining an approachable authoring experience with tools for managing sending and protecting reputation.

The platform’s editor is designed for responsive emails, using reliable content blocks, inline editing, reusable styles, autosave, version history, and desktop and mobile previews. Teams can also create plain-text output and work from templates. For audience management, Humblesend aims to make consent, preferences, lists, suppressions, and engagement visible in a traceable customer timeline, with clear unsubscribe handling.

Marketing and transactional messages are kept separate through distinct queues, controls, reputation management, and reporting. Deliverability features include sending-domain verification, DKIM and SPF alignment, DMARC visibility, bounce and complaint suppression, and tenant-aware sending limits. Developers are offered typed API requests, idempotent sending, inspectable and replayable webhooks, scoped keys, and delivery logs. Humblesend describes itself as being built carefully, with its first product shell available to explore and sending still forthcoming.
