Kit is wiring AI access and audience intelligence onto its creator email core.
A side-by-side editorial comparison of Optimove and MailerLite — release velocity, themes, recent moves, and the top alternatives to consider.
Optimove builds out a developer-extensible loyalty and gamification stack
Optimove's changelog is dominated by its developer hub, and the through-line is loyalty. Over the past month it shipped a full Loyalty System API, added level-claiming and calculated-reward mission endpoints, and published a reference schema for its loyalty and gamification events. Older entries are incremental API documentation and minor response-field additions.
MailerLite is becoming a creator-commerce suite, with AI now reaching into the email editor.
MailerLite is steadily expanding past email into creator monetization — digital products, paid and free bookings, Stripe-backed promotion flows — while modernizing the core authoring experience. The standout this window is a pair of rebuilt editors: a distraction-free Simple editor and a Custom HTML editor with an integrated AI agent that edits HTML from plain-English instructions. Around that, the releases are incremental: new templates, brand-settings reorganization, and richer custom reports.

Older entries are incremental API documentation and minor response-field additions.
Loyalty is becoming a first-class, programmable surface rather than a packaged feature, with customers expected to build their own widget frontends against 20-plus endpoints. The shift from auto-granted to player-claimed level rewards signals a more game-like, engagement-driven model.
Expect further loyalty endpoints and likely webhook or streaming support for the gamification events just documented.

The standout this window is a pair of rebuilt editors: a distraction-free Simple editor and a Custom HTML editor with an integrated AI agent that edits HTML from plain-English instructions. Around that, the releases are incremental: new templates, brand-settings reorganization, and richer custom reports.
The arc points toward an all-in-one platform where a solo creator runs email, a storefront, bookings, and analytics in one place — and increasingly authors content with AI assistance rather than hand-coding. Each release fills a gap in that loop: a way to sell, a way to schedule, a way to measure, a way to write faster. The commerce features and the AI editor are the two threads carrying the most weight.
Expect the AI agent to extend beyond HTML editing into copy generation or campaign assembly, and the commerce stack (products, bookings, Stripe) to gain more automation templates tying purchases to follow-up sequences.
