MailBeez
MailBeez V5 arrives with a redesigned workspace, dark mode and V5-ready modules.
A side-by-side editorial comparison of OneSignal and Optimove — release velocity, themes, recent moves, and the top alternatives to consider.
OneSignal is moving from measuring sends to measuring whether people came back.
OneSignal's feed is dominated by marketing content — platform comparisons, seasonal playbooks, deliverability explainers — with actual releases collected into a monthly roundup. August's roundup names three areas: new retention metrics, a Journeys API, and protections for sender reputation. The roundup body is a teaser, so the scope of each is not readable from the feed itself.
Optimove gives customers until January to move to its new Data Connections API
Optimove keeps building out its APIs. Data Connections API V2 is rolling out gradually and V1 is deprecated, with a switch-over deadline of 11 January 2027. Earlier this month a bulk endpoint arrived to delete up to 10,000 customer profiles per request; before that the work centred on loyalty and gamification endpoints.

The direction implied is a shift from counting sends to measuring return behavior, plus programmatic access to journeys that were previously assembled in the interface. Both suit a buyer running messaging as infrastructure rather than as campaigns. The surrounding content consistently positions OneSignal against Firebase and other push platforms on AI handling.
With a Journeys API named but not detailed, the next concrete release is likely the SDK or documentation work that makes journeys fully scriptable. The entries do not show enough to say how far the retention metrics reach.

Earlier this month a bulk endpoint arrived to delete up to 10,000 customer profiles per request; before that the work centred on loyalty and gamification endpoints.
After months of additive endpoints, Optimove is now retiring old API versions, which puts work on integrators' calendars. The pattern points to a data layer being consolidated alongside the loyalty features.
Migration guidance and reminders for the V1 sunset are likely before January; the notes do not say what V2 changes, so the size of the migration is unclear.
