What is Litmus?

The blog feed says nothing; Litmus's real changelog sits undated in a separate scrape.

Two sources sit under this product and they do not agree. The dated feed is a deliverability and lifecycle education blog — footers, rebrands, preference centres, birthday sends, holiday prep — and announces no product change; one entry even carries the rebrand article's excerpt instead of its own, a scrape defect. The undated rows are the actual Litmus release archive: Email Guardian, Integrated Insights, Litmus Personalize, Litmus Assistant, and two dozen smaller Builder, Proof, and testing releases.

What is Optimove?

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 blog feed says nothing; Litmus's real changelog sits undated in a separate scrape.

◆ Current state

Two sources sit under this product and they do not agree. The dated feed is a deliverability and lifecycle education blog — footers, rebrands, preference centres, birthday sends, holiday prep — and announces no product change; one entry even carries the rebrand article's excerpt instead of its own, a scrape defect. The undated rows are the actual Litmus release archive: Email Guardian, Integrated Insights, Litmus Personalize, Litmus Assistant, and two dozen smaller Builder, Proof, and testing releases.

◆ Where it's heading

Read from the release archive rather than the blog, Litmus has moved outward from pre-send rendering QA in three directions: analytics that join ESP performance data to its own engagement data, open-time personalization acquired with Kickdynamic, and generative drafting inside the editor. The in-ESP testing integrations — Klaviyo, Adobe Journey Optimizer, Intilery — are the same capability extended market by market. Apple's Mail Privacy Protection forced a run of measurement-integrity work that the later reporting features depend on.

◆ Prediction

Because the archive carries no dates, ordering and recency are unreadable and no confident call on the next release is available from this feed. What can be said is that the analytics and personalization lines each accumulated follow-on releases after their originating launch, so further work on those two surfaces is the pattern the entries support.

Optimove gives customers until January to move to its new Data Connections API

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
