Sharing, archiving, drag-and-drop moves, and quick asset creation help if your team already runs many workspaces or shared libraries. The real value is less admin overhead and better reuse; the risk is looser governance if folder permissions and naming rules are inconsistent.\r\n\r\n<b>Email Designer API<\/b> is the bigger operational enabler. If your team needs templating, bulk asset management, or external workflow integration, this opens the door to automation beyond the UI. It matters most for scaled programs and multi-region teams. You\u2019ll want strong controls around versioning, QA, and approval flow so automation doesn\u2019t create uncontrolled email sprawl.\r\n\r\n<b>AI image generation in Email Designer<\/b> is incremental but useful for speed. It can reduce dependence on design bottlenecks for drafts, variants, and test assets. That said, the output still needs brand, legal, and quality review. Treat it as a productivity aid, not a substitute for governed creative production.\r\n\r\n<b>SEO feature deprecation<\/b> is a cleanup signal. If you used it, export anything you still need now and remove it from your operating model. If you didn\u2019t, this is noise. Either way, it shows Adobe is trimming legacy features, so avoid building process dependencies on low-priority Marketo functionality.\r\n\r\n<b>Merge Leads limit and access_token deprecation<\/b> are integration risks, not feature updates. The merge limit matters if you run large dedupe or data hygiene jobs; those workflows need redesign before they fail. The authentication change is more important operationally: every REST integration should be checked, because token-in-query-string patterns will break and SOAP migration work may be more extensive than it looks.","button":null},{"acf_fc_layout":"layout_form","image":null,"title":"More great resources like this?
