OttoKit keeps widening its WordPress trigger surface one plugin at a time
A side-by-side editorial comparison of Formidable Forms and Sender — release velocity, themes, recent moves, and the top alternatives to consider.
Formidable widens MCP compatibility and locks down signature files
Forms API v2.0.1 makes the Formidable MCP server tolerate the older MCP adapter versions bundled in other plugins such as WooCommerce and Rank Math, instead of refusing with an incompatibility message. Digital Signature Forms v3.2 adds form-level protection for signature files, a role requirement to access them, and permanent deletion of old signatures when an entry is deleted.
Sender is filling out from a budget email tool into a fuller marketing platform, now reaching into transactional sends.
Sender publishes on a monthly-digest cadence, mixing genuine release notes with SEO tutorials, so the release signal sits inside the 'Product Update' posts rather than in the feed's headline count. The August digest is explicit that most of the recent work was infrastructural and only now surfacing, with a rebuilt subscriber import — a guided, step-by-step flow that works on phone as well as laptop — as the visible piece. Earlier digests carried ecommerce reports down to the Standard plan, a refreshed email builder with brand settings, and before that transactional email and a rebuilt dashboard.

Two threads are running in parallel across the add-on family. One is agent access, opened by the Forms API v2.0 MCP adapter and the WordPress Abilities API, now being made to coexist with the other plugins already shipping MCP adapters on the same site. The other is a sustained security pass, visible in signature file handling, tokenized CSV downloads, and the Stripe and core-plugin hardening earlier in the window.
Adapter-version collisions between plugins are likely to recur as more WordPress plugins ship MCP servers, so expect further compatibility patches rather than new API surface in the near term.

Earlier digests carried ecommerce reports down to the Standard plan, a refreshed email builder with brand settings, and before that transactional email and a rebuilt dashboard.
The arc is a low-cost SMB email tool acquiring the pieces that let it be the only marketing vendor a small store buys: transactional sends, ecommerce reporting, landing pages, brand-consistent templates, and now a rebuilt onboarding path into the list itself. Plan-tier moves like pushing ecommerce reports into Standard suggest the strategy is reach rather than upsell. Entry-point friction — import, builder, brand settings — is getting the same attention as the send-side features.
The August note that months of under-the-hood work is only beginning to surface points to further platform-level releases in the next digests; import and deliverability plumbing are the likely next visible outputs.
