RetainIQ

RetainIQ is a full-service retention-marketing agency for direct-to-consumer (D2C) brands, delivering lifecycle email and SMS programs. Its work spans automated flows (welcome, cart abandonment, post-purchase, win-back, replenishment), weekly strategic campaign sends with design and copywriting, and deliverability/segmentation/list-hygiene infrastructure. A proprietary 1:1 personalization engine generates variant product blocks at scale. A Klaviyo Gold Master Partner and Omnisend partner, RetainIQ integrates with Shopify, Klaviyo, and Omnisend; plans start at $990/mo on month-to-month terms. It operates as a marketing-services agency and does not publish a public developer API, SDK, or documentation surface. RetainIQ Global Inc. previously shipped a self-serve Shopify app (listed 2021, free to install, $999 per 100K personalization credits); that listing is still live but appears retired in place — its application host returns a Cloudflare 522 and the developer website named on the listing now redirects to a domain-for-sale page.

RetainIQ is profiled on the APIs.io network. Tagged areas include Company, Ai, Retention Marketing, Email Marketing, and SMS.

RetainIQ’s developer surface includes engineering blog, support, pricing, and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/retainiq: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →

  detail: RetainIQ sells a managed retention-marketing service, not software with an interface — every contract and /.well-known/
    path on retainiq.io returns a real 404, its former self-serve Shopify app host app.retainiq.io returns Cloudflare 522,
    and the developer website that app listing names (wyde.ai) now redirects to a domain-for-sale page.
