What is Clay?

Clay pushes past enrichment into ad activation while cheaper models reset what Claygent costs to run.

Clay ships weekly roundups, and two threads run through them. Audiences is becoming a system of record — BigQuery, HubSpot Deals and Salesforce Activities import into it, and it now reports the pipeline and closed-won revenue that Clay-sourced accounts drove. Claygent is becoming both cheaper and more autonomous, picking up open-weight model options and an inbox it can answer on its own. Around both, Clay is instrumenting credit spend hard: time-series graphs, per-function and per-user attribution, CPJ allowance tracking.

What is Mailchimp?

Mailchimp's recent feed is mostly a 2023–2024 changelog reindex; real shipping is the early-April ecommerce update.

The top of Mailchimp's feed is a reindexing artifact — six historical changelog entries from 2023, 2024, and 2025 (HTTP 404 semantics for invalid template names, expanded webhook retry behavior, DKIM/DMARC sending-domain requirements, attribution-model overwrites of campaign_id, TLS 1.0/1.1 retirement, Audiences BETA endpoints) all tagged with a May 5, 2026 capture timestamp. The actual recent shipping sits below the top window: an early-April 'biggest update ever' aimed at ecommerce — Shopify SMS bidirectional consent sync, Judge.me and Yotpo review integrations, on-brand transactional emails via an in-app editor, a refreshed marketing dashboard, back-in-stock popup forms, and dynamic ecomm data in messaging.

Clay pushes past enrichment into ad activation while cheaper models reset what Claygent costs to run.

◆ Current state

Clay ships weekly roundups, and two threads run through them. Audiences is becoming a system of record — BigQuery, HubSpot Deals and Salesforce Activities import into it, and it now reports the pipeline and closed-won revenue that Clay-sourced accounts drove. Claygent is becoming both cheaper and more autonomous, picking up open-weight model options and an inbox it can answer on its own. Around both, Clay is instrumenting credit spend hard: time-series graphs, per-function and per-user attribution, CPJ allowance tracking.

◆ Where it's heading

Clay is moving from a table that enriches data toward a platform that also acts on it — sourcing a market, enriching it, attributing revenue to it, and now syncing it to six ad platforms. The volume of credit-visibility work is the tell: customers are running enough agent workload that spend has become the thing they ask about, and cheaper models plus better dashboards are both answers to the same complaint. Activation is the newest edge and the least built out.

◆ Prediction

Expect the activation surface to widen — more ad and sequencing destinations in the shape of the Nooks integration and Ads 2.0 — and expect credit economics to keep getting features, since every roundup in this window carried at least one spend-visibility item.

Mailchimp's recent feed is mostly a 2023–2024 changelog reindex; real shipping is the early-April ecommerce update.

◆ Current state

The top of Mailchimp's feed is a reindexing artifact — six historical changelog entries from 2023, 2024, and 2025 (HTTP 404 semantics for invalid template names, expanded webhook retry behavior, DKIM/DMARC sending-domain requirements, attribution-model overwrites of campaign_id, TLS 1.0/1.1 retirement, Audiences BETA endpoints) all tagged with a May 5, 2026 capture timestamp. The actual recent shipping sits below the top window: an early-April 'biggest update ever' aimed at ecommerce — Shopify SMS bidirectional consent sync, Judge.me and Yotpo review integrations, on-brand transactional emails via an in-app editor, a refreshed marketing dashboard, back-in-stock popup forms, and dynamic ecomm data in messaging.

◆ Where it's heading

The clear bet is an ecommerce-tilted Mailchimp: review integrations, post-purchase flows, back-in-stock automation, Shopify-side SMS without email. Combined with the older Audiences BETA work that allowed contact creation from a phone number alone, the platform is reshaping around audiences that don't necessarily start with email. Transactional and Marketing surfaces are converging — same in-app editor, same brand controls, same dashboard.

◆ Prediction

Expect deeper Shopify-side integrations (more bidirectional sync, native checkout-stage triggers), additional review-platform partners beyond Judge.me and Yotpo, and continued blurring of the Marketing/Transactional product line — likely a unified billing or packaging surface eventually. The historical changelog reindex should drop off the front of the feed as new entries push it down.
