What is Clay?

Clay consolidates its Audiences and Ads plumbing after a month of launches.

Clay ships weekly roundups that push its enrichment workspace into execution: Sequencer 2.0 for cold outbound, Ads with LinkedIn company-list syncs, and Ads control from the CLI and coding agents. Spend controls have tightened alongside, from workspace credit budgets to auto top-ups to per-workflow budgets. The latest week is consolidation: a redesigned home page, one view of every Audiences source and export, and ad match-rate reporting that lines up with each ad platform.

What is Mailjet?

Mailjet is publishing deliverability compliance guidance, and little else.

A low-cadence blog — ten posts spanning eight months — weighted toward authentication and regulatory change rather than product. The substantive entries are two treatments of the CNIL and Garante tracking-pixel guidance in France and Italy, and a DMARC post that states a real product default: Mailjet is DKIM-first. The rest is competitive migration content, a platform comparison still labelled 2025, and research published under the sibling Mailgun brand.

Clay vs Mailjet: editorial side-by-side

C
Clay
MARKETING
5.0

Clay consolidates its Audiences and Ads plumbing after a month of launches.

◆ Current state

Clay ships weekly roundups that push its enrichment workspace into execution: Sequencer 2.0 for cold outbound, Ads with LinkedIn company-list syncs, and Ads control from the CLI and coding agents. Spend controls have tightened alongside, from workspace credit budgets to auto top-ups to per-workflow budgets. The latest week is consolidation: a redesigned home page, one view of every Audiences source and export, and ad match-rate reporting that lines up with each ad platform.

◆ Where it's heading

Clay is turning into the system where go-to-market teams act on data, and increasingly where agents act on it for them through the MCP server and CLI. After launching outbound and ads, recent weeks have gone into making those surfaces trustworthy: reporting that matches the ad platforms, auditable syncs, and exports routed through Workflows.

◆ Prediction

Expect more of the Ads and Audiences surface exposed to Workflows, the CLI and agents, alongside finer spend controls. The entries don't show which channel after LinkedIn gets company-list syncs next.

M
Mailjet
MARKETING
2.5

Mailjet is publishing deliverability compliance guidance, and little else.

◆ Current state

A low-cadence blog — ten posts spanning eight months — weighted toward authentication and regulatory change rather than product. The substantive entries are two treatments of the CNIL and Garante tracking-pixel guidance in France and Italy, and a DMARC post that states a real product default: Mailjet is DKIM-first. The rest is competitive migration content, a platform comparison still labelled 2025, and research published under the sibling Mailgun brand.

◆ Where it's heading

The positioning is compliance-and-deliverability first, which is the pitch of an infrastructure sender rather than a campaign tool — the transactional-plus-marketing post argues exactly that, against teams running two platforms. The Mailchimp migration guide and the comparison roundup point at where Mailjet expects to win customers: cost and consolidation, not features. Nothing in the window describes a shipped capability.

◆ Prediction

More regulatory response content is the safest read, since two of the last ten posts already cover the same EU pixel guidance; on product direction this source is silent and a release feed would be needed.
