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.

What is Clay?

Clay lets teams publish workflows as templates and adds healthcare data.

Clay is a go-to-market data platform that combines enrichment, audiences, ads and outbound sequencing. Late October brought Claygent Auto-mode, which picks a model per row for cost, plus MCP client allowlists and per-workflow credit caps. The week of November 2 added Workflow Templates that anyone can copy, a Definitive Healthcare integration, Salesforce traffic through a customer's own proxy, and tags for Audiences segments.

Mailjet vs Clay: editorial side-by-side

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.

Clay

5.0

Clay lets teams publish workflows as templates and adds healthcare data.

◆ Current state

Clay is a go-to-market data platform that combines enrichment, audiences, ads and outbound sequencing. Late October brought Claygent Auto-mode, which picks a model per row for cost, plus MCP client allowlists and per-workflow credit caps. The week of November 2 added Workflow Templates that anyone can copy, a Definitive Healthcare integration, Salesforce traffic through a customer's own proxy, and tags for Audiences segments.

◆ Where it's heading

Clay ships a weekly roundup that alternates between widening its data sources and adding the admin controls larger customers ask for. Workflows have become its main unit, now with budgets, triggers from signals and, with templates, a way to share them between workspaces.

◆ Prediction

Expect templates to grow into a shared gallery and more vertical data providers like Definitive Healthcare to follow.
