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 Swello?

Swello adds team post approval and multi-language AI writing to its social scheduling core.

Swello is a French-market social media scheduling tool serving agencies and community managers managing client accounts. Recent product work has layered collaboration features onto its scheduling core: a post validation workflow where team members and clients can comment, request corrections, and approve content before it publishes, plus tracking of who last edited each post. Alongside platform features, Swello has invested heavily in content marketing through its 'Follow Back' podcast targeting social media professionals.

Mailjet vs Swello: 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.

5.0

Swello adds team post approval and multi-language AI writing to its social scheduling core.

◆ Current state

Swello is a French-market social media scheduling tool serving agencies and community managers managing client accounts. Recent product work has layered collaboration features onto its scheduling core: a post validation workflow where team members and clients can comment, request corrections, and approve content before it publishes, plus tracking of who last edited each post. Alongside platform features, Swello has invested heavily in content marketing through its 'Follow Back' podcast targeting social media professionals.

◆ Where it's heading

The product is moving toward agency-grade workflow tooling — approval chains, collaborative editing, a forthcoming notifications and mentions center, and a private messages/comments inbox. The UI translation into 11 languages and AI-powered post translation into 13 suggest a deliberate push beyond the French-speaking market into broader European agency accounts. Teased AI assistant features point toward automating more of the content creation cycle, not just scheduling.

◆ Prediction

The next release will likely be the notifications and @mentions center signaled in the approval workflow announcement, completing the team collaboration loop. The private messages/comments inbox has also been previewed as imminent and would meaningfully expand Swello's engagement surface.
