2.5

Hunter is annexing the sending stack, turning a lead-finder into a full outbound platform.

◆ Current state

Hunter has spent 2026 building outward from email-finding into the full outbound engagement stack. It now provisions domains and inboxes, warms them, paces their sending volume, scores their deliverability health, and runs A/B-tested sequences against recipient-based analytics. The original finder is now one entry point into an owned send-and-measure pipeline.

◆ Where it's heading

The throughline across these releases is deliverability ownership: nearly every recent feature reduces the user's dependence on an external email provider and on manual reputation management. Hunter is consolidating account management, health scoring, and volume pacing into one center, then bracketing it with AI lead discovery on the front and recipient-based reporting on the back. The product is converging on a closed loop — find, send, protect, measure — inside one tool.

◆ Prediction

Expect the next moves to deepen the owned-infrastructure bet: tighter automation between Inbox Protection, Progressive Sending, and sequence scheduling, and likely AI-assisted message drafting to pair with the existing A/B and Discover assistants.

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.
