Managing social media approvals with spreadsheets, emails and chat threads is inefficient and error-prone. In 2025, agencies and social media managers need robust approval tools to keep workflows smooth, maintain quality and collaborate seamlessly. This article reviews the best approval tools available and explains how to choose one for your team.
Why approval tools matter
Without a structured workflow, content can slip through the cracks or go live without proper review. Approval tools centralise feedback and reduce confusion by:
- Providing a clear approval chain. You can assign roles (creator, reviewer, approver) and see timestamps for each action.
- Tracking changes and version history. Every edit and comment is logged so you know who changed what and when.
- Enabling real-time collaboration. Teams and clients can comment, tag colleagues and resolve feedback directly in the post.
- Storing assets and guidelines. Keep brand assets, style guides and campaign briefs in one place instead of scattered across folders.
- Integrating scheduling and analytics. Once approved, posts can be scheduled or published automatically and performance metrics fed back into your workflow.
When you use a dedicated approval platform, you save time, reduce errors and build trust with clients.
What to look for in an approval tool
To choose the right platform, evaluate these features:
- Ease of use. The interface should be intuitive for internal teams and external approvers. A tool that requires extensive training won’t get adopted.
- Workflow flexibility. Can you customise approval steps, assign multiple reviewers and set deadlines? Look for support for parallel and sequential approvals.
- Multi-workspace support. Essential for agencies handling many clients; each brand should have its own space, calendar and permissions.
- Collaboration features. Comments, mentions and tasks should be linked to posts or assets, not scattered in email. Look for @mentions, threaded conversations and file attachments.
- Version control and audit trail. You should see who changed what and when. Being able to revert to previous versions is crucial for compliance.
- Integrations. Connections to design tools, asset libraries, social networks, project management platforms and analytics systems simplify your process.
- Reporting and analytics. Insights into approval turnaround times, rework rates and post performance help you optimise your process.
- Pricing. Consider whether plans are per user, per workspace or per client, and whether they scale with your agency’s growth.
21M Space
Designed specifically for agencies and freelancers, 21M Space offers multi-workspace calendars, drag-and-drop approvals and granular permissions. You can invite clients as guest approvers, share posts for feedback, resolve comments and publish directly to social channels. The platform includes templates for posts, email notifications, a central asset library and real-time analytics. Pros include:
- Separate workspaces for each client with color-coded calendars.
- Customisable approval flows with sequential or parallel steps.
- Built-in checklists and templates to standardise content reviews.
- Comment threads anchored to specific posts and assets.
- Integrations with design tools, cloud storage and social platforms.
- Comprehensive audit trail with version history and change logs.
A potential downside is that advanced features may require a paid plan, but 21m Space scales from solo freelancers to large agencies with dozens of clients.
Planable
Planable is a popular tool with a visual calendar and collaborative post editor. Teams can create posts for multiple channels, invite clients to approve via email and see comments inline. Key features include:
- Drag-and-drop calendar with preview of posts across channels.
- Real-time commenting and editing within the post composer.
- Support for multi-workspaces and user roles.
- Ability to export posts and approvals into PDFs or spreadsheets.
However, Planable lacks deeper workflow customisation, such as multi-stage approvals or automated reminders, and its analytics are limited compared to dedicated agency platforms. Pricing is per user, which can become expensive as your team grows.
Notion & Trello (with add-ons)
Tools like Notion and Trello aren’t purpose-built for social media approvals, but with templates and automations they can handle simple workflows. For example, you can set up boards or databases to track post status, assign tasks and collect feedback. Advantages include:
- High flexibility to design your own workflow using boards, cards or databases.
- Integration with numerous third-party apps via Zapier or native connectors.
- Low cost or free plans for small teams.
The downsides: these tools require manual configuration, lack native scheduling or social integrations, and don’t offer version control or approval chains. They’re better suited to small teams or budgets who need a lightweight solution.
Hootsuite & Buffer
Traditional social media management platforms like Hootsuite and Buffer include basic approval steps and scheduling features. You can assign posts for approval, schedule content across channels and view analytics. Strengths include:
- Unified dashboard for publishing, monitoring and reporting.
- Native integrations with most major social networks.
- Basic approval workflows and team collaboration.
Limitations: their approval workflows are less robust than dedicated approval platforms, and multi-client management can be cumbersome. Pricing can also increase significantly as you add more users or features.
Comparison summary
Here’s how these tools stack up:
- Best for multi-client agencies: 21m.space provides scalable workspaces, comprehensive approval flows and analytics tailored for agencies.
- Best for visual collaboration: Planable offers an intuitive calendar and post preview for quick approvals.
- Best DIY option: Notion or Trello can work if you’re comfortable building your own templates and don’t need deep integrations.
- Best all-in-one platform: Hootsuite and Buffer combine approvals with publishing and reporting, ideal if you already use them for scheduling.
Conclusion
