Poststack

Poststack is a social media management platform built for Indian social media agencies managing multiple client accounts. It brings planning, client feedback, publishing, and reporting into one workspace, helping agencies reduce the need to coordinate work across chats, spreadsheets, and separate scheduling tools.

Each client gets a dedicated workspace with its own calendar, settings, and feedback history, while team members can work with per-action permissions. Client review happens through account-free magic links, allowing clients to approve posts or request changes without installing an app. With revision limits, official platform APIs, Indian billing support, and IST-native scheduling, Poststack is designed around the operational needs of agencies working in India.

Key Features

Multi-Client Workspaces

Manage multiple client accounts from a single workspace.

Poststack supports up to 30 client accounts, with each client keeping their own:

• Content calendar
• Settings
• Feedback history
• Connected social accounts
• Publishing workflow

This keeps client work separated while giving agency teams a central place to manage their overall workload.

Client Approval Links

Clients can review content through a magic link without creating an account or installing an application.

Approval activity stays connected to the relevant post, keeping:

• Comments
• Approval status
• Revision requests
• Feedback history

attached to the content being reviewed.

Revision Round Tracking

Poststack puts boundaries around revision cycles.

Revision rounds are capped and recorded, giving agencies a clearer record of how many changes have been requested and reducing the risk of feedback continuing indefinitely without a defined history.

Shared Planning Calendar

Plan and schedule content across connected client accounts through a shared calendar.

This gives account managers and social media teams a single planning view while maintaining separation between individual client workspaces.

Official API Publishing

Poststack publishes content through official platform APIs and OAuth.

Supported platforms include:

• Instagram
• Facebook
• LinkedIn
• X
• YouTube
• Threads

Using official authentication and publishing routes keeps social account connections within the supported platform workflows.

Social Media Reporting

Track published content and its performance through reporting features covering:

• Published content
• Reach
• Engagement

This gives agencies a central place to review client social media activity rather than assembling reports manually from different platforms.

Spreadsheet Import

Teams that already plan content in spreadsheets can import their existing planning data.

This helps agencies transition from spreadsheet-based workflows without requiring them to rebuild every content plan from scratch.

Per-Action Team Permissions

Team members can work with permissions based on individual actions.

This provides agencies with more control over who can perform specific tasks across the client workflow.

IST-Native Scheduling

Poststack is designed around Indian agency operations, including scheduling in IST.

This helps teams working with local clients and Indian business hours avoid manually converting scheduling times between timezones.

INR, GST & UPI Billing

The platform includes billing features designed for Indian businesses.

These include:

• INR pricing
• GST invoices
• UPI payments

This provides an agency-focused billing workflow that fits common payment and invoicing requirements in India.

DPDP Act Focus

Poststack is built around the Digital Personal Data Protection Act (DPDP Act), supporting its positioning as a platform designed specifically for Indian agency operations.

Built For Indian Social Media Agencies

Poststack is designed for agencies managing multiple clients and coordinating content between account managers, social media teams, and clients.

It is particularly useful for:

• Social media agencies managing multiple client accounts
• Account managers coordinating approvals and revisions
• Content teams planning and publishing across platforms
• Agency owners looking for tighter workflow control
• Indian marketing teams needing local billing and timezone support
• Growing agencies managing increasing client and content volume

Common Use Cases

• Multi-client social management: Manage up to 30 client accounts from one workspace.
• Content planning: Organize client content on shared calendars.
• Client approvals: Send magic links so clients can review content without an account.
• Revision management: Record and cap revision rounds to keep projects moving.
• Social publishing: Publish through official APIs across major social platforms.
• Agency reporting: Track published content, reach, and engagement for clients.
• Spreadsheet migration: Bring existing content plans into the platform.
• Team permissions: Control which actions individual team members can perform.
• Indian billing: Handle INR payments, GST invoices, and UPI.
• IST scheduling: Plan and publish content using an India-native timezone workflow.

Why It Matters

Agency social media work involves more than creating posts. Teams have to manage multiple clients, collect feedback, track revisions, schedule content, publish across platforms, and report on results. When those activities are spread across chats, spreadsheets, and separate tools, important feedback and approval records can become difficult to track.

Poststack brings these workflows together around the client account. Each client has a dedicated workspace, calendar, settings, and feedback history, while permissions help teams control who can perform specific actions.

The client review workflow is particularly focused on reducing friction. Clients can open a magic link, review the relevant post, leave comments, approve it, or request changes without creating another account or installing an application. Revision rounds are also capped and recorded, providing agencies with a clearer history of the review process.

The platform is also tailored to the Indian agency market. IST-native scheduling, INR pricing, GST invoices, UPI payments, and a DPDP Act-focused approach are built into the workflow rather than added as afterthoughts.

By combining client management, planning, approvals, publishing, and reporting in one workspace, Poststack gives Indian social media agencies a more organized way to manage growing client volume while keeping feedback and publishing records connected to the work.
