Attach

Overview

Attach is a document-sharing and content-management tool for sales teams that want more visibility and control after sending material. It suits sales representatives and marketers who share proposals or approved collateral; its appeal is trackable links and access controls, while the free plan’s three-document cap is restrictive for ongoing use.

Founded in 2011, Attach is aimed at startups and sales leaders as well as individual sales and marketing users. A free plan and a 14-day trial provide ways to start, but custom pricing makes it difficult to judge the cost of expanding beyond the free tier.

Key features

Tracked sharing and document controls

Attach reports opens, viewers, time spent on each page, navigation, close events, approximate city, device type, viewer count, and forwarding. That detail can help sales teams understand which material attracts attention and whether it is being passed on, although approximate city is not precise location data.

Senders can password-protect documents, disable downloads or viewing, set an expiration date, and delete or replace files after sending. These options are useful when access needs to be limited or a shared version becomes outdated. Uploads support PDF, PowerPoint and Word files up to 30 MB each; there is no stated upload-count limit, but the free plan’s three-document cap remains the practical constraint for free users.

Shared content library and integrations

A centralized library gives teams a place to keep approved sales and marketing content, share current versions, and review performance. Attach also supports content approval workflows, expiry controls, basic personalization, and buyer engagement analytics. That combination is more relevant to teams managing shared collateral than to users who only need a one-off file transfer.

Integrations include Dropbox, Box, Google Drive, Microsoft OneDrive, Salesforce, Gmail, Outlook, Zapier, and Base. The Gmail Chrome Extension lets users share tracked documents from Gmail, a useful fit for sales teams that work from their inbox. Attach says uploaded documents remain the user's property, are securely stored, and can be deleted or downloaded again. Support requests are directed to Cirrus Insight support.

Pricing

Attach uses a freemium model. The free plan costs nothing, covers up to 3 documents, and requires no credit card. That is enough to try the sharing and tracking workflow, but the small cap limits its usefulness as a standing library for a team.

A free 14-day trial is also advertised. Paid plans use custom pricing, so teams should confirm the cost and terms before relying on Attach beyond the free allowance; no seat count, paid-tier quotas, or renewal terms are provided. The free plan is the clear starting point for an individual or small team evaluating the product, while an organization with sustained document volume should establish the paid-plan fit first.

Platforms

Attach is available on the web and as an extension. The Gmail Chrome Extension is specifically suited to sharing documents from Gmail; broader extension details are not established.

Who it's for

Attach is best suited to sales representatives, marketers, startups, and sales leaders who distribute documents and need both access controls and engagement signals. Teams with approved collateral to maintain can also benefit from its shared content hub and workflows. It is a weaker fit for anyone needing a large free document library or a clear paid-plan budget before evaluation.

Pros and cons

• Pros: Page-level engagement data, forwarding visibility, and viewer context offer more insight than a basic share link.
• Pros: Passwords, viewing and download restrictions, expiry, and post-send replacement or deletion give senders practical control over shared files.
• Pros: The content hub, approval workflows, and integrations support teams that need to keep shared sales material current.
• Cons: The free plan stops at three documents, which is a meaningful limit for recurring team use.
• Cons: Paid pricing is custom, making cost comparison and budget planning harder before contacting the provider.
• Cons: Uploads are limited to 30 MB per file, and the Gmail extension's stated use is specific to Gmail.

Alternatives

Airstride is a better direction for teams focused on partner management, deal management, account mapping, and CRM integration, with a free tier for up to three partners rather than Attach’s document tracking.

Cirua may suit an individual seeking a personal asset library: its free plan includes one user seat and 5 GB of workspace storage, while Attach centers on sales document engagement.

Content Camel is worth considering for a content library with a free one-user Solo plan and one published site; Attach is more directly focused on trackable document sharing and controls.

Dock may fit teams looking for workspaces and assets such as playbooks, courses, and order forms, with a free plan that caps those items; Attach emphasizes document-level analytics and access management.

Bigtincan Digital Sales Rooms is another option for digital sales rooms and shares, with pricing available by contacting sales.

Enablix offers custom annual-contract pricing with per-user charges, making it an option for teams evaluating a tailored sales enablement platform.

Highspot is a paid alternative offering governed content, AI-powered search and answers, sales plays, digital sales rooms, and CRM integration.

QuarkXPress is a paid alternative with a prepaid annual subscription that renews automatically.

Verdict

Choose Attach if your sales team needs to share controlled document links and see how buyers engage with them, especially when a shared library and Gmail-based workflow matter. Its free plan is a low-friction trial, but the three-document cap and custom paid pricing make it a less convincing choice for teams that need predictable costs or substantial ongoing capacity.
