If you are searching for this, you have already felt the pain:

  • You send a Google Drive link to a customer on Outlook and they cannot open it.
  • An executive on an old corporate email keeps getting “request access” loops.
  • You flip a document to “Anyone with the link” just to get things moving… and then quietly worry where that link will end up.

You are not being paranoid. Misconfigurations and over-permissive sharing ("anyone with the link") are now a well-documented cause of real data leaks in Google Drive and other cloud tools. Without identity-bound access, you lose control over distribution.

Let's walk through why this is hard, what a good solution should actually do, how to get there with Peony, and what you can fall back to if you cannot use Peony yet.

1. Why not just use Google Drive?

To be fair, Google Drive is excellent for internal collaboration. The trouble shows up when you mix:

  • Non-Gmail recipients Google’s own docs acknowledge that sharing sometimes requires the other side to have a Google account, or to sign up for one, which is friction you feel immediately when someone is on corporate Outlook or a legacy email domain.

  • Public or "anyone with the link" links To avoid that friction, people often flip files to "anyone with the link can view." Multiple security write-ups now call that setting out as a major risk: it bypasses authentication, is easy to mis-share, and can leave data exposed for years if nobody reviews old links.

  • Lack of visibility once shared Unless you layer on DLP and detailed auditing, it is hard to see who outside your domain is actually opening what. Google Workspace DLP can help at the admin level, but many smaller teams never turn it on.

  • Shared drives limitations Shared drives still have restrictions with some non-Google identities, and troubleshooting those edge cases is painful for both sides.

So you end up in one of two bad modes:

  1. "Everyone please create a Google account" (slow and annoying), or
  2. "Fine, here's an open link" (fast but risky).

You deserve a third option.

2. What you actually want from a better solution

If we strip away the noise, the job to be done is simple:

“I want to send this to people on any email address, have it just work for them, and still keep real control over the file.”

In practice, that means your ideal tool should:

  1. Treat any email address as a first-class citizen No forcing account creation on the recipient’s side just to read a doc.

  2. Authenticate access without over-sharing

    • Share by specific email(s) or domain(s).
    • No need for “anyone with the link” hacks.

  3. Centralise documents behind one secure link

    • You share a link to a controlled space (room/dataroom), not ten separate file URLs.
    • You can update or add files without changing the link.

  4. Give you clear security controls

  5. Let you revoke and expire cleanly

    • When a project ends, you can turn access off for that client, firm or address in one place using access revocation.

  6. Provide basic analytics

    • Who opened what, when with page-level analytics.
    • Enough information to sanity-check that nothing weird is happening.

This is the gap Peony is designed to fill. Secure document sharing platforms provide all of this in one place.

3. How to share securely with any email using Peony (step by step)

Here is a workflow you can reuse for clients, investors, vendors, auditors – regardless of whether they use Gmail, Outlook, Yahoo, or a corporate mail server.

Step 1 – Decide the “bundle” you want to share

Instead of thinking in terms of individual attachments, think in terms of a mini-portal:

  • For a client: “Proposal + SOW + pricing sheet + deck.”
  • For an investor: “Deck + metrics + data room docs.”
  • For a partner: “Contract + onboarding docs + manuals.”

You want each of these to live behind one stable link per relationship.

Step 2 – Create a room in Peony

In Peony:

  1. Create a room named for the context, for example:

    • “Client – ACME 2025 Docs”
    • “Investor – Seed Round Pack”
    • “Vendor – Contract & Onboarding”

  2. Upload all relevant files (PDFs, Word, Excel, slides, ZIPs).

This room is now the “home” for that relationship’s documents.

Step 3 – Add non-Gmail recipients by email

Inside the room's access settings:

  • Add each person's actual email address, regardless of provider (e.g. cfo@client.co.uk, jane@fund.com, alex@company.de) using identity-bound access.
  • Add passwords to Peony rooms for an additional layer of protection—you can require both identity verification and a password.
  • Optionally, grant access to an entire domain (e.g. @client.com) when you are comfortable with that.

You are not asking them to switch tools; you are just saying, "Here is a secure link; it works in your browser."

Step 4 – Configure permissions & security

For each external contact or group, choose:

  • View-only vs download

  • Watermarking

    • Turn on per-viewer watermarks so any screenshot or PDF export clearly carries the recipient's identity, which is a strong behavioural deterrent.

  • Screenshot protection (where supported)

    • Enable screenshot protection so common capture shortcuts and tools are blocked or degraded, further raising the cost of casual exfiltration.

You now have a significantly stronger posture than an open Drive link to anyone with the link.

Step 5 – Add a passcode if required

If a counterpart or your internal policy insists on "password protection":

  • Add a passcode to the room or link in Peony using password protection.
  • Share that passcode via a separate channel (SMS, phone, Signal).

This gives you both:

  • Identity-based access via email; and
  • A second factor that is not stored in the same place as the link.

Step 6 – Share the single link

Now you can email any non-Gmail user:

“Here’s a secure link to your documents. You can open it directly with your email address; you do not need a Google account.”

If you later tweak the doc set, you update files in Peony; the link in their inbox stays valid and always points at the latest version. If the relationship ends, you remove or downgrade their access once using access management, and you are done. See who accessed documents with page-level analytics: when, how long they viewed them, and which parts they engaged with.

4. Other methods if you cannot use Peony

If Peony is not available yet, here are honest alternatives.

A) Google Drive with careful configuration

You can:

  • Share directly with non-Google addresses (Drive now supports this in many cases).
  • Avoid "anyone with the link"; keep access restricted to named users.
  • Use Workspace DLP and admin policies to warn or block risky external shares.

This improves things, but you still lack a neutral, brand-consistent experience for non-Google recipients and easy, relationship-level bundling. Peony provides identity-bound access, password protection, watermarking, and tracking for secure cross-platform sharing.

B) OneDrive / SharePoint

OneDrive and SharePoint let you:

  • Share links with external users, including non-Microsoft accounts.
  • Set passwords and expiration dates on "anyone" links in many Microsoft 365 plans.

This is solid for Microsoft-centric organisations, though still tied to that ecosystem.

C) Dropbox and similar tools

Dropbox allows:

  • Sharing with people who do not have a Dropbox account via simple links.
  • View-only or edit access on links, plus advanced features such as link passwords and expirations on paid plans.

Again, better than attachments, but scattered across different clients and UIs.

5. Practical tips so this becomes your default, not a one-off fix

To make cross-provider sharing with non-Gmail users calm and sustainable:

  • Decide which flows always go through a secure room For example:

    • Client deliverables
    • Investor and M&A docs
    • HR, legal, and finance docs These should never be ad-hoc attachments.

  • Standardise on “single secure link per relationship” Rather than sending individual files over and over, create one Peony room per client/fund/vendor and keep that as the canonical place people go.

  • Stop using "anyone with the link" for sensitive docs Across Google Drive, OneDrive, Dropbox, that setting is consistently flagged as one of the biggest external-sharing risks.

  • Train your team on one simple mental model

    "If the recipient is outside our domain – especially if they don't use Gmail – and the docs matter, we send a secure link to a Peony room, not a raw Drive link or attachment."

When you do that, "sharing with non-Gmail users" stops being a messy edge case and becomes a first-class, well-understood flow: any email is welcome, security is consistent, and you stay in control of the documents that actually matter.
