Email Attachment Alternative
Email attachments are a black hole.
You've been attaching PDFs to emails your entire career. It works. Sort of. You send the proposal, you wait, you follow up with "just checking if you had a chance to look at this," and you hope for the best.
There's a better way. Same email, but instead of attaching the file, you paste a tracking link. Now you know exactly what happened.

Email gives you zero analytics.
No opens, no reads, no insight.
Attachments were designed for convenience, not intelligence. Here's what changes when you switch to a link.

The real cost of email attachments
Email attachments feel free, but they carry hidden costs that compound across every document you send.
Deliverability problems you never see
Corporate email servers, ISPs, and spam filters treat attachments from unknown senders as security risks.[2] Some email providers automatically block PDF attachments entirely.[1] The worst part: you typically won't receive a bounce-back notification when your email fails to deliver.[2] Your proposal could be sitting in a spam folder right now, and you'd never know.
When your emails with PDF attachments are repeatedly flagged, your sender reputation degrades. This means even future emails without attachments are more likely to land in spam.[1] You're not just risking one email — you're poisoning your entire sending domain.
File size hits a wall
As much as 58% of users regularly encounter issues sending PDFs due to file size limitations.[4] Most email providers cap attachments at 10–25 MB, and if your file exceeds the recipient's server limit — which may differ from yours — it simply won't arrive.[4] Compressing the PDF degrades image quality, blurs text, and undermines the professional document you worked to create.[4]
Mobile is broken
More than 71% of people check their email on a mobile device.[1] Large attachments slow download times dramatically on mobile, and recipients in areas with limited connectivity often abandon the email before the file loads.[1] Phones also have limited storage, making downloads even more inconvenient.[4] A ShareDoc link opens instantly in the browser — no download, no storage impact, no waiting.
ShareDoc links avoid all of these problems.
No attachment for spam filters to flag. No file size limits. Instant mobile viewing. And you get analytics on top.
What you lose with email attachments: sales intelligence
Every PDF you attach to an email is a missed opportunity to learn about your prospect. With attachments, you lose the chance to qualify leads and understand whether your content resonated, why it mattered, and how engaged the reader actually was.[2]
No open tracking
You don't know if your prospect opened the proposal, downloaded it, or let it sit unread in their inbox for two weeks.
No page-level engagement
Did they read the pricing section? Did they skip the case studies? Did they spend 8 minutes on the technical specs? With an attachment, you'll never know.
No follow-up signals
You lose your natural excuse to reconnect with context. Instead of "I noticed you spent time on the pricing page — want to walk through the options?" you're stuck with "just checking in."[2]
No lead capture on forwards
When a prospect forwards your attachment to their team, you have no idea who else read it. ShareDoc captures every viewer — even forwarded recipients — with optional email gates.
Prospects also value what they ask for more than unsolicited attachments you offer.[2] A ShareDoc link feels like a resource to explore, not a file dumped in their inbox.
Brand and security risks of email attachments
Version control breaks across teams
In larger sales teams, each salesperson ends up producing different versions of the same document — varying designs, colors, logo sizes, and fonts.[6] When five reps send five different versions of the same proposal, the customer sees inconsistent branding and messaging. This creates a confusing experience that undermines trust.[6]
With ShareDoc, there's one link per document. Update the PDF once, and every recipient — past and future — sees the same current version. No more outdated pricing sheets floating in inboxes from three weeks ago.
Files on multiple devices increase attack surface
Sending a document by email means the same file is now stored on your computer, your outbox, every recipient's inbox, and every recipient's device.[6] That's multiple copies across multiple locations, each one a potential target for a data breach.[6]
ShareDoc keeps the document in one place. Recipients view it in their browser without downloading. If you need to revoke access — after a deal falls through, a partnership ends, or sensitive information changes — you disable the link. The file never lived on their device.
Mailbox bloat and storage limits
Large attachments fill up recipient mailboxes quickly, leading to bounced emails — particularly if the recipient isn't expecting a large file.[1] Most email providers impose storage limits on user accounts.[1] A link takes zero storage in the recipient's inbox.
Who should keep using email attachments
Email attachments still make sense in some cases:
- Internal docs between colleagues who don't need tracking
- Quick personal file sharing where analytics don't matter
- Files that need to live permanently in someone's inbox for reference
If you just need to get a file from point A to point B and don't care what happens after, an attachment is fine.
Who should use ShareDoc instead
If knowing whether your PDF was read matters to your work, ShareDoc is the better choice:
- Sales proposals — know if the prospect read your pricing section before the follow-up call
- Pitch decks — see which investors actually opened your deck and how far they got
- Reports and deliverables — confirm the client reviewed the work before sign-off
- Any PDF where "did they read it?" changes what you do next
Same email. Same workflow. Just a link instead of an attachment. The difference is what you learn after you hit send.
How to switch from attachments to tracked links
The switch takes less than a minute. Your email workflow stays the same — the only thing that changes is what you paste.

Frequently asked questions
Is ShareDoc free to use instead of email attachments?
Yes. The free tier includes all features — open tracking, page-by-page analytics, time spent reading, lead capture, and link revocation. You only pay when you need higher volume.
Do recipients need an account to view ShareDoc links?
No. They click the link and view the PDF directly in their browser. No account, no app download, no friction. It looks and feels just like opening an attachment — except you get analytics on your end.
Can I still send the link via email?
Yes. Instead of attaching the PDF file, you paste the ShareDoc tracking link into your email. The recipient clicks it and views the document. You use the same email workflow — the only difference is a link instead of an attachment.
What analytics do I get that email attachments don't provide?
Open tracking with timestamps, page-by-page reading analytics, time spent per page, whether the viewer returned to the document, and optional email capture. Email attachments provide none of this.
Can I update the PDF after sending?
Yes. You can replace the PDF file while keeping the same tracking link. Everyone who has the link will see the updated version. With email attachments, you'd need to send a new email with the corrected file.
Do email attachments hurt my sender reputation?
Yes. Spam filters flag emails with PDF attachments as security risks.[2] When your emails are repeatedly flagged, your sender reputation degrades — meaning even future emails without attachments are more likely to land in spam.[1] ShareDoc links avoid this entirely because there is no attachment for filters to flag.
Why do large PDF attachments fail on mobile?
More than 71% of people check email on mobile devices, where large attachments slow download times significantly or fail entirely due to limited storage and spotty connectivity.[1] ShareDoc links open instantly in the browser — no download required.
How does ShareDoc help with version control across sales teams?
With email attachments, each salesperson may send different versions with inconsistent branding and pricing.[6] ShareDoc gives you one link per document — update once and every recipient sees the latest version. No more outdated proposals in inboxes.
