Hardware & logistics
“Just email it to me” is the most fragile plan in the building.
It's the default move: mail the deck to yourself or the host, open it on the room's machine, present. It works often enough to feel safe, and fails in exactly the ways that hurt most — size limits and version confusion.

"Can you just email me the presentation and I'll pull it up?" It sounds like the safe, universal option. Then the send bounces because the file's too big, or it arrives and it's yesterday's version, or the host opens it and half the fonts have shifted. The most common presentation handoff on the planet is also one of the most brittle.
✕ The myth
"Email always works — everyone has it."
Attach, send, open. What could be simpler or more reliable?
✓ The reality
Two failure modes, every time.
Email caps attachments (Gmail 25 MB,1 Outlook ~20 MB2), and once a file is flying around inboxes, version drift is inevitable.
A real, image-rich deck routinely exceeds those limits,12 so you compress it, split it, or upload it to a drive and paste a link — adding steps and copies at the exact moment you wanted simplicity. And every emailed copy is a fork: the host might open "Deck_v3_final_FINAL.pptx" while you've been editing "…final_v4." The workflow's very convenience is what scatters versions.
The real problem isn't size — it's copies
Attachment limits are annoying but solvable. The deeper issue is that emailing a deck makes a copy, and copies drift: someone presents the wrong one, an old logo reappears, a corrected figure un-corrects itself. The most reliable presentation is one that never left your device — where there is exactly one version, the one on your screen, because you're showing it directly rather than shipping it ahead.

Drift
Every emailed copy is a fork waiting to be presented by mistake.
⚖ The honest bit — email is fine for small, final files
The issue is big decks and live edits, not email itself.
Fair's fair: if your deck is a lean, finished PDF under the limit and won't change, emailing it to the host is perfectly reasonable — universal, familiar, done. Email as a delivery mechanism for a settled document is fine. It falls down specifically for large, image-heavy files and for anything you're still refining, where size limits and version drift bite. Match the tool to the case: small and final, email away; big or evolving, don't ship copies at all.
Where SyncBy!App fits
SyncBy removes the handoff entirely: you present from your own device to the room's screen, so there's no attachment to squeeze under a limit and no second copy to drift out of sync. The version you're looking at is the version the room sees — always. When you do want the host to keep a copy, send them a small final PDF on purpose; for getting it on screen, skip the inbox.
TL;DR
- Email caps attachments (~25 MB Gmail, ~20 MB Outlook); real decks exceed it.12
- Worse, every emailed copy forks — version drift means someone shows the wrong one.
- Presenting from your own device keeps exactly one version: the one on screen.
- Honest caveat: for a small, final PDF, emailing it is perfectly fine.
