Why won't my email send a large file?

Almost every email provider caps attachments at around 20 to 25MB — Gmail, Outlook, and most business mailboxes included. A single video off your phone can easily be three times that, so the email simply bounces back. Vaulex gets around it by keeping the file on our servers and emailing the recipient a download link instead of the file itself.

Do I need to install anything?

No. It runs in whatever browser you are already using — on a laptop, a tablet, or your phone on site. There is nothing to download, nothing to configure, and no IT person required.

Does the person receiving the file need an account?

No, and this is the bit people are usually most relieved about. They get an email with a download button. They click it, the file downloads, and that is the end of their involvement. No sign-up, no app, no password unless you chose to add one.

Yes. The free plan lets you send files up to 500MB, protect them with a password, and see when they have been downloaded. No card details, no trial that quietly starts charging you. If you need to send bigger files, or keep them available for longer, that is when a paid plan makes sense.

How big a file can I send?

500MB on the free plan, 2GB on Plus, and no limit at all on Pro. As a rough guide: 500MB is around 150 high-resolution photos or a few minutes of phone video. A full wedding gallery or a 4K edit will want Pro.

How long do my files stay available?

Two days on the free plan, seven days on Plus, and for as long as you want on Pro — where you can also set your own expiry date on individual links. Once a transfer expires the file is deleted from our servers, which is exactly what you want happening to old client data.

Is it secure enough for client information?

Every transfer travels over an encrypted connection, you can lock any transfer with a password, and links expire so nothing lingers indefinitely. We do not read your files, and we do not scan their contents for advertising. Vaulex Group Ltd is registered with the Information Commissioner's Office (registration ZC087196). If you are handling anything particularly sensitive, use the password option and set a short expiry.

Can I tell whether the file was actually downloaded?

Yes. Tick the notification box before you send and we will email you the moment your recipient downloads it. You can also see the status of every transfer in your dashboard, so you are never left guessing whether it arrived.

What is the difference between this and WhatsApp?

WhatsApp squashes your photos and videos to keep them small, so what arrives is noticeably worse than what you sent. It also needs the recipient's mobile number, and everything ends up on someone's personal phone. Vaulex sends the file exactly as you saved it, works by email or link, and keeps business files out of personal messaging apps.

Can I cancel whenever I like?

Yes. There is no contract and no minimum term. Cancel from your dashboard and you will not be billed again. Your plan carries on until the end of the period you have already paid for.

The problem

Your email will not send it. Here is why.

It is not you, and it is not your broadband. Every email provider puts a hard cap on attachment size — and it is far smaller than you would think.

What email lets you attach

Gmail 25 MB
Outlook 20 MB
Most work email 10 MB

And it is worse than the number suggests. Email has to re-encode every attachment before it sends, which inflates it by around a third. So a "25MB limit" is really about 18MB of actual file. That is why a 20MB video bounces off a 25MB cap and you are left staring at an error message that explains nothing.

What your files actually weigh

A few site photos ~40 MB
One minute of phone video ~130 MB
A minute of 4K footage ~350 MB
A day of photos from a job 500 MB+

All of the above sends fine on Vaulex. The free plan handles anything up to 500MB — around fifty times what most work email will take. We keep the file and email your customer a link instead, so there is nothing to bounce.

So people improvise. And every workaround costs them something:

Send it on WhatsApp

It arrives compressed to a fraction of the quality. Fine for a laugh, useless for a client deliverable or a snagging photo someone has to zoom into.

Split it into ten emails

Twenty minutes of your evening, and the customer still ends up missing part three and ringing you about it on Saturday.

Wrestle with a cloud drive

Sharing permissions, sign-in prompts, "request access" emails. Your customer just wanted the file, not an account.

How it works

Three steps. No software to install.

If you can attach a photo to an email, you can do this. Nothing to download, nothing to set up, and your customer does not need an account to receive the file.

Drop your files in

Drag them onto the box above, or click to browse. Photos, videos, drawings, invoices, a whole folder — it does not matter how big.

Type who it is going to

Add their email address, or grab a link to paste into WhatsApp. Add a password if it is sensitive. Then hit send.

We tell you when it lands

They click one button to download. You get an email the moment they do, so you are not left wondering or chasing.

Everything you need. Nothing you do not.

We stripped out the clever stuff nobody asked for and kept the six things that actually matter when you are trying to get a file to a customer before the end of the day.

Send a whole folder at once

Two hundred photos from a job, or one enormous video. Highlight the lot, drag it in, and it goes as one link. No zipping, no splitting it into parts.

Straight to their inbox

Type in their email address and we do the rest. They get a tidy message with one download button. They do not need an account, an app, or any idea what we are.

Or just grab a link

Prefer to send it yourself? Copy the link and paste it into WhatsApp, a text, or your own email. Add a password if it is something you would rather not have floating about.

See what has been picked up

Every transfer you have sent, in one list, with a clear tick next to the ones that have been downloaded. No more scrolling back through sent items wondering.

We tell you the moment it lands

You get an email the second they download it. That is one fewer chasing phone call, and one fewer "sorry, did you send that?" on a Friday afternoon.

Pull it back if you need to

Sent the wrong version? Delete the transfer and the link dies instantly. Files expire on their own too, so old client data does not sit around forever.

Who uses it

Built for people with a business to run, not an IT department.

Every trade hits the same wall eventually: the file is too big for email. Here is who we see most often.

Builders & tradespeople

Site photos, drone footage, snagging videos and scanned drawings sent straight to the client or architect — without WhatsApp crushing the quality.

Accountants & bookkeepers

Send year-end accounts and payroll files with a password on them. Far safer than an email attachment, and you can see exactly when the client opened it.

Photographers & videographers

Deliver a full wedding gallery or a 4K edit in one link. No compression, no ten-part zip files, no awkward "did you get it?" phone call.

Estate & letting agents

Property walkthrough videos, EPCs and inventory packs off to solicitors and landlords in seconds, with a link that expires when you want it to.

Designers & print shops

Send print-ready artwork and layered source files to the printer exactly as you saved them. What you upload is what they open.

Solicitors & consultants

Bundles, reports and case files that are too big to email, protected by a password and stored on UK infrastructure.

Simple, honest pricing.

Start free and stay free if that is all you need. Upgrade only when the files get bigger or you want them to stick around. No contracts, cancel whenever.

Why not just email it?

Because it will bounce. Again.

Most inboxes reject anything over 20MB. A single phone video can be three times that. Here is how the usual workarounds actually stack up.

What you need	Email attachment	WhatsApp	Vaulex
Send a large video or photo set	Bounces over ~20MB	Heavily compressed	Full quality, any size
Original file quality kept	Yes, if it fits	No — quality is stripped	Byte-for-byte identical
Password protect it	Not without extra software	No	One tick box
Know it was actually received	You have to chase	Two blue ticks, maybe	Email alert on download
Recipient needs an account	No	Yes, and your number	No — they just click
Suitable for client data	Sits in the inbox forever	On a personal phone	Expires automatically
