Online customer service always comes…with "clear your cache."
Online customer service always comes back the same way first: it's on your end. Clear your Cache, restart...have your checked your internet connection? Really? What's the "internet"?? Perhaps I should try hitting my computer on the side a few times and see if that helps.
When someone tells you the platform has worked well for years and suddenly and consistently is not performing, try looking at your end and determining what the disconnecting issues might be.

Hi Spike,
Thanks for the feedback, and I’m sorry this has been frustrating.
You’ve been using MailBigFile successfully for a number of years, so if something that has worked reliably for that long suddenly stops behaving properly, that’s something we want to look into. Reading your review, I also think our initial response could have been better. We should have spent more time understanding the problem before jumping to the usual troubleshooting.
We haven’t made any recent changes to the underlying architecture, and we haven’t had anyone else reporting similar issues, which makes it even more important for us to investigate properly and understand what might be causing the issue on your account.
I can see there is already an open support case. We will continue looking into this with our developers and I will get back to you tomorrow.
Regards,
Steve
Code Verification issue
You corrected the mailing issue and I was finally able to send my file, though I still had issues with the To and From fill in. This time the Verification Code arrived and my Friend has successfully received her file.
I love the simplicity of using Big Mail.

Thanks so much for the great review and for the kind words about the simplicity of MailBigFile, we really appreciate it.
I’m glad we were able to get the mailing issue sorted and that your friend successfully received the file in the end. Sorry to hear you still had some trouble with the To and From fields along the way.
If you’re happy to do so, please feel free to email us with a bit more detail about what you experienced. Feedback like this really helps us improve the service.
Thanks again for taking the time to leave a review.

Hi Spencer,
Thanks for your feedback and I’m really sorry you had such a frustrating experience resetting your password. Our password reset system normally works by entering your email address and receiving a new password automatically, but I can see from your messages that things didn’t go smoothly this time.
You contacted our support team and we attempted to reset the password for you manually, but unfortunately the email was sent to the wrong address which meant you didn’t receive the updated details. I appreciate how annoying that must have been.
We’ve now reviewed the case internally and made sure your login is fully sorted. We’ve also tightened up our internal process to make sure this doesn’t happen again. If you still need any help at all, please contact us directly and I’ll make sure you’re looked after straight away.
Thanks again for taking the time to let us know.
Steve.
Brilliant company
Mailbigfile was a tremendously useful tool while I was still working, with never a hiccup. Despite termination complications on my behalf, communication with the company was extremely quick and efficient…All credit to them

Hi Jenny,
Thanks very much for the positive review. It was great to read your comments. Most people only tend to post when something has gone wrong, so it’s genuinely appreciated when someone takes the time to share a good experience.
I’m pleased to hear MailBigFile worked well for you.
Thanks again for taking the time.
Cheers,
Steve
Genuinely awful
Absolute doodoo. Having to use it to submit my portfolio to a university and it can't even load in a 5.7mb zip file. Ridiculous.

Hi Arthur,
We’re sorry to hear you’ve experienced issues with our service. Please don’t hesitate to reach out to us at support@mailbigfile.com, and we’ll do our best to resolve the problem promptly.
Our service allows file uploads of up to 100GB, so a 5MB file shouldn’t pose any challenges. When you contact us, could you kindly include the university’s name for reference? This will help us assist you more effectively.
* Are you trying to upload files to De Montfort University? If so, could you please confirm that you’re using the correct link: https://www.mailbigfile.com/dmuac? *
We’d like to mention that several other students from De Montfort University have contacted us about this issue. If the University has indeed sent the incorrect link in their email, the correct link to use is provided above. We kindly ask that you consider removing your negative review, as this matter is beyond our control.
Thank you,
The MailBigFile Team

This is an utter scam of a company
This is an utter scam of a company. I subscribed for one year pro use. One year later I get a message from them saying I have now resubscribed at a much higher price. I did not authorise them to make my subscription a recurring one, and they did not tell me in advance that a payment would be taken or how much it would be. They have used payment details from a year previously and taken money from my account without authorisation. There is no easy way to cancel an account on their website and minimal/no information about an account is available online. Avoid this dishonest and underhand company at all costs!!!

We are not a Trustpilot customer, so we do not actively monitor these reviews. However, I wanted to follow up on your review. I see that you also contacted our support team simultaneously, and we promptly processed a full refund for you within 2 hours of your inquiry.
Feel free to let me know if there’s anything else I can assist you with.

It's not letting me cancel my membership and won't let me log in. Feel that it's a bit of a scam. I keep resetting my password and I still can't access it!

Very pleased - would recommend
MailBigFile worked very well for gathering photographic and video entries for a large competition.
We found it easy to use and when we did have questions, the support team were very helpful and quick to reply.
Happy to recommend to others and will use again in the future.

We've been using MBF for 10+ years
We've been using MBF for, I think, 10 years now (maybe more) and we couldn't function as a business without it.
We use several Gigabit+ connections and have tested the "other file transfer systems" and MBF is by far and away the fastest download and upload so not only the most reliable but the fastest too!
It's a serious business tool, if you move big files MBF is the one to have.

Wouldn't want to go elsewhere
I have subscribed to MailBigFile for 8 years or so now and would not consider going anywhere else. The price is incredibly low, service is excellent and the portal has never failed us. Why wouldn't you?

Mail Big File Rocks....
We're a video production company so we regularly send large video files to clients and they in turn send us gigabytes of stock footage. We've used MailBigFile for years. Never had a problem and we love our branded Business account.

Thanks for your review Michael! Good to hear you are enjoying our services!
Works seamlessly and the customer service is the best!
I have been using MBF for over five years, and I have never had a problem with any uploads - including some very unwieldy files to multiple recipients.
Recently, I had to reach out to customer service to ask about upgrading my account to Business Account so that others could upload files to share with me.
I have rarely had such friendly, helpful and knowledgeable customer service reps. There was no waiting in an endless holding loop, no 'pleas press #5 to reach . . .' or 'let me transfer you to the that department': I immediately reached someone who solved my answered my inquiry within minutes.
Can definitely recommend MBF for your large file transfers.

Time to move on...
I've been using the paid version of MailBigFile for quite a while now and I'm going to move to someone else. It really is 50/50 whether a file uploads or not, and I can't afford that level of unreliability. I've used other sites (I'm not going to name names) and they don't seem to have a problem, but MBF consistently stalls during uploads and I have to start again, which is incredibly frustrating. When their sole function is to upload files and they can't reliably do that then it's time to move on.

Complete fail at the first hurdle
Download link took me to the Mailbigfile website, but the download button just resulted in the error message :
"This XML file does not appear to have any style information associated with it. The document tree is shown below."
Then there was a paragraph of xml indicating some form of access denial error
