SecurelySend is a free service to send large files in email. You can send files of up to 200 MB for free using this free file sending service. This is really handy if you are trying to send large file to someone, but your email client does not lets you attach such a large file.
To use SecurelySend, you start by creating a free account. After that, you can compose your message online that you want to send to your recipient. Then you can upload the file that you want to send with your message. Once the file has been uploaded, you can send the message that the recipient will receive in his/her mailbox. There will be a link to the attachment in that email, and your recipient can just click on that to download the file that you shared.
SecurelySend is definitely extremely easy to use. It took me just a few seconds to create my online account with SecurelySend. After that, it was very intuitive to create email message, and attach file.
SecurelySend has some additional features that it offers in premium accounts. You can get a read receipt for email, and also password protect your file in premium account. I really wish the feature of password protect was available in free account as well.
