Frequently Asked Questions

System requirements

  • Mac OSX: 10.15 or 11
  • MS Windows: 10

How do I contact you?
Please send an email to support@sendplus.com and we will respond as soon as possible.

I can’t seem to login
Ensure that your login and password are correct; they will be the same as your Adstream credentials. If you have forgotten your password, then click on the forgot password link, and a password reset link will be sent to you. Check proxy server settings (if you happen to use a proxy server). Check if you need an activated SSO.

Do I need to open any firewall ports?
The following ports should be open on your firewall for optimal Sendplus operation:

  • HOST: api.sendplus.com - TCP port 80, TCP port 443
  • HOST: xmpp.sendplus.com - TCP port 5222″

How fast can I send files?
Sendplus will utilize around 80% of your available bandwidth in accelerated mode. It won’t monopolize all your connection so you can carry on sending emails and browsing the internet at the same time.

Does my recipient need to download Sendplus to retrieve the files?
No, once registered, your recipient can download the files you have sent them by logging into the Sendplus website. However, there are some advantages to downloading and installing the desktop client.

To download from the website your recipient must wait for you to finish uploading the file, with the download client they can start downloading the files immediately without waiting for the upload to complete. Only desktop client downloads take advantage of the network acceleration, so the client will download that content much faster.

Do I need any browser plugins?
No browser plugins are required to send or receive content. Files can be downloaded via the desktop application.

How can I track my file transfer?
The desktop client and the web application will show you if the recipient has started downloading the content, how much of it they have downloaded, and how long it will take to download the files. It will also show if the recipient has cancelled or paused the download. The transfer monitor will show a large green tick when the transfer is complete, and the recipient has finished downloading the content.

What platforms (OS) do you support?

  • Windows 10
  • Mac OSX: 10.14 or 10.15

Can I send multiple files or folder structures?
Yes, Sendplus will accept any number of files as a payload. It will also allow you to drop complete folder structures onto the client to send and maintain that structure on delivery. This will enable users to send packaged media formats like RED or XDCAM.

How secure are my transfers?
The data sent via Sendplus is 256bit encrypted, and cached and encrypted on our servers. All Sendplus infrastructure is ISO27001 compliant and has been audited for MPAA and CDSA compliance.

Checking network connection
The best way to check your available bandwidth is with the inbuilt diagnostics tool. Or, go to www.speedtest.net, this will tell you how much bandwidth you have available for Sendplus to use.
