There are 2 methods to attach files to the letter.

1st method:

  • Press the button "Attach files".


  • In the new opened window choose files You need to attach. Remember that You can choose more than one file if these are in the same directory.



  • Click "Open" button and all files will be added as the attachment, and will be placed below the message writing field and shown as icons of files.
  • If You want to add additional files, click "Attach more files" and repeat steps, mentioned above.
  • To delete any file, hover Your mouse over the icon of a file and in the drop down menu click on "Delete".



Remember, that You can add many files to one letter.

The maximum size of sent letters including attachments - 50MB.

If You will try to add files, which total size exceeds allowed size for attachments, You will see a notification about it and these files will not be added.

Attention! Inbox Mail service allows You to send and receive emails with attachments with total size - 50MB, but, when sending email with large attachments, we recommend to find out their limits on the size of incoming messages - it can be smaller than size of Your sent letter, for example, only 30MB. In this case Your letter will not be delivered.

If You need to send a file that is larger than 50MB, or another e-mail service set lower limits on the size of incoming messages, we recommend to use Inbox Files product - it allows to send link to download files, which are up to 1.5 GB. More about Inbox Files - here.
