ALM OTA has a send email functionality which can be leveraged for sending emails, but I dont know if that can be scheduled in any way.
Below is the example from OTA API reference 
    Sub AttachFileAndMail()
    ' This example shows how to check if a defect has attachments,
    ' how to add attachments to a defect, and how to mail
    ' all the attachments of a given defect.
        Dim attachFact As AttachmentFactory
        Dim theAttachment As Attachment
        Dim attachList As List
        Dim BugFact As BugFactory
        Dim theBug As Bug
        Dim AttachmentList() As Variant
        Dim HasAttachs As Boolean
    On Error GoTo AttachFileAndMailErr
    ' Get an arbitrary defect for this example.
    ' To find a particular defect, use
    ' BugFactory.FindSimilarBugs or Bug.FindSimilarBugs.
        'tdc is the global TDConnection object.
        Set BugFact = tdc.BugFactory
        Set theBug = BugFact.Item(1)
    '------------------------------------------------------
    ' Use Bug.Attachments to get the attachment
    ' factory for the defect.
        Set attachFact = theBug.Attachments
    ' For demonstration purposes, print the
    ' names of existing attachments.
        Set attachList = attachFact.NewList('''')
        For Each theAttachment In attachList
            Debug.Print ''The Attachment.FileName is '' _
                & theAttachment.FileName
        Next
     'For this example, guarantee that there are
    ' attachments to an email by attaching files if
    ' necessary.
     'To run the example, ensure that your workstation has files:
    ' ''D:temperr.log'' and ''D:tempoutput.txt.''
        HasAttachs = theBug.HasAttachment
        If HasAttachs Then Debug.Print vbCrLf & ''----------------------------------''
        If Not HasAttachs Then
            Set theAttachment = attachFact.AddItem(Null)
            theAttachment.FileName = ''C:temperr.log''
            theAttachment.Type = TDATT_FILE
            theAttachment.Post
    '-------------------------------------------------------------
    ' Use AttachmentFactory.AddItem to create the new project entry.
            Set theAttachment = attachFact.AddItem(Null)
            theAttachment.FileName = ''C:tempoutput.txt''
            theAttachment.Type = TDATT_FILE
            theAttachment.Post
        End If
    ' Populate a variant array of server file names
    ' for use in the SendMail method.
        Set attachList = attachFact.NewList('''')
        'Count starts at one and Variant Array size
        ' starts at zero (but see Option Base in the Visual
        ' Basic help), so array size is Count minus one.
        ReDim Preserve AttachmentList(attachList.Count - 1)
        Dim i%
        i = LBound(AttachmentList)
    '-------------------------------------------------------------
    ' Use Attachment.ServerFileName to specify the attachment.
        For Each theAttachment In attachList
            AttachmentList(i) = theAttachment.ServerFileName
            i = i + 1
        Next
        Debug.Print vbCrLf & ''----------------------------------''
    ' Array is populated. Let's see what we have:
        Dim fName
        For Each fName In AttachmentList
            Debug.Print ''The AttachmentList element is '' & fName
        Next
    '-------------------------------------------------------------
    ' Use TDConnection.SendMail to
    ' send the attachments.
        tdc.SendMail ''steves,alex_qc'', tdc.UserName, _
            ''TestMail TDConnection.SendMail with attachments'', _
            ''TDConnection.SendMail: This is a test'', AttachmentList
    Exit Sub
    AttachFileAndMailErr:
    ErrHandler err, ''AttachFileAndMail''
    End Sub
also if you want to schedule it then you will have to either use task scheduler or softwares like jenkins which can execute code for you.
We had the same issue and to resolve it we have create a simple HTML website which can generate the reports at runti
