VBA Cancel send email sent by Gmail - ms-access

Question

I know that Google Gmail was a functionality to cancel the sent email within 30 seconds.
As I'm using this code to send emails from an access database, and via gmail, I would like to know if there's a way to use that functionality to prevent sending an email for mistake?
Sub SendEmail_Click()
Dim NewMail As CDO.Message
Set NewMail = New CDO.Message
'Enable SSL Authentication
NewMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = True
'Make SMTP authentication Enabled=true (1)
NewMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
'Set the SMTP server and port Details
'To get these details you can get on Settings Page of your Gmail Account
NewMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.gmail.com"
NewMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
NewMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
'Set your credentials of your Gmail Account
NewMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusername") = "mysite#gmail.com"
NewMail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "mypassword7"
'Update the configuration fields
NewMail.Configuration.Fields.Update
'Set All Email Properties
With NewMail
Dim strPath As String
strPath = ".mysite/wp-content/uploads/2017/07/myimage.png"
.subject = "this is the subject"
.From = "<mail#mysite.com>"
.To = Me.EMAIL
'.CC = ""
'.BCC = ""
.HTMLBody = "This is my message body"
.AddAttachment "https://mysite/temp/contacts.vcf"
End With
NewMail.Send
MsgBox ("This email was sent!")
'Set the NewMail Variable to Nothing
Set NewMail = Nothing
End Sub
