Gravity form does not send notification even when resend the notification says "notifications were sent successfully"

Hi, my gravity form does not send notification even when resend the notification says “notifications were sent successfully”.

smtp has been set up properly and its working fine before.

Here what I have done so far

  • Setting smtp mail and did the mail test trough the plug in (successful sending email test)
  • Created a notification with a simple content (no html dan pdf attachment) and resend the notification. The Result : The mail successfully sent.
  • Created a notification with html code in it along with pdf of submission attached to be resent the notification. The result : The Notes says with green “Notifications were resent successfully.” but no email received to my email

Can someone help me with this?

Is this due to

email provider ?
smtp plug in ?
or gravity form plug in itself

Please let me know any solution
