Application Level DoS

  • Check if Application has Invite Functionality
  • Try sending Invites to Invalid Email Accounts
  • Try to find Email Service Provider such as AWS SES , Hubspot , Campaign Monitor

Note You can find Email Service Provider by checking Email Headers

Once you have the Email Service Provider, Check there Hard Bounce Limits. Here are the limits for some of them:

  • Hubspot Hard bounces: HubSpot's hard bounce limit is 5%. For reference, many ISPs prefer bounce rates to be under 2%.
  • AWS SES: The rate of SES ranges from first 2-5% then 5-10%

Impact: Once the Hard Bounce Limits are reached, Email Service Provider will block the Company which means, No Emails would be sent to the Users !
