Rate limits on incoming alerts?

Is there any limit to how many incoming alerts a global ruleset can handle?

Hi David,

Our global ruleset would have a limit of approximately 120 calls/minute per global ruleset.

What happens to emails coming in beyond 120 per minute? Are they ignored? Processed later?

Hi David,

For email integrations the email message transfer agent will respond with success status (SMTP code 250) in response to all email, but will begin dropping emails without any change in the response code if the rate limit is exceeded.

Please let me know if this is helpful or you have additional questions.
