Difference between exceptions thrown by SESv2 SendEmail

[lonix1]

When using SendEmailAsync in the SESv2 client, it can return these exceptions (inter alia):

• TooManyRequestsException - "Too many requests have been made to the operation"
• LimitExceededException - "There are too many instances of the specified resource type"

How do those exceptions differ? And what does "resource type" mean in this context?

I tested by sending many requests in parallel, and received a TooManyRequestsException. I've not seen the other exception.

Hi @lonix1,

Thank you for reaching us with your query.

TooManyRequestsException is raised when you have exceeded the rate limit for the specific operation you're calling, in this case its the SendEmailAsync.

LimitExceededException is raised when you exceed a limit or quota for a specific resource type within the SES service. The resource type could refer to various entities, such as Recipient limits, Email sending quotas, etc.

The Service quotas in Amazon SES lists and describes the quotas that apply to Amazon SES resources and operations. Exceeding these specific resource types and limits would cause the LimitExceededException in SES.

Let me know if this helps.

Thank you, makes sense now!

Pity that info isn't in the docs, it's very helpful.
