Am I required to use SES to get out of the sandbox?

Question

Greetings,

We are attempting to host a CRM on an EC2 instance, but I discovered in a previous attempt that AWS blocks outgoing mail ports by default, so I applied twice for an increase in our sending limit but our use case was rejected both times without explanation (presumably because we were not using SES).

My questions is am I required to use SES in order to send mail on AWS?

Accepted Answer

Hi,

You don't need to rely on SES to send email out of AWS EC2 or Lambda, by default outbound email is restricted but you can get that access removed.

But it is a best practice to use AWS SES. If you are using SES you should run it in production mode for your application because SES Sandbox is only for testing purposes.

Hello.

If you are using AWS, it is easy to set up Amazon SES.  
However, it is not absolutely necessary to have Amazon SES to send emails.  
For example, you can build a mail server on EC2, or use a mail server you already have on-premise.  
In rare cases, an EC2 IP address may be registered in the block list and fail to send out emails, so basically we recommend using Amazon SES or similar.
