I am currently trying out Amazon SES. It says my current limits are:

  Quote

50,000 emails per 24-hour period

14 emails per second

Would the second value conflict with sending out newsletters via IPS’ bulk mail feature?

And wasn’t there once a setting to use separate services for bulk mail vs. transactional mails? I can’t find that anymore. 

You can probably use the BULK_MAILS_PER_CYCLE constant to define how many emails are processed per cycle. It's not exactly what you were asking for, but it should work;)

 

 

You can also try out the following app to get rid of SMTP and use the AWS SES API for better performance and less impact on your server.

I use this, works very well. 

I know this product and will probably purchase it when my SES test is successful. 

But does it do anything differently in regards to the sending limits? Because that was the question.

I don't think the SES sending limits change. The app uses the SES API vs SMTP so there is not SMTP relay. 

Bulk mail is sent via task, not sure how many at a time. You can set that cycle amount:

If your web host or email provider cannot handle sending many emails at once, you can optionally add the following line to your constants.php to set a number to process per bulk mail cycle. In this example we are setting it to 25 per task cycle.

define ( 'BULK_MAILS_PER_CYCLE', 25 );
