If you've done your campaign prep (Note: You must be logged into Phrasee to view this article) for your dynamic broadcast campaign, then you're ready to launch.

Phrasee's dynamic optimization works by feeding back engagement data in real time to our magnificent AI. Then, that AI will dynamically (hence the name) adjust how many people receive each variant.

To do this, we need to give your subscribers time to interact with your email. So for your broadcast sends, we'll need to use Responsys' throttling feature.

You'll need to calculate (ew, math?) the rate at which your message should be sent. This rate allows Phrasee the time it needs to optimize your language.

Phrasee would like as much time as possible to get the best results for your experiment. So the longer you allow, the better your results!
​
Calculate the send rate by picking the number of hours over which you want to deploy your experiment and using that to divide your audience.

For this example, we are going to use 6 hours and an audience of 1,000,000. Simply divide your audience of 1,000,000 by 6, as in the below example:

1,000,000 / 6 = 166,667

Launch rate limit = 166,667 messages per hour

When you do this calculation for your audience, simply use your total audience size and desired number of hours. Once you have your number, enter it in the Limit launch rate to box. You'll find this at the bottom of your Launch campaign window.

You can then continue scheduling your campaign as you normally would. Make sure you take your send time length into consideration when you decide when your campaign should start.

Now, get out there and optimize! (Don't forget to write! You know how we worry.)
