FAQs
How does the AI work?
The AI is trained on email (opens, clicks, orders), behavioural (product views, carts, checkouts), and business (product performance, inventory level) data. With this data, it determines optimal send times (8AM - 8PM) window and content for every subscriber. It does not generate or design email content and does not override brand or creative controls.
Does the AI generate content or override brand controls?
The AI does not generate or design email content and does not override brand or creative controls. We think the main focus for the marketing team should be to build beautiful, creative that will resonate with the customer. The AI does the heavy lifting when it comes to choosing the right audience and sending the emails.
Can we still create one-off campaigns for big launches?
Yes, you can still create one-off campaigns and time them the way you want, this system does not prevent you from doing business as usual work.
How can we know that it is performing well?
You will access a report that shows you how the AI CRM Marketer is performing vs manual campaigns. We set up a control group that serves as a baseline for comparison.
