Hey jamasenr, thanks for your question! We differ from classic email marketing platform as we are a technology — you can actually use Reelevant with MailChimp for example. 
As for the personalization, it&#x27;s based on weather conditions, yes, but also on temperatures and device. At each opening of an email, we detect the recipient&#x27;s context to display the most relevant content in real time. 
Now, on top of this contextual analysis, we have also developed algorithms doing behavior analysis. The idea here is to identify unique engagement periods, so when you send an email to all your list, Reelevant will send them one by one, so they are delivered at the best time, for each recipient. So far we have been analyzing recipients behavior on each email (such as opens or clicks), we will soon go further but I can&#x27;t tell you more for now ;)
