Awesome plugin!

If you are new to newsletter services or just want to switch to another platform with a free plan. Sendinblue free plan includes an unlimited number of contacts (email recipients) but you are limited to the number of 300 sends per day, in total a maximum of 9,300 sends per month. These numbers may seem low, however, I believe the majority of users do not need more for a start. Especially if their email list is based on their existing customers.
