Module for CRM & Marketing automation for Drupal ecommerce

Hi All

I'm in charge of an ecommerce site made with Drupal. It is https://smart-r.fr

To develop the business I now need to step up with a solid tool for lanching email campaign :

- transactionnal emails

- emails based on purchase history

- newsletter based on our blog to be automaticcaly sent every 2 weeks

On the top of that, I'm a bit diasppointed about our ERP/CRM systems and we also plan to change it.

So my questions are the following :

- what is your feedback for an emailing/marketing automation tool able to do at min the 3 points I 've listed (we are a new startup with very small budget)

- what is your feedback about an ERP that works perfectly with drupal commerce and also able to provide CRM functionalities

Your answers will be very precious for us as we are investigating solutions and it is a bit difficult for us to find right answers

thanks the community !!
