Leaving Mailchimp for Sarbacane/Sendinblue: out of the box connectors?

Hello,

In the past we've been using Mailchimp a lot since the price/quality ratio was excellent and the SugarChimp connector provides an excellent experience. 

Since some of our customers are now reluctant to use a non-EU based solution, we're looking for alternatives. 

Sugar Market is much too expensive (and powerful) for a lot of scenarios. 

We've identified Sendinblue and Sarbacane as good solutions, but neither seem to have an out of the box connector other than Zapier which defeats the purpose as it's hosted outside the EU AFAIK. Sarbacane offers a limited OOTB plugin for Salesforce. 

We've done some preliminary work for Sendinblue but it's not reusable easily and we are not yet sure that there is an actual market for that. 

Has any partner developed a ready-to-use connector?

Cheers,

Damien
