Magento 2 Integration

Why is there no Magento 2 integration. This seems ridiculous for a company like ConstantContact to not put a little bit of money to having an extension for Magento 2. It would make Magento store owners like myself be more accepting of Constant Contact. I have been with Constant Contact for over 10 years and now after upgrading our store to Magento 2 might have to change to another provider if this extension is not in the works.
