Technical setup of eSputnik and integrations for email marketing

We are looking for a specialist for the technical setup of eSputnik for a single business project.

— assist with the basic structure of email communication;
— integrate eSputnik with the existing Apex Drive bot / automation;
— set up the transfer of applications and contacts into the system;
— check the correctness of the entire connection.

Important:

It would be a plus:
— experience working with Apex Drive / integrations;
— experience in technical setup of email systems;
— understanding of CRM and automations.
