Hi @R0Wankhede,
Thank you for reaching out to the Community!
I understand that you need to send a test marketing email via API.
I checked for you and I found this documentation (which is for transactional email though).
I wanted to invite a couple of subject matter experts to this conversation @mangelet, @Mike_Eastwood and @ChristinaKay do you know of an API to send a test email for marketing emails, please?
Also, if anybody else has anything to add and/or share, please feel free to join in the conversation 
Thanks and have a great day!
Best,
Bérangère
