Thank you for reaching out to the Community!
That is a great question! We do offer Solution Provider Certification if you would be interested in becoming a business partner. Please send an email to social_support(at)constantcontact(dot)com with some contact information if this is something that you would be interested in.
Otherwise, we do not offer a training program to become certified in using Constant Contact. That said, we do have a wealth of information that can help you learn our program. All of this information can be found in our Knowledge Base center Here!
Thanks and have a great weekend!
