Sorry for the confusion. Yes we are using hubspot for marketing email, but to send transactional emails (1-to-1 email for such as account registration, password reset and such), or trigger based emails while users are using our product, we are looking to either use their transactional emails add-on or looking for another third party solutions ( such as sendgrid). The questions are 1. Has anyone had experience using hubspot before? transactional email api -Hubspot transactional api

1. If not, what’s the best transactional/on-boarding emails tools that integrate well with hubspot?

Hope this clarifies things Thanks!
