I’m setting up a private app to use HubSpot as our transactional email provider. In addition to the private app in our production account, I also need to be able to send test emails from testing and local setups.

Is the testing aspect possible, in particular local testing?

- It sounds like [some support is required](https://community.hubspot.com/t5/APIs-Integrations/Transactional-Emails-in-Test-Portal/m-p/227780) in order to enable transactional emails. I need to be able to set “Transactional email” scope on a private app in developer test account.

- Are there IP allowlisting/registration requirements for single-send API? I’m hoping I’m just misunderstanding the “dedicated IP address” aspect, but I need to make sure as I won’t be able to register all possible local IP addresses that may be used for testing.

Hi, [@BjørnVårdal](https://community.hubspot.com/t5/user/viewprofilepage/user-id/447307) 👋 If you have access to Support, the fastest way to submit your request is to use the info found in this thread — [How to activate transactional email / single send API in the developer / test portal](https://community.hubspot.com/t5/APIs-Integrations/How-to-activate-transactional-email-single-send-API-in-the/m-p/516144/highlight/true#M48092).

Thanks, [@Jaycee\_Lewis](https://community.hubspot.com/t5/user/viewprofilepage/user-id/127074) !

Just one question about the available functionality. The thread you linked to says to include a “a non-exhaustive list of email addresses to which you plan to send transactional email tests” in the request. In my setup, I need to use dynamically generated email address, e.g. to test new account creations. If some email address restriction is required, is it possible to restrict it by domain?
