Moving from sendgrid legacy to new subscription
Bought a new subscription from AWS marketplace but was never able to setup/configure the new subscription. The "click here to setup your account" always failed on the sso login, and nobody was able to resolve this. Ended up buying a new subscription from outside AWS marketplace and migrating all our templates etc.
