Upon subscribing to a Mailgun plan via the GCP Marketplace, we were not provided with clear instructions on how to complete the onboarding process on the Mailgun platform. Guidance on the next steps following subscription activation would greatly improve the customer experience.

** Support Accessibility:
Although our subscription includes phone-based support, we have been unable to access this benefit. Currently, our only option is to submit support cases online, which appears to follow the same process as free-tier users without a defined response SLA. This has made it challenging to get timely assistance with our requests.

** Suggestion:
A smoother integration between GCP Marketplace subscriptions and Mailgun's support systems would help ensure that paying customers receive the level of service included in their plan from the outset.
