If you switch email providers for the same email address, you will need to create a new Interseller account since your email is now under a new provider. This means you won't be able to access your Interseller account after switching.
We can merge the two accounts into the same team and share all the sequences on the previous account with the new account. We can also transfer over the subscription to the new account so you can manage billing for the Interseller account you plan to use moving forward.
If you would like to access the data that was on your previous Interseller account, you can reach out to us via live chat or email at email@example.com so we can assist you further.
