How to share login email between scenario in same feature file in appium java

We are doing Appium automation for native apps. I want to verify delivery address scenarios. In one feature file, I have multiple scenario for validating delivery address.

Scenario A : Register new credentials using email id and password, then add default delivery address. Scenario B : Use same email id (used in Scenario A) and verify add new address using some other .

We are using Serenity with Selenium /Java for Appium. Is there any method i can use that previous reg Scenario A email id in scenario B? I thought to maintain session only for this feature( I have other feature file of various functionalities too). But don’t know how to keep session maintain only for this feature file?
