You have introduced a huge number of unnecessary points of failure.

• Google must still be operational
• Google must still be offering the "send in the future" service, which they could discontinue at any time
• Google must decide not to close your account for inactivity
• Google servers must not be damaged and result in data loss
• Google servers must not be hacked and result in theft of your wallet (and a huge amount of time for an attacker to bruteforce your BIP38 password, and nothing you can do in the meantime to stop them or secure the coins)
• Google employees must all be honest and also not try to bruteforce your BIP38 password
• The receiving email provider must still be operational
• You must still have access to the receiving email provider account
• They also must not have decided to close your account for any reason
