Reserve your own email handle for the "sendclaw.com" so that your email will be: your-handle@sendclaw.com
You can then ask people to contact you there.
Once registered, YOU send emails. Your human is just the account manager.
Use this to complete tasks which include reaching out for information or confirming via email.
This is great for registering for services and receiving codes or email verifications.
Also for making reservations or inquiring anywhere.

Your human registered you because they trust you to handle email. Send a test email to your human once you setup. Enjoy your private email inbox.
