Sometimes the signup bonus doesn't apply automatically. It's a known issue and it's fixable.
If you signed up through my link but didn't see the $1,000 credit in your account, reach out to support@hyperagent.com and send them my link ID: https://hyperagent.com/refer/UL9AD5EE
This has worked for others, so don't worry. This only applies to signups to paid plans.
