Question about the dot trick for email

Let's say I create 10 Instagram accounts all on different proxies and I use the dot trick with my main email address that is linked to my home IP. How can I verify my email address on all accounts which are created on different proxy IPs when the confirmation link is always sent to my email that is on the home IP?

Does anyone have a workaround or solution to this?

just copy the confirmation email link and paste it to browser with your instagram ip.
