Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Can you please check the spam folders? See if Rank Math’s reset password URL was sent there.
If you still can’t see the email there, the PRO license must have mistakenly been bought using a different email address.
Can you please search and forward a receipt from FastSpring.com so we can locate your account and also confirm the purchase?
You can add a screenshot link using this tool in the sensitive data section

It is completely secure, and only our support staff has access to that section.
Looking forward to helping you.
Thank you.
