Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
Could you please forward a receipt from FastSpring.com if you have managed to save it by any chance so we can locate your account? If you have used a card to purchase, you can also share the last 4 digits 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.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
It looks like the purchase was made from your account linked to email ID n**@g*********
You can log in using that ID at https://rankmath.com/my-account/
Alternatively, you can reset your password from the same page as well.
We can also merge your accounts if you prefer. We just need your preferred email ID for that and we will keep only that one active.
Once you are logged in, please check this guide on how to activate your PRO license on your website: https://rankmath.com/kb/how-to-upgrade-to-rank-math-pro/
Hope that helps and do let us know if you want us to proceed with the account merge.
Hello,
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
Thank you.
