[2019] Oops

Okay so I have forgotten the email address for an alt I created at the start if this month, cant even tell you the in game name only part of it but you cant do a search on high scores with only a part of an account name so that's no use, the only info I have is that I bought a bond on the 4th of this month so I could go to Wintertodt now I want to go back on it, but cant remember details, I have an authenticator set up but again no useful info, anyone have any idea or is this account lost until I remember the email address?

Although I may have used runelite with the account and if I did then there will be screenshots of me leveling up that may have the account name on them which will help, cant check till I'm home though

Edit - I now have the name of the account, so is this anymore useful?
