Just to clear any confusion, you do know that bitcointalk is not associated with blockchain.com/.info, right? So this forum is not an official helpdesk. That being said, some people will try to help you out of pure goodwill, others might try to scam you (by asking about your walletid or sending you phishing links).

If you don't get an answer from a trustworthy person, it's probably best to limit yourself to blockchain's official helpdesk, eventough they're not that responsive (or so it seems).

A last piece of advice: switch to a decent wallet if/when you regain access to your account ASAP. Web wallets are one of the worst kinds of wallets...

If it is the blockchain.com wallet then go here:

If it is not blockchain.com then as ETFbitcoin said you will have to give more information before anyone here can help you.
Also, did you delete the email and then empty the trash folder or might it still be sitting in trash / deleted items?

That's very vague information. For starter, can you tell us what wallet do you use? By any chance, is it blockchain.com wallet?
