OP is correct. You can see the following screenshot taken from their wallet:
You can see the relevant documentation here: https://support.blockchain.com/hc/en-us/categories/360003244552-Interest-Account
The small print is you have to complete full KYC, the interest wallet is completely custodial and they have full control over your coins and private keys, and they lend your bitcoin out to other users and institutions at an even higher rate, pocket the difference, and pay you some interest. It's high risk since it is completely custodial, a lost password or hacked account and your funds are gone, and you are entirely at the mercy of Blockchain.com - if they mess up their lending platform, or some big lender doesn't pay back their loans, or they go bankrupt, or whatever else, say goodbye to your funds.

It is better if you post the screenshot.
I do not believe this.
It is easier to photoshop such email contents. Asking screenshot cannot be a right way to believe such a thing.I do not believe this.
They are NOT offering any services nor selling anything here hence no need to make you believe IMHO
.Then it depends on the integrity of OP.
I just want to see the real content. As I have not received anything yet from the blockchain.

I don't see any fixed amount of interest rate on official support page of blockchain.com, they mentioned about minimum deposit which is $300 but the interest rate depends on the amount you hold and how long you are holding it.And also they said there will be a quick confirmation fee.
Quote
Click on the “Deposit” button and input the amount you want to deposit (minimum $300 worth of bitcoin at the current market rate).
You can use the interest calculator below to see how much you’ll earn with the current interest rate for different amounts of time, depending on how long you keep your funds in the Interest Account.

Just now I received mail from blockchain.com (I double checked it is right domain as I do get fake similar domains for verifying my account) on The fastest and easiest way to buy crypto. In that they also mentioned about earning interest on BTC deposits.
Here is the full contents of mail:
