A disposable address is for a short use, such as receiving a verification email from a website. It is not a good choice for every account.
Do not use it for password recovery
Use an email address you control long term for banking, important accounts, purchases or any account you may need to recover later. A temporary address can close, and an expected email may not arrive.
Check the website before buying
Enter the website that will send the email code. See the addresses and prices available for that website after sign-in. Then enter your chosen address on the website and watch the corresponding order for a message.
Temporary is not anonymous
SpiderOTP processes account and order information. The email provider and the website you contact may also process your information. A disposable address does not guarantee anonymity.
