Hello, I'm new here and need help

I have been following this website for a while, but I haven't studied it in depth. I am very happy to be one of them and promote communication and learning.
Now I am facing a problem and I don't know who to ask for help, so I post here and hope that enthusiastic netizens can help me solve it.
My email was hacked, and the emails sent by my customers went to the advertising mailbox. For this reason, I upgraded the security of my email, but this is not the worst. What's worse is that he registered an email very similar to mine to defraud my customers. What should I do now? Is there any good way for me to disable his email?

What you like it if it was possible for someone to disable your email?

Your only option is to report to your local police authorities and see what they advise to do next. Its a technology misuese fraud issue if someone already hacked your email, and is still causing you problems. Make sure you are sure that you've locked down your passwords, and etc with regards to your email.

if you have a website post a sticky message somewhere visible (on the homepage most likely) telling your customers that your email was hacked and that all new communications should be done through [whichever new email] you'll have set up in the meantime from thereon. Also tell them to blacklist every email that impersonates you or your business and to report it to whoever: ISP, email provider, etc)

I know that his doesn't directly answer your question, but it can alleviate the problem and salvage your customers' trust in your business

Thank you for your message, you are absolutely right, it happened so suddenly that I was too angry to think about the problem rationally.

+1 for this,
and send an email to all of your customers, notifying them about the incident,
do the same if you have any social media accounts/pages,

you can't completely stop such fraud/scam,
there's always a fair probability that someone would do the same with your website/domain, email, social networks, etc... once you gain some traffic,
your best bet would be to fight it back, legally by reporting each of them & directly by communicating with your users (customers)
