I generally recommend having a different email for each case so that it is as easy as possible to sort messages. not only spam emails but all incoming messages
Maybe you know from my previous posts that I applied this solution and have multiple
offertyww@gmail.com, ofertyww1..., ofertyww9... and so on addresses.
Anyways even such an amount of emails didn't save me from spam and overwhelming.
Every time when one email was flooded with spam I created another one and tried to sort the promotions and bounties from the best once to the worst and put them into different emails.
Finally, all of these addresses were so flooded with spam that to be honest, they are useless. My info was sold and with time the amounts of spam only keep growing until a moment that I was not able to find nothing more if sent to these addresses.
