Game companies in particular block these services. Anywhere where a company frequently has to ban accounts for abuse usually eventually blocks forwarding services.
I exclusively use alias emails and have found the down side. If you use an alias email for each site you visit (let’s say an online shop that is ran by Shopify) there is an extremely high chance your purchase will be flagged (fuck you Shopify) as a fraudulent account. I am constantly being flagged on sites with Shopify back ends for fraud. It really sucks when your hoppy (FPV Drones) is mainly ran by Shopify sites.
P.S. There is no one to help resolve these issues with Shopify as they don’t have a customer support unless you’re a customer and the store owners are either dumb on how to help or just plain lazy.
Ebay blocks me everytime. I checkout as guest and usually when I try to order from the same email again, it is indefinitely suspended for reasons they cannot explain to me.
Here is what you should have done. Get a cheap ass domain and signup for Zoho's email service which is totally free.
I bought a cheap domain from them. The price is very reasonable. Then AI proceeded to make use of their free email suite service, which requires your custom domain (hence the cheap domain purchase).
The free email suite gives you give free email accounts.
Each email account in turn has unlimited alias feature. I use their email accounts each for different uses (work, social media, etc). For only 10$ a year, I do not suffer from spam, promotions and shit. I use a dedicated alias for cookiebeggars and registration mofos who won't let you see their content. Another alias for a pathetic spamming shopping site etc. They have a mail client for all platforms so no issue with accessibility. The email has calendar, bookmarking, note taking and other small managerial stuff too. I recomend this approach.
It's never too late. Give it a try. With the 10 free emails you can compartmentalize pretty easily. I pay for Proton Unlimited so it comes with SimpleLogin Premium, so if you want to give it a spin, it doesn't cost anything.
