I paid for a Google Domain and it came with unlimited emails forward, in fact you can literally redirect *@Domain.com to your normal email and you'll receive literally ANY email sent to your domain
Then you can set up Gmail so you're also able to reply from each address you need, it's a 3 steps process so it takes a bit to set up each time, but for receiving and signing up it's just perfect and superfast
