Looking for platform for creating alt emails

Hello, i'm looking for platform or any way to create alt emails i want to create like 5-10emails max every 1 month (it's np to delete the previous one) but it's to the same platform and every 1 month i have to do 10 emails and it's kinda annoying already i would like to find a way to do with alt emai.
Thanks

update: would be good if it's like different domains (avoiding getting some mass ban or something)
