In OP's defense I would always recommend one single email for a smaller attack surface. As long as you practice strong pass phrase security and storage, keep tabs on your privacy policies and change your password regularly, you shouldn't need to worry about a breach on YOUR end. THEIR end, the server-side or back-end, is what you need to be worried about. Is my password safe in their database? Are they using strong cryptographic hashing methods? Are they negligent with past and present data? Weigh your options. I recommend using email masking provided by Blur, the private email they give you can be used to generate an infinite amount of secure aliases. They can be used individually for each sign-up to track ads and separate your identity, but most of all, it keeps you safe from attackers leveraging your email to find other services you might use. This is known as obfuscating your identity. It's a very basic and simple form of securing your data; therefore you can tell what service sells your data or which gives your email to other parties, and that email won't be connected to your real email. Your reply-to email remains as the masked email. The best part? It's 100% free and anonymous. I believe even th3j3573r used/uses it.

Thanks for the reply. I have never heard of Blur and from your explanation, it seems to be the right email service I am looking for. I haven't came across an email service that provides masking and/or tell us what services are selling my data. I will look into it and consider using it near the future. Thanks!
