Additional tool for GSA

Hello, Thanks for reading my thread.

I have some SEO tools like GSA

I'm searching about additional service that needs on GSA.
like E-mail, links etc..

First, what kind of E-mail service are required for GSA?

Second, How to make a quality link database?

Second, is scrapebox are good for link building?

Thank you for your respond.

You can get both email accounts and link lists here on the BHW marketplace:

IMO Scrapebox is not good for link building, unless you only want to build links on very simple platforms.
