Ease of Use:
You don’t have to actually create/buy bunch of email addresses over and over again and replace them with new ones. Once your catchall email is setup you can get GSA SER tool to randomly take billion of aliases out of “%Spinfile-names.dat%” in combination with random numbers “%random-65-95%” making each email to be different every time.
%firstname.lastname@example.org can generate billions of different email combinations like: email@example.com, firstname.lastname@example.org, email@example.com etc.
You just have to duplicate your GSA SER projects without changing your catchall emails ever. Hence preventing you from tedious task of uploading and deleting disposable emails over and over again.
Sounds More Credible:
Emails on custom domains always seem more credible as compare to the emails created on free-based servers like (hotmail, yahoo etc.). Some platforms don’t allow registration using free emails which makes you miss the potential of creating more powerful backlinks.
Furthermore, most of the services create disposable emails on auto-generated large-character aliases that don’t sound natural. They prefer this to ensure their availability due to immense competition. For e.g.
However, catchall emails on your own domains lets you chose the short-character aliases with proper combination of genuine human names making it sound more natural and credible.
Affordable than Disposable Emails
Catchall Emails are much affordable. It actually means billions of emails with more affordable pricing than bunch of disposable emails.
