Great article on how to find anyone's email address. Looking at the WHOIS is a great tip.
One of your article links is going to an old domain - metricsparrow.com/toolkit/email-permutator/.
Last week, ahrefs.com switched their email permutator link to us because:
- The copy buttons on the old domain above are broken
- Our permutator has rare, common, and all permutations for ease of use
- We have an email permutation video tutorial + Q & A section
- Our page has been ranked no. 2 by Google for the last few months.
Would you be open to linking to us instead?
