We took the data of over 5 million companies and wanted to figure out the most common email patterns used by companies by their headcount. Hereโ€™s what we found out.

As we predicted, smaller companies tend to use just {first} only. Whatโ€™s interesting is that mid-size companies like using {f}{last} and changes to {first}.{last} when you get to the larger companies.
