Mass cold email outreach results/data-oriented questions

For your email signature, do people respond better when you're the founder, co-founder, coo, etc...?

For your email name, do people respond better when its your [email protected], or [email protected]?

And how about [email protected] vs [email protected]?

My thoughts:
I feel like it does not matter, but will effect the recipients thoughts of how big the company is. Not sure if good or bad. Will put founder if founder.
I also feel like what ever looks aesthetically pleasing will work best. If I have my long first name and long last name @company.com, it would look weird.
If I have nickname and long lastname @company.com, it would also look weird.
If its a short first and short first name @company.com it would look good.
If its a full name @company.com it would look good and better than nickname @company.com

Will putting full name last name @company.com will add more transparency and legitimacy to email and should do it even if it looks like [email protected] ???

Thoughts?



Thoughts formatted here:

founder vs co-founder reply rates

[email protected] vs [email protected] vs [email protected] vs [email protected] reply rates

Names doesn't really matters but better to use names rather than roles and its also your reputation on that domain and how your customers reacting with emails your sending.

Good luck

All the matter is the content of the email and what you are pushing with the cold email. [email protected] is fine.
