Email Discovery tools?

have to reach out to influencers but only have limited info. sometimes their twitter or instagram. sometimes have their linkedin. often times, i have first / last name + company .....

what's the most reliable way of getting emails from this info ... at least 50-60% of the time ?

What i use to find emails is hunter.io.

Works very good for companies. If you need more than 100 searches per day, use the tor browser.

For 1 Time Use , You Can use temp mail service.
