Find That Email

Name2email

➤ Gmail plugin
20 Dec 2022 have used it for around 100 contacts' emails. It seems to work well though still need to validate the emails. Also it's quite labour intensive to use it for a large number of contacts. Not a good solution to scale, but a good one to have in one's toolbox for one-off searches, straight in the Gmail interface.
Seamless.ai

Tested their email finding service in 2019 and was disappointed with results.

Email Deliverability
See also dedicated note: !b2b-sales/email-deliverability
Main tool for warming up an email:
lemwarm
With a new email (and domain!), there is a higher risk of your emails being marked as spam.
This kind of tool automates sending/receiving emails to/from your email address to build a reputation.

Not cheap though..
