unfortunately I agree with Peter, that universities deletes your e-mail when You resign the affiliation, that's why I normally use Gmail, i don't want to take the risk :)

it is also good to use ORCID :)

Yes, I do agree with both Ukleja and Peter, even in some Institutes the corporate email ids of the tenure track position holders are not made. We have to use gmail or other similar websites.

It is essential to use your formal or institutional email in all of your daily academic activities.

I also recommend use of your personal email address for paper publications so far you have access to it.

If access to your personal email is not as fast as your institutio

If access to your personal email is not as fast as your institutional email. You may switch to choice later.

I believe it is ethical to use either your personal email or academic email for publications depending on convenience

The academic/institutional email looks more professional, but your personal email will stay with you even if you leave the institute and you will be contacted easily
