Question about PGP

Hi,

I’m starting to use PGP on my emails. It is not hard, but it’s not easy either. I only have a few contacts that encrypt emails, but I think it’s also useful/nice to sign emails with your key, even when they are not encrypted. But I have a question about this:

When you want to send an unencrypted but signed email, should you also send your public key?

Thanks
