Where is the best place to get SSL certificates for personal mail?

Question

Email

Good afternoon everyone, the question arose, where is it better to get an SSL certificate for e-mail for private use - signature, S / MIME mail encryption.
Preferably free.
Used Comodo a long time ago . It seems that the service has not died, but I would like to expand the list.
