Attach .VCF file to outgoing email

[Cecil]

Hello,

I would like to attach a .vcf file to all of my new, outgoing emails. I
have a signature set up that is different than my V-card as it has a
disclaimer in it and different information on me than the card.

Is there a way to automatically attach a file to outgoing messages, not
replies, without it showing up in the body of the email?

Thanks in advance!
Cecil
