Email signature blocks are must haves.
Important contact information must be included when sending or receiving an email message – it authenticates you.
Name, business, telephone, mobile phone, business name, address, logos, IM, SKYPE, vCard, website, social media connections, quotes, sig tags, Emoticons, legal disclaimers, virus checked messages…that’s a lot of YOU.
Email exchanges can stretch for several “pages” and including your full signature with each reply can turn email chats voluminous.
Include your full-on, BIG “this is me” signature the first time.
After that, who you are.
