In 2011 I wrote about WiseStamp as a way to give emails sent from a browser a richer signature. My thought was that a block containing only a name and phone number says little about who you are or where to learn more. Links to a website or relevant social profile could make it more useful.
WiseStamp still exists, but the old browser plugin, supported webmail services and automatically changing social updates are not a reliable description of today's product. Check current documentation if you want to try it. You can also start with the signature function in your own email program.
What does the recipient need?
A good business signature answers three simple questions: who is writing, on behalf of which organization, and how can I reply or learn more? A name, role and suitable contact channel are often enough. Add a website or relevant profile if it helps. A row of every network where you ever made an account makes the choice harder instead.
Consider the context. A private note does not need the same signature as a customer email. If you write in several roles, create separate versions. Occasionally check that links work, job titles are correct and an image does not dominate the message. People read email on small screens and with different settings.
Do not turn it into an advert
A promotion, quote or live update under every message can distract from the conversation. Ask whether it helps the recipient of this particular email. I would temper my original enthusiasm for automatic updates. A signature works when it makes contact easier, not when it becomes longer than the email above it.
