Business cards are still important when you network and socialize. They might not be as important as they were 10 years ago, they are still relevant and must have for anyone looking to make personal and business connections. Plus, there's something about having business cards that gives you that small feeling of accomplishments.
Have you ever considered the effectiveness of your business cards? Do people actually use them to follow up?
Well I thought about it. How do I know if they work? I can't be asking everyone who emails me, "Where did you get my email?" I needed a way to track emails coming from my business cards without complicating things. So the solution was really easy: use a unique, simple email address for my business cards.
So I've created an easy email address with one of my primary domains and that's what I use now on my personal cards; and for my business cards I do the same trick with the business domain. So every time someone follows up with me using my email address from my business card I know my business cards are not useless - they actually work.
Thanks to GSuite, I was able to setup a filter and a label for those incoming emails. Now, those emails are color-coded, never hit my spam box, and are marked as important.
When you reply and begin dialog the transition is seamless and people don't notice the difference in the email as I reply with my regular email address.
Bonus tip: Your business card holder is not a magazine for an AK-47. So don't just spray the crowd with your business cards. Be selective. Ask for a business card before offering your own.
