- WiseStamp is great for email signatures. Free version is decent but not fantastic, paid version is worth it though ($5 a month). Integrates with Gmail, and also allows multiple signatures for different accounts. I have been using it for about 2.5 years now and can definitely recommend it.
I get asked about my email signature at least once per week - people think it's fantastic. My theory is that having my photo in my signature makes people more likely to respond to me because they see that I'm a real person, not just a random email address. I teach a lot of workshops on networking, and I highly encourage everyone to get their own WiseStamp signature to help direct potential new contacts toward the information online that they want to present. It helps control how people learn about you right off the bat, rather than having them rely on Googling you. It's one of my most-used tools in my arsenal.
Email Signature is now really mandatory and must have for every blogger because google is giving more importance to the Author's Bio. So, we should have a bio which is detailed and let the user connect to us easily with trust factor. This wisestamp works fine when it comes to giving a proper email signature and other signature which are needed in the author bio.
