The Senders™ Card is caller ID for your email. In other words, it appears at the bottom of personal email messages you receive and shows you some additional information about the person who emailed you. We do not modify or enhance any outgoing email messages.
Senders is not a signature for your own emails and will not appear in emails you send to people, unless they also have a Senders account. If you are a free user, a brief watermark will appear in replies, notifying your contacts that you are using Senders. Neither the watermark nor the Card appear in replies for premium users.
You can see how your Card will appear to other Senders users by searching for it from the Senders home page or by going to your user dashboard.
