I love how helpful the support team is at Constant Contact! Thank you for working for our success. It would be very helpful (imperative to our business) to be able to add a custom hyperlink like a custom field. I don't want the whole link to show as it would now, but a simple ADD button where the link behind the add button is custom to each recipient. We used this feature in our previous email system because we are emailing our clients who already use our service when we want to use this feature.
