How much does it cost?
Your first month is free, with no card needed. After that it is £2.99 a month or £29.99 a year in the UK, €2.99 or €29.99 where the euro is the currency, and US$2.99 or US$29.99 everywhere else, with tax included, and you can cancel at any time.
Does it track when people open my emails?
No. There is no tracking pixel in any signature. Clicks on your signature's own links are counted, and that can be switched off on your dashboard.
What do recipients using Outlook see?
Current Outlook plays the animation unless animation effects are switched off in Windows; older versions show the first frame. Every design starts on its finished frame, so either way they see a complete signature.
Can the banner change without me reinstalling the signature?
Yes, with campaigns switched on. Your signature carries one banner slot that is filled when the email is opened, so a campaign you schedule appears under every email that shows it, including ones sent before it started (a mail app that has already shown an email may keep its copy). Campaigns have start and end dates and 3 priority levels.
