ConvertKit‘s most recent upgrade includes, countdown timers, Twitter embeds, easy landing page social sharing and sequence enhancements.
With countdown timers directly added to your newsletters directly via ConvertKit, with no integrations required, you can add a sense of urgency to your mailings.
You can indicate the end date & time for your promotion, and when that end-time is reached, the timer will be automatically overlaid with a message of your choosing to indicate that it has expired.
You can also now embed Tweets directly in ConvertKit emails and landing pages. Find out how here.
