A proTimer countdown timer is an excellent timer for your promotions. You can use it for websites and emails.
With the integration with MailerLite you may set up offers based on the individual sign-up date of your subscribers (perfect for use with autoresponders).
For instance, if you are selling software with a 10-day trial period, you may want to offer a discount on the 10th day with MailerLite's autoresponder.
A proTimer countdown in the autoresponder's email will display how long the offer lasts for each subscriber. And another proTimer countdown on your website will automatically close the offer after the specified time.
