Around here, we are big fans of services like Mailchimp for monthly newsletters and great email templates.
Movable Ink is a similar service but with a twist.
They have some real time apps to embed in your emails which can be used for sales, fundraisers, etc.
Countdown timers, live tweets and local maps are some of the apps you can put into your emails.
Here are some examples of case studies:
They have a free version where the Movable Ink brand is part of your email and is more for personal use.
They have a pay as you go plan where they promise to charge only on what they call a True CPM basis. This means, you only pay for the emails that are actually opened which can save money.
Do you have any ideas on how you can use this in ministry?
