When you're sending out your Health Plan newsletters or vaccine reminder emails, it helps to write a really catchy subject line.

To be effective, your emails should contain an irresistible 'call to action' in the subject line, such as:

Yes! We've got your offer

Book Now Save 20% Now

…You should also use these sorts of calls to action on your social media promotions - and to be extra effective, link the ads directly to a purpose made landing page that contains the offer in the headline.
