Social media may be the young whippersnapper nipping at email’s heels, but the content king of the inbox still holds sway in social influence, according to a study by SocialTwist. Over an 18-month period, SocialTwist monitored 119 referral campaigns from leading brands and companies. The results showed a significant advantage to email’s ability to convert new customers compared to Facebook and Twitter.
Newsletters are long-haul engagement. They serve as check-ins with your subscribers, as well as offering generalised engagement points. Newsletters are a way of both driving and maintaining engagement – at worst they serve as a reminder of the relationship the recipient has with a brand, but usually, they do a lot more. Provide as many engagement points/links as you can within your newsletters, and you'll be surprised at what crops up!
As long as you are keeping track of your client’s most recent appointment times, this kind of automated reminder email is quite easy to set up. Use a custom date field to record when their last appointment time was, then set up the email to be sent 3 months later (or whatever your recurring schedule is) to remind them that they are due for their next appointment.

Personas provide a multi-dimensional method of targeting. They’re based, as the name suggests, on a projected persona for each customer ‘type’. Get it right, and personas can help you enormously in both predicting behaviour and personalising your communications. Personas are a powerful technique, and they’re increasingly used to improve the usability and customer centricity of communications.
When it comes to deciding how to craft that perfect subject line, there appears to be really only one area to avoid: the subject line of 60 to 70 characters. Marketers refer to this as the “dead zone” of subject length. According to research by Adestra, which tracked over 900 million emails for its report, there is no increase in either open rate or clickthroughs at this 60-to-70 character length of subject line.
