Don’t talk down to people. I think this should be obvious. But looking at the email offers I get, clearly it isn’t. Don’t tell people, “Not buying this product would be idiotic!” or “Only a fool doesn’t understand the value in this service.” This whole email marketing strategy relies on you making people understand the value they can get from you. And sometimes that means making people see the downsides of not buying. But you can do that in a friendly, respectful way.
Messages which require online action work better in email than DM (direct message on social media), whereas calls-to-action to text to a shortcode or download a mobile app work fine within a DM. RFM and response analysis will indicate channel preference since customers with a preference for specific online channels will be more responsive in them and will make more purchases online.
People buy when they feel that they have good reasons to do so. So, you need a strong value proposition (=great reasons for buying what you sell). If you don’t have it, you can’t be able to give people good reasons for buying. If you don’t know what—specifically—would make people see value in your offer, how could your email marketing (or any marketing) be effective?
It’s true that your customers do want to hear from you. The fact you have a regular email marketing campaign is one of the magic elements boosting your ROI. But there’s such a thing as overkill. Once you come off a great campaign it’s tempting to run the same campaign again in an attempt to get the same results. The chances are you’re going to get diminishing returns.
Open and click-through rates (CTRs): Knowing who are engaged customers (those who open most emails and end up making purchases) versus inactive customers (who haven’t opened any emails in months) can be invaluable. Marketing campaigns announcing a new product should absolutely include those engaged customers, while re-engagement campaigns can be created to try and entice the inactive customers.
Now, work out the kinds of email communications which are appropriate and manageable for your brand. Newsletters? Generalised product promotions? Targeted product promotions? Order confirmation emails? Product reminders? All or a combination of the above? Work out what’s appropriate for you, and work out what’s appropriate for your personified customers, at each stage of their journey.
