Sometimes low-hanging fruit is as easy as it looks. Personalizing emails, as well as segmenting them—a marketing technique that teases out your subscriber list to send relevant emails to specific subscribers—can offer significant returns. Segmenting emails allows you to target specific groups of subscribers, which leads to substantial increases in click-through rate.
Their email marketing strategy and plan was to optimise their email subject lines because this was the first place that their customers would engage with. To do this, they used an AI generating subject line tool called Phrasee. There are plenty of increasingly sophisticated AIs out there which can do this kind of thing. Phrasee worked for Dominos because it capitalises upon being specific to brand voice, and is optimised to drive action.
For example, I can safely share that I listen to a lot of music, and I’m almost fanatic about sound quality. I might listen to an album with poor sound quality once, but I probably won’t go back to it. And to be clear, 95%+ of new recorded music has what I consider poor sound quality (due to an absurd standard of perceived loudness, which takes away natural dynamic range from the sound). That said, I’m not a hi-fidelity sound geek. I’m perfectly happy with my high-end studio monitors—I don’t buy $1,000 power cables, $5,000 CD-players, or $20,000 loudspeakers capable of playing back sounds too high for dogs to hear.
Edit. Even editors need editors. When you're working on your publishing calendar, leave plenty of time for the editing and revision process. Once you send a campaign, it goes straight to the inbox, and you can't go back and update it. Newsletters contain meaningful content, and sloppy ones reflect poorly on the companies who send them. Grammar and style are just as important for email as they are for websites and blogs.

What does your current email marketing performance look like? Analyse the performance of key metrics such as Open Rate, Click-through-Rate (CTR), Deliverability Rate, Unsubscribe Rate, ROI. What is working well and what isn’t. This can also be internally focused – for example, maybe it is taking a long time to create email content, or the creation process is inefficient.

A trigger can also be a passive customer behavior, such as not opening your last few emails, not logging in to use your service for a while, or downloading a product without downloading the tutorial or an important related resource. These types of drip campaigns can help re-engage customers who were moving through the customer lifecycle but have somehow gotten “stuck.”
Two particularly important groups for our purposes are customers with a one-time purchase and customers who have purchased multiple times. A customer is sometimes not considered to be loyal or repeat customer until they have purchased two to five times, in which case the single purchase segment is more akin to a warm prospect than a loyal customer.
