Your brand is your baby, so when it comes to email marketing, you're likely very careful about how you design, write and send. But is being too careful limiting your ability to create dynamic emails that personalise content and drive extra sales?

If you're not familiar with the dynamic product block feature in Klaviyo, or you're hesitant to use it, trust us, you're missing out. The whole idea is to let the email fill itself:

What makes these blocks so useful? Here are three ways to put them to work.

Building a campaign about your newest releases? You've got full freedom to pick the products. But have you thought about your flows? Set-and-forget flows like a welcome series often include products to inspire purchases. If you're not updating them every time new stock arrives (which is hugely time-consuming), your audience misses out, and that new release doesn't land the way you hoped. Dynamic blocks solve it:

Some customers know what they want the moment they land. Others need inspiration, and that's where recommended product blocks shine. In flows, instead of lengthy manual edits every time a product falls out of favour, the block pre-populates from what's actually selling best on your site over a window you set, three days or thirty:

The block ranks by live sales data, so the number one really is your number one at that moment.

An often-overlooked use: recommendations based on what a customer has bought before. Split a flow like your winback or post-purchase into streams based on their most recent purchase, then show only categories similar to what they've ordered:

However you use it, this tool is powerful for influencing customers to spend more and driving your store to new heights.

The best product block is the one you never have to touch again, because it already knows what to show.
