Maternity brands have the most predictable customer journey in eCommerce. Nine months. Three trimesters. Every need mapped in advance.

Your customer is the hero — an expecting parent navigating pregnancy with a thousand decisions to make. What's safe? What's necessary? What's worth the money? They need a guide who understands the journey and shows up with the right product at the right moment.

Here's the problem: most maternity brands treat their email list like a general eCommerce audience. Same campaigns to everyone. No trimester segmentation. No due-date-based automation. A woman in her first trimester gets the same email as someone about to deliver. That's not helpful — it's irrelevant. And irrelevant emails get ignored.

You have a plan for her. A properly built email program tracks the pregnancy journey and delivers exactly what she needs at each stage. First trimester: morning sickness remedies, belly butter, prenatal vitamins. Second trimester: maternity wear, nursery planning, registry. Third trimester: hospital bag essentials, postpartum recovery, newborn must-haves. Post-birth: baby care, breastfeeding support, sleep solutions. As a Klaviyo Gold Partner, we build these trimester-based email systems that follow the customer from first test to first birthday — turning a one-time buyer into a customer for years.
