How a marriage ministry stopped sending 8,500 people the same email.

Their work isn't generic marriage advice. They help couples build a shared mission. A weekly huddle for the over-committed pair drowning in work and kids. Listening prayer for the wife who wants her husband to lead spiritually and the husband who has no idea how. A completely different conversation for the couple on their second marriage, blending two families and a lot of old hurt.

By early 2026, around 8,500 people were on Spark's email list, and every one of them got the same broadcast. The diagnostic instinct that made Spark's in-person work land didn't exist in their email or on their website. A newlywed with no kids and a remarried couple in crisis opened the same welcome email and got the same call to action.

Mike said it best on our first call. “When I have people in person, I can read them, I can ask, I can flow. I haven't been able to transfer that online yet.” Spark knew its people arrived in at least seven distinct situations. The marketing treated them as one.

And these couples were not strangers to what Mike calls the drift. Once we started asking, they told us in their own words: going through the motions, living separate lives under the same roof, no energy left for each other at the end of the day. Spark had a real answer for each of those couples. It just had no way to ask the question at scale.

So we built Spark a diagnostic that works the way Mike does. A short survey on the site asks a few low-friction questions: what brought them here, where they are in their marriage, whether they have kids, and what has been showing up in the relationship lately. From those answers, RightMessage sorts each couple into one of seven personas, syncs the result into Kit, and changes what they see next. The headline, the offer, the welcome email, the whole path now matches the couple reading it.

Behind that sits an offer engine. Instead of pushing everyone toward the same product, Kit calculates each subscriber's next best offer and RightMessage serves the right call to action on the site. Purchase history always wins over guesswork, so nobody gets pitched something they already own. We also rebuilt Spark's email as evergreen sequences with dynamic calls to action, so the personalization runs on its own instead of waiting on Mike to schedule another broadcast. Around 21 sequences now cover welcome, pitch, post-purchase, and re-engagement.
