Acquisition is sexy but retention is where smart teams focus.

There’s more to life (growth) than paid social.

Giving your money to Meta in exchange for new customers is addictive, but it’s getting more expensive by the day. Of course, with shiny creative, stellar landing pages and a little algorithm leveraging, you might feel like you’re moving in the right direction.

But then the gong sounds! You realise your CPAs are climbing, your Average Order Value is decreasing and profitability is taking a hit.

Your marketing needs to be more efficient.

You need customers upgrading to the penthouse suite, ordering Champagne and waxing lyrical to their friends about the extraordinary experience.

That is where the art of Retention Marketing takes centre stage.

Retention marketing works to help increase your Lifetime Value and build loyalty, giving you what you need to scale profitably. As enamoured customers start recommending you, the whole system gets more efficient and your LTV:CAC ratio gets better and better.

When you choose to hire Wild Side, you gain access to a team of experienced growth and creative strategists. We don’t just send emails, we craft experiences and orchestrate campaigns to build deeper relationships with your customers and capture additional revenue.

You’ll be sat at the bar with a martini in hand before you know it.
