Why interest in email marketing keeps rising
Four fundamental shifts in the digital landscape have turned email from a "necessary evil" into a strategic priority.
Owned channel
Unlike social media, your email list is an asset you own. You're not at the mercy of algorithms.
Privacy shifts
After iOS 14+ and the death of third-party cookies, paid ads are more expensive. Email becomes a priority.
AI personalisation
New tools enable hyper-personalisation at scale — something that used to require entire teams.
eCommerce growth
More and more DTC brands realise email is the core channel for repeat purchases and LTV.
