Email remains the highest-return channel most businesses have, and it's the one most often left to decay. The decay is rarely creative. It's a domain that was never authenticated properly, a list padded with addresses that haven't engaged in three years, and a template that breaks in the client a third of the audience actually uses.
So we start with the plumbing. SPF, DKIM and DMARC configured and aligned, sending domain and subdomain strategy set, reputation checked, and inbox placement tested for real rather than assumed. Then the list: inactive segments suppressed, addresses validated, and re-engagement run before anyone gets removed — because sending to people who never open is what teaches a provider to filter you.
Only then does the sending programme matter. Templates built on a modular system that renders correctly in Outlook and in dark mode, segmentation so content is relevant to who receives it, and the automated flows that consistently outperform broadcasts — welcome, abandoned cart, post-purchase, replenishment, win-back. Reporting is framed on revenue per recipient and list health, because open rates became an unreliable metric the moment mail privacy protection started pre-loading images.
