What We Do

Enterprise-grade retention marketing, delivered boutique.

We don't do social. We don't do paid ads. We do one thing — email and SMS — and we do it at a level most agencies can't touch.

Retention Strategy

Full-cycle strategy built on data, not guesswork. We stack-rank initiatives with the IPE framework and predictive scenarios so the roadmap matches revenue impact, not noise.

Email & SMS Execution

Campaign calendars, flow architecture, creative direction, and rigorous QA — executed with the precision your brand deserves.

Deliverability Audits

Our comprehensive Find & Fix audit ensures your messages reach the inbox. We diagnose and resolve deliverability issues that silently destroy revenue.

Platform Migrations

Deep mastery of Klaviyo, Customer.io, Hubspot, Braze, Salesforce Marketing Cloud, and more. We advise on and handle migrations, and unlock platform capabilities most agencies miss.

Testimonials

Teams that care about retention trust Essence of Email.

Here’s what partners say after working with us.

Director of Ecommerce · Misook

We've been extremely impressed with the results so far from our new SMS efforts. Our agency, Essence of Email, helped us get launched in only a couple of days. Within two weeks we were already generating over $45 per text with our campaigns. We're now focused on using PostScript's automations to grow our lists and continuing to send highly engaging messages to our customers. We've seen an unbelievable 10x difference between clickthrough rates on SMS versus our existing marketing messages!

Our email marketing results with Essence of Email have been fantastic. The team is a pleasure to work with and they truly care about delivering results. From the high quality design that matches our brand to connecting with our customers, we have seen much better results over the big marketing companies we had worked with previously. We highly recommend them.

I really enjoy working with my team with Essence of Email. I think they really understand and connect with our brand and our customers and they handle everything, from planning, execution, and scheduling. They understand our core customer and the messaging and artwork that appeals to them. They are also competitive like I am and enjoy sharing and watching stats to see how our campaigns and flows are performing, try new things, etc. I feel like I can openly share ideas and let them figure out how those ideas can fit into our schedule or our existing flows. They are positive and eager to take on new challenges and help. I really have the best team!

Meet the Team

Principal-led. Not delegated to a junior team.

When you work with Essence of Email, you're working directly with me — not a revolving door of account managers. I've spent over a decade in the trenches of eCommerce retention marketing, leading strategy for 450+ brands from scrappy DTC startups to IR500 retailers.

We intentionally cap our client roster so every account gets the strategic depth it deserves. Your retention marketing program is too important to hand off to a junior team.

This isn't a volume play — it's a craft. I publish State of Email reports, contribute thought leadership across industry publications and podcasts, and bring proprietary insights from across our entire portfolio to every engagement.
