Sticky Digital

Sticky Digital is a retention marketing agency that specializes in email and SMS for direct-to-consumer (DTC) ecommerce brands. Based in San Diego, California, the agency was founded in 2020 and has grown to a team of 10-49 employees. It holds a 4.6 rating on Semrush and is a Klaviyo Platinum Partner, a credential that signals deep technical expertise on one of the most popular ecommerce marketing platforms. The agency was also voted Retention Marketing Agency of the Year, though the specific awarding body is not disclosed.

What sets Sticky Digital apart is its laser focus on retention over acquisition. While many email agencies optimize for open rates and click-throughs, Sticky Digital measures success by customer lifetime value, repeat purchase rate, and the percentage of total revenue coming from existing customers. This philosophy is embedded in every campaign and flow they build. The agency works exclusively with DTC brands in beauty, wellness, food & beverage, and apparel, and it does not take on clients outside these verticals. This narrow focus allows the team to develop repeatable playbooks for common lifecycle scenarios, from welcome series to winback flows.

The agency's service offering covers the full retention stack: marketing automation, email marketing, SMS marketing, segmentation, deliverability management, and lifecycle flow design. They don't do batch-and-blast campaigns. Instead, every send is tied to a customer's position in their lifecycle, their purchase history, and the most likely trigger for a repeat purchase. Sticky Digital reports that clients typically attribute 35-50% of total store revenue to email within six months of engagement. This is not because they send more volume, but because each message is strategically timed and personalized.

Pricing is project-based with a budget range of $2,500 to $10,000 per project. The agency works with small, mid, and enterprise-level businesses, and project duration is flexible. Geographic focus includes the United States, United Kingdom, and Canada. The agency communicates in English. Given the project-based pricing and the relatively small team, Sticky Digital is best suited for DTC brands that have a clear retention challenge and are ready to invest in a structured, data-driven approach.

Sticky Digital is ideal for DTC ecommerce brands that want to reduce their dependency on paid advertising platforms like Meta and Google. If your brand is already generating a meaningful number of repeat purchases but lacks a systematic retention engine, this agency can build the infrastructure to turn one-time buyers into loyal customers. it's less suitable for B2B companies, service businesses, or brands that are just starting out with no customer base to retain.

Overall, Sticky Digital is a well-positioned specialist agency for DTC ecommerce retention. Its exclusive focus, platform expertise, and revenue-driven approach make it a strong choice for brands that are serious about owning their customer relationships. The lack of public client reviews is a minor concern, but the agency's clear methodology and reported results suggest a high level of competence in its niche.
