- Weekly shipping cadence, reviewed every Monday
- Coordinated with SMS, lifecycle, and paid channels
- Adjusted live based on previous-week performance

Brand-grade design, built into a system.
Email design is a craft, not a template choice. We build a modular design system per client — colours, type, components — so every send looks like the brand and reads at thumbnail size on a phone in the inbox.
- Brand-aligned design system per client
- Modular component library for fast, consistent builds
- Mobile-first design tested across major clients
- Dark mode, accessibility, and rendering edge cases handled

We don't blast. Every campaign and flow targets a specific cohort defined by recency, engagement, RFM, or purchase behaviour. Suppression rules protect deliverability while precision lifts conversion.
- Dynamic segments built on engagement and RFM
- Win-back, replenishment, VIP, churn-risk cohorts
- Suppression logic to protect sender reputation
- Quarterly segment audits + cleanup

How we built a $1M+ email and SMS engine for Avantera Health.
Avantera came to us with an inconsistent email program, basic flows, and revenue leaking from email. Six months later: $1M+ in attributed email and SMS revenue, 50+ A/B tests shipped, doubled sending volume without hurting deliverability. Email became their highest-leverage retention channel.
“The quality and timeliness of deliverables are most impressive. The team has always been on time and has used ClickUp to organize tasks. The team's quality work and strong account manager have stood out.”
Zack P. Head of Growth, Avantera Health

“Optimite offers competitive pricing for the clients. They emphasize on receiving good value for cost, quality work, timely delivery, and flexibility in handling urgent requests, making them a strong choice for email marketing services.”

The questions buyers ask before they hire us for email work.
Both. You can hire us for email only and get a deeply specialized email program. Or you can hire us for the full retention system (email plus SMS, lifecycle, loyalty, list growth, subscription) and the channels reinforce each other. Most clients start with email and expand from there.
Klaviyo is our primary platform and we're a Master Platinum Partner. We also work with Postscript, Attentive, HubSpot, Mailchimp, Omnisend, and most other major ESPs. If you're already on Klaviyo, we're a perfect fit. If you're considering a migration, we can advise on the move during the discovery call.
Once the agreement is signed, onboarding starts within 24 hours. First quick wins live within 30 days. Full email program optimized and running by Day 60.
Both. We have an in-house team of email strategists, copywriters, designers, and Klaviyo experts. Strategy, copy, design, build, QA, send, and reporting are all handled by us. You don't need to staff anything internally.
Vertical specialization, in-house design depth, and full-system thinking. We've shipped 500+ email programs across six verticals so the playbook is real. Our design team builds emails that hold up against your brand standards. And we think about email as part of a connected retention system, not as a standalone channel running in isolation.
