⭐⭐⭐⭐⭐ “Nikita is super easy to work with, he’s always full of ideas, and the email designs are amazing. He helped turn our Klaviyo emails from unprofitable to being one of the biggest revenue drivers for our e-commerce business.” - Allison Klein, CMO @ Dingo Boots I'm Nikita, with over 8+ years of email & sms experience my specialty is helping brands turn email into a consistent profitable channel that helps bring in more than 25% of revenue to the business every month. With deep knowledge in Klaviyo, Omnisend, Sendlane, and Shopify I'm confident I can help your business achieve revenue goals that you aspire to. 𝗠𝘆 𝗕𝗿𝗲𝗮𝗱 & 𝗕𝘂𝘁𝘁𝗲𝗿: 1. Software Proficiency (Klaviyo, Omnisend, Sendlane, ActiveCampaign) I don’t just navigate these platforms; I engineer them. My expertise goes beyond basic setup. I build robust, scalable email marketing infrastructures across all major ESPs. Whether you are on Klaviyo, Sendlane, or Shopify, I make sure to use the tools to their full capability to turn your retention into a revenue rocket. 2. Email Design, Copywriting, & Setup This is where brand identity meets sales psychology. I create emails that do more than look good, but also convert. By fusing compelling copy with intentional design, I build templates that stop the scroll and drive action. From the technical implementation to the final pixel, I ensure every email feels like a seamless extension of your brand. 3. Email Flow/Automation & Campaign Management I build the "silent salesman" that works while you sleep. By implementing complex, behavior-based triggers, for Welcome series, Abandoned Carts, and Win-backs, I ensure no lead slips through the cracks. I manage the full customer lifecycle, turning sporadic traffic into a consistent, automated revenue stream that requires minimal manual input from you. 4. Email Strategy Strategy is the difference between sending emails and building a business. I look at the big picture, aligning your email roadmap with your acquisition channels (like Paid Ads and Social). My goal is to create a holistic retention ecosystem that nurtures customers for the long haul, increasing Customer Lifetime Value (CLV) and Customer Repeat Purchase Rate (CRPR) rather than just chasing a quick click. 5. A/B Testing & Segmentation Stop guessing and start optimizing. I treat your list as a data mine, using granular segmentation to ensure the right message hits the right person. I pair this precision with a scientific approach to testing, constantly iterating on subject lines, send times, and content to validate what actually drives revenue, removing gut-feel from the equation. 6. Deliverability & Getting Out Of Spam The best email in the world is useless if it lands in the Junk folder. I act as the guardian of your sender reputation. By managing technical protocols (SPF, DKIM, DMARC) and monitoring domain health, I ensure your emails bypass spam filters. If you are currently blacklisted, I have the expertise and protocols to fix it; if you are healthy, I make sure it stays that way. So if you're ready to make your email channel run like a profitable well oiled machine that consistently generates revenue without lifting a finger? I'm your guy. Send me an invite and lets see how we can make it rain dolla bills for your business!
