1. What is the AI Email Agent?

The AI Email Agent is a lifecycle campaign automation tool powered by Bespoke and integrated with Polar. It personalizes the delivery of your existing Klaviyo email campaigns to increase revenue per subscriber by dynamically choosing which campaign to send, when to send it, and to whom—based on first-party behavioral data from the Polar Pixel.


2. What’s the value proposition?

  • +10% expected lift in Klaviyo campaign revenue

  • Fully leverages your brand’s own creative—no AI-generated emails

  • Maintains your brand identity and control

  • Reduces pressure on email teams to constantly build/send newsletters

  • Increases reuse of evergreen and high-performing content

  • Adds always-on experimentation and testing (subject lines, send time, cadence)


3. How does it work technically?

  • You continue to create emails in Klaviyo and leave them in Draft

  • Each campaign is turned into a flow via a custom Bespoke trigger

  • The AI determines who receives what, when, and with what subject line

  • It pulls data from Klaviyo and Polar (behavior, purchase history, inventory, etc.)

  • AI matches creatives to individual profiles based on engagement, product views, and LTV


4. How is performance measured?

  • A/B test via Control vs. Optimized groups

  • Bespoke uses reinforcement learning with a 10% random exploration bucket to continue learning

  • Metrics tracked:

    • Revenue per email sent

    • Revenue per subscriber

    • LTV impact

    • Unsubscribes (to safeguard long-term value)


5. What’s the workflow for my team?

  • Continue to build emails in Klaviyo as templates or campaigns

  • No need to schedule sends—the AI takes over delivery logic

  • Weekly: add 3–4 new creatives to the system

  • Monthly/quarterly: prune outdated content (e.g., expired sales or out-of-stock products)


6. How is inventory handled?

  • Polar feeds inventory data from Shopify into the AI

  • Bespoke disables creatives referencing out-of-stock products

  • You can tag creative types (e.g., new collection, evergreen, influencer, sale)


7. Can I still run manual campaigns?
Yes. AI campaigns run in parallel. You can still manually send high-priority or urgent newsletters (e.g., sale announcements) and exclude AI sends for that day.


8. What’s the ideal segmentation setup?

  • AI operates on all mailable profiles

  • No manual segmentation needed: the model personalizes on a 1:1 profile level

  • Advanced use cases: exclude trade/partner lists, manage engagement suppression


9. What kind of testing options exist?

  • Full AI rollout

  • 50/50 split: half AI, half manual

  • Simulated control (e.g., static send policy like “Mon-Wed-Fri at 8am”)


10. How is creative uploaded?

  • Bespoke can automatically convert templates into flows

  • You can batch import historical campaigns to build the creative catalog

  • A tagging interface helps you manage seasonal and evergreen creative


11. What kind of support is included?

  • Onboarding is white-glove: kickoff call, Slack support, help importing emails

  • Weekly reviews with the Bespoke team (Khaled or team) during the first 90 days

  • Live access to performance dashboards in both Polar and Bespoke


12. What is the pricing model?

  • $1,000/month flat for the first 3 months (trial & AI training phase)

  • Full money-back guarantee in the first month

  • After trial: pricing depends on list size and email volume, typically $2K–$4K/month


13. What results have other brands seen?

  • Doen: +10% increase in Klaviyo campaign revenue, projected +$1.8M in 2025

  • Albion Fit: reduced campaign stress and improved evergreen content reuse

  • Organic Olivia: expected 10% lift, plus major team workflow efficiencies


14. Does this work with SMS or Meta audiences?
Not yet. The AI Agent is currently email-only but is designed to expand into CRM orchestration, including SMS, Meta audiences, and push notifications in the future.


15. Who owns the data and how secure is this?

  • All email content and logic stays within your Klaviyo account

  • Polar securely pipes first-party data to Klaviyo for AI training

  • Bespoke only reads what it needs and complies with strict security protocols

  • You maintain 100% control and can stop the AI agent anytime
