Teenva AI & Digital Ventures builds email personalization AI for B2B marketers, ecommerce brands, SaaS lifecycle teams, and agencies from Bangalore, India. At send time, each recipient gets personalized subject lines, opening lines, dynamic product or content blocks, and send-time scheduling—driven by CRM fields, browse/cart behavior, and LLM copy constrained by your templates—not one static blast with {FirstName} only.
Dynamic email at scale—with brand guardrails and suppression lists. Mail merge alone plateaus; Teenva combines rules + ML timing + governed LLM slots inside your ESP.
Build your AI solution with us
Email personalization AI—dynamic blocks, governed copy, and send-time ML inside your ESP.
What gets personalized
| Element | Personalization source | Example |
|---|---|---|
| Subject line | Industry, use case, recent activity | Company: cut AP time before March close |
| Preview text | Complements subject; A/B variants | Tied to same intent |
| Hero paragraph | LLM slot from CRM + RAG case study | One paragraph only—template surrounds it |
| Product block (ecommerce) | Recommendations, cart, browse | 3 SKUs in stock |
| Content block (B2B) | Vertical playbook from content generation | Fintech vs retail snippet |
| CTA label | Stage in funnel / lead score | Book demo vs Read guide |
| Send time | ML on opens/clicks per contact timezone | Tuesday 10:15 IST |
| Offer (scoped) | From churn prediction | Churn tier or loyalty segment |
Personalization runs per recipient at render/send—not one HTML file for everyone.
Feeds AI campaign manager journeys. Distinct from cart recovery. Hub: AI solutions.
How it works
| Layer | Role |
|---|---|
| Audience context | CRM, CDP, or ecommerce customer record |
| Rule engine | Which template variant, which products eligible |
| LLM fill (scoped) | Generate text only inside approved slots |
| RAG (scoped) | Pull approved proof points—no invented stats |
| Recommendation API | SKU picks with inventory filter |
| Send-time model | Optimal hour/day per contact |
| Render service | Returns HTML fragment or merge payload to ESP |
| Suppression | Unsub, bounce, frequency cap, competitor list |
Default: no full-email LLM without locked header/footer and legal footer.

Architecture
Campaign trigger (ESP, campaign manager, cart event)
For each contact (or batch chunk)
Load context (CRM, orders, browse, scores)
Rules → template variant + product IDs
LLM/RAG fill slots + send-time score
Render HTML / merge JSON → ESP send API
Events → analytics + model retrain
Latency — render < 200–500 ms per contact at scale via queue workers (scoped targets)
PII — process in your region; no training on inboxes without opt-in
Use cases
| Scenario | Personalization angle |
|---|---|
| B2B nurture | Industry intro + case study block + CTA by lead score |
| Ecommerce promo | Category affinity products + send-time |
| Post-purchase | Cross-sell from order history—not generic catalog |
| Renewal reminder | Health tier messaging from churn model |
| Webinar invite | Role-based value prop (SDR vs VP) |
| Agency multi-brand (scoped) | Separate brand voice profiles per client |
Different from AI cart recovery—general lifecycle email, not only abandonment sequences. AI cart recovery.
Integrations
| System | Role |
|---|---|
| Zoho CRM + Campaigns | Fields, lists, send, activity sync |
| Salesforce / HubSpot (scoped) | Marketing Cloud or transactional hooks |
| Ecommerce (Shopify, custom) | Orders, browse, cart |
| Product recommendation engine | SKU blocks |
| Campaign manager | Sequence step calls render API |
| CDP / warehouse (scoped) | Unified customer profile |
{FirstName} is not personalization. We personalize intent, products, and timing—inside templates your legal team already approved.
