Caramel Decides Who Gets the Email. SendGrid Makes Sure It Arrives.
Caramel's AI agent determines which customers receive which messages and when. SendGrid's delivery infrastructure handles the scale, the reputation management, and the deliverability that ensures those messages land in inboxes rather than spam folders. Together, the intelligence and the infrastructure produce email campaigns that are both strategically sound and operationally reliable.
What the SendGrid + Caramel Integration Makes Possible
SendGrid is one of the world's most trusted email delivery platforms — powering transactional and marketing email for companies that send billions of messages at scale, with the deliverability infrastructure, IP reputation management, and analytics tooling that high-volume email programmes demand. Caramel uses SendGrid as the delivery infrastructure layer for its email channel, combining Caramel's AI-driven segmentation, personalisation, and campaign automation with SendGrid's operational email capabilities. This means every email campaign launched from Caramel — whether a loyalty programme update, a post-purchase sequence, a win-back campaign, or a transactional confirmation — is routed through SendGrid's delivery infrastructure to maximise inbox placement rates. Marketers work inside Caramel's interface to design, segment, and schedule campaigns. SendGrid handles the infrastructure underneath — managing send reputation, processing bounces and unsubscribes, and providing detailed delivery analytics that Caramel surfaces alongside its broader campaign performance data. The result is an email channel that combines strategic intelligence with operational excellence.

Integration Features
Enterprise-Grade Email Delivery at Scale
When Caramel launches an email campaign to thousands or hundreds of thousands of recipients, SendGrid's delivery infrastructure handles the send volume with the throughput, queuing, and retry logic that enterprise-scale email demands. Campaigns that would strain a lightweight email provider send reliably through SendGrid — with no degradation in delivery speed or inbox placement as list size scales.
Sender Reputation Management and IP Warming
SendGrid manages the sender reputation of the IP addresses used for Caramel email sends — monitoring engagement signals, managing suppression lists, and automatically adjusting send behaviour to protect domain reputation. For businesses scaling their email programme, SendGrid's IP warming protocols ensure deliverability is maintained as send volume grows.
Transactional Email Reliability for Time-Sensitive Messages
Loyalty tier upgrade confirmations, booking confirmations, password resets, and purchase receipts are transactional messages that customers expect immediately. Caramel routes these time-sensitive transactional sends through SendGrid's dedicated transactional infrastructure, which is optimised for speed and reliability rather than bulk marketing throughput — ensuring critical customer communications arrive promptly.
Bounce and Unsubscribe Processing
SendGrid processes all hard and soft bounces, spam complaints, and unsubscribe requests from Caramel email sends, automatically suppressing problematic addresses and feeding the outcome data back into Caramel's customer profiles. Bounced email addresses are flagged in the unified profile. Unsubscribe requests are honoured immediately across all future Caramel email sends — maintaining compliance and list health automatically.
Delivery Analytics Integrated With Campaign Performance
SendGrid's granular delivery data — per-message open events, click events, bounce classifications, spam report rates, and unsubscribe events — is accessible alongside Caramel's campaign performance metrics. Marketers see email delivery health and engagement data in the same reporting context as WhatsApp, SMS, and loyalty programme performance — without switching between platforms.
Dynamic Email Personalisation at Delivery Scale
Caramel builds personalised email content — loyalty tier status, point balances, personalised offers, recommended products — and passes the variable data to SendGrid at send time. SendGrid renders and delivers individually personalised messages at scale without requiring templating work to be done outside Caramel. Each recipient receives an email built from their specific Caramel profile data.
How It Works Together
Loyalty Programme Email Sends at Scale Without Deliverability Concerns
A retail brand with 200,000 loyalty members runs a monthly tier status update email. Caramel segments the list, personalises each email with the recipient's current tier, point balance, and next tier threshold, and routes the entire send through SendGrid's infrastructure. Deliverability is managed by SendGrid's reputation systems. The marketing team sees open rates and click rates in Caramel's reporting interface without managing the underlying email infrastructure.
Transactional Booking Confirmations That Arrive in Seconds
A restaurant group sends booking confirmation emails through Caramel when guests complete a reservation. The time-sensitive transactional sends are routed through SendGrid's dedicated transactional infrastructure — separate from bulk marketing sends — to ensure confirmations arrive in the guest's inbox within seconds of booking, not minutes. Loyalty point credit notifications travel the same route.
Win-Back Campaign With Suppression of Recently Unsubscribed Contacts
Caramel identifies a segment of lapsed customers for a win-back email campaign. SendGrid's suppression list management ensures that customers who have previously unsubscribed are automatically excluded — without the marketing team manually cross-referencing suppression files before each send. GDPR compliance is maintained automatically at the infrastructure level.
A/B Test Email Campaigns With SendGrid Delivery Analytics
A marketing team tests two subject lines for a loyalty promotion email. Caramel splits the eligible segment, sends both variants through SendGrid, and surfaces the delivery and engagement data — open rates, click rates, conversion events — in a unified performance view. The winning variant is identified from SendGrid-validated delivery data rather than server-side estimates.
Post-Purchase Sequence Triggered by Loyalty Event
A customer completes a first purchase and is enrolled in the loyalty programme. Caramel triggers a post-purchase email sequence — a welcome email, a loyalty programme explainer, and a points statement after seven days — each routed through SendGrid for reliable delivery. The sequence is timed by Caramel's automation logic. The delivery reliability and inbox placement are managed by SendGrid.
Seasonal Campaign to 500,000 Recipients Without Infrastructure Management
A CPG brand runs a seasonal campaign to its entire loyalty database of half a million contacts. Caramel handles the segmentation and personalisation. SendGrid handles the send volume — managing the send queue, processing at scale, monitoring delivery rates in real time, and alerting if any deliverability issues emerge during the send. The marketing team focuses on campaign strategy rather than email infrastructure.
