Clay + Sendblue — Data Enrichment Meets iMessage Outreach

Enrich leads in Clay with dozens of data points, then trigger personalized iMessage outreach via Sendblue's REST API. Turn enriched data into blue bubble conversations that actually get replies.

How to Connect Clay + Sendblue

Build & Enrich in Clay

Create a Clay table with your prospect list. Use Clay's enrichment providers to add mobile phone numbers, company data, job titles, funding info, and tech stack details.

Get Sendblue API Keys

Sign up for a Sendblue account and grab your API key and secret from the dashboard. These authenticate the HTTP requests Clay will send to Sendblue.

Add an HTTP Request Column

In Clay, add an HTTP request column that calls POST https://api.sendblue.co/api/send-message. Map Clay's enriched fields into the message body for personalization.

Capture Replies via Webhooks

Configure Sendblue webhook callbacks to receive delivery confirmations and incoming replies. Route responses to your CRM, Slack, or back to Clay for tracking.

Key Features

Deep Personalization

Clay enriches leads with 50+ data points. Use name, title, company, funding stage, tech stack, and LinkedIn bio to craft iMessages that feel genuinely researched.

HTTP Request Integration

Clay's HTTP request column calls the Sendblue API directly. No middleware needed — each enriched row in your Clay table becomes a personalized iMessage.

Webhook Callbacks

Sendblue sends real-time delivery and reply notifications via webhooks. Route them to Slack, your CRM, or back to Clay for response tracking.

Smart Fallback

Sendblue detects iMessage availability automatically. iPhone contacts get blue bubbles; Android contacts receive SMS. No manual segmentation required.

Media & vCards

Send images, PDFs, and contact cards alongside your messages. vCards let prospects save your info with one tap — increasing callback rates.

Scalable Outreach

Process hundreds of enriched leads through Clay and Sendblue. Each message is personalized, but the workflow scales with your prospect list.

Why Clay + iMessage?

Clay is the most powerful data enrichment tool for sales teams. It pulls data from dozens of providers to build rich prospect profiles. Sendblue turns those profiles into personalized iMessage outreach that lands in prospects' pockets as blue bubbles — the most trusted messaging format on iPhone.

Data-driven personalization: Generic "Hey {first_name}" messages get ignored. When you reference a prospect's tech stack, recent funding round, or job change in an iMessage, response rates jump. Clay gives you the data; Sendblue gives you the delivery channel.

Sendblue does not have a native Clay integration — you connect the two via the Sendblue REST API, which Clay calls directly from HTTP request columns. This gives you full control over message content, timing, and logic. Filter enriched rows, add conditional personalization, and send only to verified mobile numbers.

For CRM logging, pair Clay + Sendblue with a native CRM integration: HubSpot, Salesforce, or Close. You can also combine with Apollo.io for additional enrichment sources.
