How to connect SendGrid and Supabase

Step 1: Create a new workflow
Step 2: Add and configure nodes
Step 3: Connect
Step 4: Customize and extend your integration
Step 5: Test and activate your workflow

Step 1: Create a new workflow and add the first step

In n8n, click the "Add workflow" button in the Workflows tab to create a new workflow. Add the starting point – a trigger on when your workflow should run: an app event, a schedule, a webhook call, another workflow, an AI chat, or a manual trigger. Sometimes, the HTTP Request node might already serve as your starting point.

Step 2: Add and configure SendGrid and Supabase nodes

You can find SendGrid and Supabase in the nodes panel. Drag them onto your workflow canvas, selecting their actions. Click each node, choose a credential, and authenticate to grant n8n access. Configure SendGrid and Supabase nodes one by one: input data on the left, parameters in the middle, and output data on the right.

Step 3: Connect SendGrid and Supabase

A connection establishes a link between SendGrid and Supabase (or vice versa) to route data through the workflow. Data flows from the output of one node to the input of another. You can have single or multiple connections for each node.

Step 4: Customize and extend your SendGrid and Supabase integration

Use n8n's core nodes such as If, Split Out, Merge, and others to transform and manipulate data. Write custom JavaScript or Python in the Code node and run it as a step in your workflow. Connect SendGrid and Supabase with any of n8n’s 1000+ integrations, and incorporate advanced AI logic into your workflows.

Step 5: Test and activate your SendGrid and Supabase workflow

Save and run the workflow to see if everything works as expected. Based on your configuration, data should flow from SendGrid to Supabase or vice versa. Easily debug your workflow: you can check past executions to isolate and fix the mistake. Once you've tested everything, make sure to save your workflow and activate it.

Outreach for your product using Apollo, LinkedIn, GPT-4.1 and SendGrid

🔥 TLDR
Build a scalable, AI‑driven email outreach pipeline that:
Scrapes up to 500 leads from Apify
Enriches profiles with LinkedIn work history & posts
Filters and scores leads via Apollo.io
Generates personalized HTML emails with GPT‑4.1 .

👥 Who’s It For
Sales teams, growth marketers, and founders who need:
High‑touch cold outreach at scale
Data‑driven personalisation using real profile insights

⚙️ How It Works / What It Does
Apollo Scraper: Uses Apify HTTP nodes (no hard‑coded API keys) to pull lead data.
Supabase Sink: Persists email, linkedin_url, and ingestion timestamp.
LinkedIn Enrichment: Fetches career history and latest 5 posts via RapidAPI.
Data Validation: Conditional nodes drop incomplete or irrelevant leads.
Product Description Agent: Creates a customer profile based on the product and how it can help them.
Story Agent: Has the persona, style of speech and rules to generate reply for the customer based on the pain points and solution found by the Product Description agent.
HTML Modifier: Contains a fix format to keep the output format of each mail consistent and also generate a subject for the mail.
SendGrid Dispatch: An SMTP service which delivers emails in large quantity and also keep your mail spam free otherwise if you use gmail node your mail will go staright to spam; updates status=true/false in Supabase.

🛠️ How to Set Up
Clone the workflow JSON into your n8n instance.
Configure environment variables for Apollo.io, RapidAPI, OpenAI, SendGrid, and Supabase.
Rename credentials and test each HTTP node.
Activate the workflow and monitor executions in n8n’s UI.

✅ Requirements
n8n 0.300.0+
Accounts & API keys for Apollo.io, RapidAPI (LinkedIn), OpenAI, SendGrid, Supabase
Supabase to store LinkedIn id and gmails of leads, also useful to eliminate the risk of having duplicate data.

🎨 How to Customize
Adjust lead batch size in the Apollo HTTP node.
Swap the HTML email template to match your brand.
Add A/B subject‑line experiments by cloning the Email Agent.

> 🔐 Security Reminder: All credentials must be stored in n8n’s credential manager—never hard‑code API keys in HTTP nodes.
