How to connect SendGrid to Google Sheets

Email campaigns go out through SendGrid. Performance data — opens, clicks, bounces, unsubscribes — stays locked in SendGrid's dashboard. If you want to connect SendGrid to Google Sheets, you are building a bridge between your sending engine and the spreadsheet where your team actually reviews, compares, and acts on results.

There is no native integration. SendGrid does not push data to Google Sheets directly. You need either an automation platform, the SendGrid API with a script, or a serverless workflow. According to Twilio SendGrid's 2025 Email Benchmark Report, the average email open rate across industries sits at 21.5%, and bounce rates above 2% signal deliverability problems. A 2025 Litmus survey found that 43% of email marketers still track campaign performance in spreadsheets, even when dashboard tools are available.

Unlike generic AI automation posts, this guide shows real CodeWords workflows — not just theory.

TL;DR

• SendGrid has no native Google Sheets integration — all connections require an intermediary.
• Automation platforms handle simple event logging but struggle with aggregate stats, batch processing, and historical data pulls.
• CodeWords workflows give you full control over the SendGrid API, data transformation, and Sheets output.

What are the main ways to connect SendGrid to Google Sheets?

Three approaches, ranked by flexibility.

Method 1: Automation platform

Zapier and Make offer SendGrid triggers (e.g., new contact added, email event via webhook) and a Google Sheets action (append row). Set up a Zap that fires on each event and logs it.

Pros: no code, fast setup. Cons: per-event pricing adds up with email volume (a 50,000-email campaign generates 50,000+ events), limited to the triggers the platform exposes, no aggregation or transformation.

Method 2: Google Apps Script

Write a script in Google Sheets that calls the SendGrid API on a timer. The script fetches stats (global or per-campaign), parses the JSON, and writes rows. This is free but requires maintenance — API changes, auth token refresh, and error handling are your responsibility.

Method 3: CodeWords serverless workflow

Build a Python workflow on CodeWords that uses the SendGrid API to pull whatever data you need — campaign stats, event logs, contact lists, suppression groups — transforms it, and writes it to Google Sheets. Schedule it, trigger it from Slack, or run it on demand.

CodeWords handles auth, serverless execution, retry logic, and gives you LLM access for AI-powered analysis of your email data.

How do you pull campaign stats into a spreadsheet?

The most common use case: log campaign performance over time.

Step 1: Authenticate. Store your SendGrid API key in CodeWords secrets. Store your Google service account credentials for Sheets access.

Step 2: Fetch stats. Call the SendGrid Stats API (GET /v3/stats) with a date range. The response includes requests, delivered, opens, unique opens, clicks, bounces, spam reports, and unsubscribes — aggregated by day.

Step 3: Transform. Calculate derived metrics: open rate (unique opens / delivered), click-through rate (clicks / unique opens), bounce rate (bounces / requests). Round to two decimal places.

Step 4: Write to Sheets. Use the Google Sheets API to append rows to a "Campaign Stats" tab. Each row contains the date, campaign name, and all metrics. Alternatively, overwrite a fixed range to maintain a rolling dashboard.

Step 5: Schedule. Run the workflow daily at midnight to capture the previous day's stats. Over time, you build a historical performance spreadsheet without any manual work.

How do you log individual email events?

SendGrid's Event Webhook sends real-time POST requests for every email event: delivered, opened, clicked, bounced, dropped, deferred, unsubscribed, spam report.

To capture these in Google Sheets:

1. In CodeWords, create a serverless endpoint that accepts POST requests.
2. Register that URL as SendGrid's Event Webhook URL (Settings → Mail Settings → Event Webhook).
3. Each incoming event contains the email address, event type, timestamp, campaign metadata, and user agent.
4. The workflow batches events (e.g., every 100 events or every 60 seconds) and appends them as rows to a "Raw Events" sheet.

Batching matters. A 100,000-email campaign generates hundreds of thousands of events. Writing one row per event in real time would hit Sheets API rate limits (300 requests per minute per project). Buffering events and writing in batches of 100-500 rows is the reliable pattern.

Think of it like a funnel: events pour in continuously, but you write to Sheets in measured doses.

Can you build an email performance dashboard in Sheets?

Yes. Combine the campaign stats workflow with a Sheets template:

• Tab 1: Daily Stats — automated by the daily stats workflow. Columns: date, sent, delivered, opens, clicks, bounces, unsubscribes, open rate, CTR.
• Tab 2: Campaign Comparison — pivot table or formulas that compare campaigns side by side.
• Tab 3: Alerts — a CodeWords workflow checks the latest stats and highlights anomalies: open rate dropped below 15%, bounce rate spiked above 3%, unsubscribe rate above 0.5%. Flags these rows in red and optionally posts a Slack alert.

OpenAI or Anthropic can generate a natural-language summary of the week's email performance, written directly into a "Weekly Summary" cell.

How do you sync SendGrid contacts to Google Sheets?

The Marketing Campaigns API lets you export contact lists. A CodeWords workflow can:

1. Call GET /v3/marketing/contacts with pagination.
2. Flatten contact fields (email, first name, last name, custom fields).
3. Write to a "Contacts" tab in Sheets — with a full sync or incremental append based on updated_at timestamps.

Use this to build a master contact sheet that feeds other workflows: enrichment, segmentation, cross-referencing with CRM data.

FAQs

Can I send emails from Google Sheets via SendGrid?

Yes. A CodeWords workflow reads recipient data from Sheets, builds personalized email payloads, and sends them via the SendGrid Mail API. This is useful for small campaigns or transactional emails triggered by spreadsheet data.

What SendGrid API permissions do I need?

For stats: read access to Stats and Marketing. For events: Event Webhook configuration. For contacts: read access to Marketing Contacts. Generate a restricted API key with only the permissions your workflow needs.

How do I handle SendGrid API rate limits?

SendGrid allows up to 600 requests per minute on most plans. For bulk operations, paginate and add delays between batches. CodeWords handles retry logic with exponential backoff automatically.

Can I track email events per recipient in Sheets?

Yes. Use the Event Webhook to capture per-recipient events. Each row in your sheet logs one event for one email address, with a timestamp and event type. Filter in Sheets to see a single recipient's journey.

Start syncing SendGrid and Google Sheets

Manual CSV exports and dashboard screenshots are inefficient. A CodeWords workflow automates the data pipeline — stats, events, contacts, and AI-powered analysis — directly into the spreadsheet your team already uses.
