Web feeds are the secret to keeping your recurring email campaigns fresh and relevant. Here's how to set them up, even if you don't have one yet.

Option 1: Connect Your Existing Web Feed

If you already have an RSS or XML feed, connecting it to Klaviyo is straightforward.

Steps:

Go to Content > Web Feed in your Klaviyo account
Click Create Web Feed
Enter your feed URL (e.g., https://yourblog.com/feed.xml)
Map feed fields to Klaviyo properties:
- Title → Title
- Description → Description
- Link → URL
- Publication Date → Date
Test the feed to ensure it's pulling data correctly
Click Save

Most blogs and CMSs automatically generate RSS feeds at /feed, /rss, or /feed.xml. Follow Klaviyo's web feed guide for detailed instructions.

Option 2: Create a Feed Using Google Sheets + RSS App

Don't have a web feed? Create one using Google Sheets and an RSS app.

Perfect for full control over content timing and easy date-based filtering.

Setup Steps:

Step 1: Create Your Content Sheet

Create a new Google Sheet
Set up columns:
- A: Title (your content headline)
- B: Description (summary or excerpt)
- C: URL (link to full content)
- D: Date (publication/relevant date)
- E: Category (optional - for filtering)

Step 2: Add RSS App
Search for "Google Sheet + RSS app" to find RSS generator add-ons.

Step 3: Configure Date-Based Filtering

To show only today's relevant content, set up your sheet with date logic:

Example Sheet Structure:
Title                    | Description              | URL                    | Date       | Show Today
Monday Motivation        | Weekly inspiration...    | https://...           | 2025-09-09 | =IF(WEEKDAY(TODAY())=2,TRUE,FALSE)
Tuesday Tips            | Helpful strategies...     | https://...           | 2025-09-10 | =IF(WEEKDAY(TODAY())=3,TRUE,FALSE)
Daily Deal Alert        | Today's special offer..   | https://...           | TODAY()    | TRUE

Date Filtering Formulas:

Weekday-specific: =IF(WEEKDAY(TODAY())=2,TRUE,FALSE) (Monday = 2)
Monthly content: =IF(DAY(TODAY())=1,TRUE,FALSE) (1st of month)
Date ranges: =IF(AND(TODAY()>=DATE(2025,9,1),TODAY()<=DATE(2025,9,30)),TRUE,FALSE)

Step 4: Generate RSS Feed

Configure your chosen RSS app to read from your sheet
Set it to only include rows where "Show Today" = TRUE
Get your generated RSS URL
Connect this URL to Klaviyo (follow Option 1 steps)

Option 3: Use Napkin.io for Serverless Feeds

Napkin.io is a serverless platform (like AWS Lambda) that lets you quickly deploy custom feed logic.

What It Is:

Serverless functions for creating dynamic feeds
Code-based approach - requires some technical setup
Highly customizable - complex filtering and logic possible
Fast deployment - from code to live feed quickly

When to Use:

You need custom filtering logic beyond simple date rules
You want to combine multiple data sources in one feed
You need real-time updates based on external APIs
You have engineering resources available for setup

Getting Started:

Work with a developer to write your feed logic
Deploy function to Napkin.io
Get your feed endpoint URL
Connect to Klaviyo using the URL
Test and monitor feed performance

Example Use Cases:

Inventory-based deals: Only show products that are in stock today
Weather-dependent content: Different content based on user location/weather
API-driven feeds: Pull from multiple external sources (social, news, etc.)
Complex date logic: Multi-timezone support, business day calculations

Content Ideas by Day

Daily rotation: Monday motivation, Tuesday tips, Wednesday products, Thursday stories, Friday roundups
Seasonal: Holiday promotions, seasonal products, industry events
Time-sensitive: Flash sales, weekly deals, monthly features

Testing Your Feed

Check feed URL in browser (should show XML/RSS)
Test updates by making changes
Preview in Klaviyo before going live
Send test emails to verify everything works

Quick Tips

Plan content 1-2 weeks ahead for consistency
Test date formulas in Google Sheets before publishing
Keep descriptions under 200 characters for better display
Monitor performance to see what content works best
