Deliverability hack: Invisible text in Klaviyo

Max Sturtevant·Dec 2024

Demo summary

Demonstrates how to paste large blocks of text into a Klaviyo email and make it invisible (white text, small font) to improve the image-to-text ratio for spam filters.

Step-by-step

Add a text box to the bottom of the Klaviyo email
Paste a large block of text into the text box
Center the text
Change the font size to 5
Change the text color to white to match the background
Adjust the line spacing to 5% to minimize white space

Tips

Use a large block of text, such as an 'About Us' section, to improve the image-to-text ratio for spam filters
Ensure the text color matches the background exactly to make it invisible to recipients while remaining visible to Google

Highlights

“completely invisible but there's a ton of text right there and this is going to help with our inbox placement”
