🎥 Set up an Echo campaign in 9 minutes
In this Quick Start Guide tutorial, learn how to create, track, and evaluate your Echo campaign.
A. Social sharing card
The visual must be provided following these specifications:
Ideally square format (landscape works too in general, but on some platforms might lead to cropped visuals).
Minimum size: 1080x1080px
PNG format
Enough blank space to position name, position, and custom fields
Enough blank space to position the profile image
Your PNG CAN have a transparent cut-out for circular (or other shapes) profile pictures. You can do that with tools like Photoshop
💡Tip: You can use our AI image generator to create the sharing card visuals for you. Read more about Echo's AI tools here.
B. Sharing Text
Preferably <280 characters (for X/Twitter)
Should include all your primary hashtags!

C. Naming fields
These fields will auto-populate with the user's details if they are logged in to their social media account. By default, Echo provides fields for:
First name / last name
Position
You can also add up to 3 custom fields such as:
Position
Company
Exhibition booth number
Etc.
D. Sharing URL
This is the URL we'll attach to every shared post It's the URL you want Echo to drive traffic, such as your event registration page or your social media wall.
You can use custom UTM-paramters to track traffic through this link. You can add UTM values by going to Edit Campaign > Tracking & Embed > UTM Parameters.
