As a merchant, you are able to add your brand logo to the Ongoing™️ Build a Box.
This feature is available on the Ongoing Pro plan, here's how to upgrade if you're interested in this branding package which also allows you to add a brand logo to the emails as well as the subscriber portal.
From Ongoing > Settings > General > Branding > Add Logo
If the logo looks too small or pixelated, you might want to play around with uploading different versions (sizes and colors) of your brand logo until it appears how you want it too look.
If you need any help with uploading your brand logo to Ongoing, please get in touch & we can help you with this.
