When you send a proposal from Better Proposals, it comes in a beautifully designed email with your logo at the top. This logo should be suitable for a white background.
Change the logo on your client emails
To access your email settings, hover over your profile picture in the top right corner and click ‘Settings’ in the drop down menu.
Once you’re there, just click the brand you wish to edit under ‘Branding’ section and find the ‘Email’ tab among the brand settings.
From there, click 'Browse for logo' and replace it with the logo you want to show in your client emails.
It's best to use a transparent PNG with a minimum width of 400px.
