Hi Kim. You cannot customize the logo size in the Welcome Email. 

However, you can customize the body text, coloring, and font. When you change the coloring and the font from the  Admin Panel> Theme section, the same will be applied to the welcome email as well. 

1. Upgrade Tribe25 to access the SendGrid integration, and to be able to use your custom domain
2. Set up your custom domain14 in Tribe
3. Create a free SendGrid account13
4. In SendGrid, create an API key13
5. Copy and paste the API key into Tribe's SendGrid integration13 and enable SendGrid in Tribe
6. In SendGrid, click on Sender Authentication in Settings
7. Follow the steps by step instructions to set up the CNAME records for your domain
8. Once everything verifies properly, it should work great
