Thank you for your answer Suman,
I have 1.1.2 Version of the plugin. I changed the Logo resolution and it worked.
However email Tag line and Title fonts and sizes are not in line with the rest of the message body written for the user. (where can I set the Font and the size?)
Is there any chance to control the Font and the size when sending an email to the user?
The default font size of the “Email Subject” is quite big.
?t would be a great help to add Font & Size option to the Text editor.
Once again thank you for this very useful plugin.
