The zzTakeoff logo on the new-user invite email is very large, and the 'accept invitation' button is obscured by the massive size of the logo. Had to help a few users accept their invite. The below screenshot is 2614x903.
The embedded logo is 2199x367 (attached) and displays at 100% in Outlook build 2411
Hey Eric, thanks for reporting this issue! It looks like the formatting issue was specific to Outlook email clients (emails displayed fine on Gmail).
We just fixed the email formatting and this issue should be resolved. I've attached an image of the new email displayed in Outlook.
