I've been using custom fonts (TradeGothic Condensed) in emails for a client for the last year, knowing that they weren't all that widely supported but, for my client, it was most important to have the custom font available in iOS as it is part of their brand identity. It worked great for a year, but in the last few weeks I've noticed that the Apple Mail and native iOS mail client have been replacing the font with another, and all in bold italic. Has anyone else come upon this change? Is there a way to fix it?
