Setting a substitute font for a VBA created Email if recipient doesn't have the body font

Hi,

Can anyone help with this problem?

Is there a way to set a substitute font in a VBA created email?

At work, the chosen email font is Calibri, however some managers now read their emails on their shiny iPhones, but the email doesn't display in Calibiri

If you send a manual HTML email, the email is displayed in Arial font

However, if you send an HTML email created by VBA, the email is displayed in Times New Roman

Is there any way to program the VBA email to display in arial font if the recipient doesn't have the set body font, in this case Calibiri.

Hope that makes some sense!

Thanks in advance for any help!
