 When sending several emails successive, not all data are cleared from
 phpmailer.
 In my case, I'm sending two emails :
 - One first email validation in HTML (with text and Html as altbody)
 - One second email with some raw data, and custom content-type.

 The second email keep the variable "AltBody" from the first email, so
 wp_mail consider it as a multi part email. And as so, wp_mail() change the
 content-type from my custom kind to "multipart".

 It comes from the re-use of global $phpmailer, instead of create a new
 phpmailer.
 Phpmailer class needs a better clear of all previous variables.
