An IFTTT recipe works this way:
{
âtokenâ: âTOKENâ,
âcontentâ:"<<<{{Subject}}>>>",
ânoteâ:"<<<{{Body}}>>>"
}
Use the <<<*>>> brackets to escape the text content. IFTTT probably is grabbing some encoding or html in the email that is causing the failure. I just set this up for a handful of emails with success.
