Some fonts are incorrectly defined in the mailing.
E.g. Arial or Open Sans. Links to Google Fonts are inserted, but the fonts cannot be accessed under Google Fonts. See link.

According to GDPR, the fonts should be retrieved from the Mailjet server or the customer's server and not from a third source. The retrieval of Google Webfonts should therefore be changed as a matter of urgency.

It should also be possible to specify the font for the fallback.
