When you write an email template and use the placeholder {{company}} it can but must not happen that the company name is displayed incorrectly. Let me give you an example:

The company you want to reach out to has the name "Schmidt & Schultze". Now you use the placeholder {{company}} and in rare cases we have seen that the company name will be displayed in the final mailing as "Schmidt & Schultze". In order to avoid this error, please use an additional bracket on both sides of the placeholder, like this: {{{company}}}

As an internal point in your your workflow we recommend that you always preview your mailing templates, to make sure if there are errors like this, before you activate the campaigns.
