I'm using WordPress 4.9.8, CiviCRM to 5.4.0, CiviRules 2.1 and E-mail API 1.17.2. I've created a Rule that send email to contact when added to a group. I've used some token here https://docs.civicrm.org/user/en/latest/common-workflows/tokens-and-mail-merge/#available-tokens
But only token {domain.email} and {domain.name} can show. Other tokes is empty. Is it bug?
