Hebrew campaigns
Hebrew messages display right to left automatically, both in the editor and in what the prospect receives.
Placeholders are localized too:
{first_name},{last_name}, and{spear_profile_first_name}are transliterated into Hebrew instead of staying in Latin script (e.g. "היי דניאל" instead of "היי Daniel").
